Early in May 1947, a United States Geological Survey field party of five was flown by ski plane to the headwaters of the Utukok River in northwestern Alaska, about 200 miles southwest of Barrow. Three 18–foot canvas boats of a special folding design were taken in along with enough equipment for four months. Food caches had been flown in to six localities on the 200–mile–long river a short time before the group landed. When the “break–up” came late in May the party started down the river working out the geology of the area from a series of 18 camps which were established before reaching the Arctic Ocean in August.

During the season 17 archaeological sites were discovered. It is believed that most of these sites are of Eskimo origin and are probably fairly recent. However, an important exception is a well–made Folsom point, announcement of which has been made.

A preliminary investigation of the geology of the ridge north-\nwest of the lower end of Eklutna Lake was made in the period\nJune 11-18, 1947, by the writer, assisted by L. A. Hale. The\npurpose of this study was to obtain geological information bearing\non the feasibility of constructing a tunnel through this ridge as\npart of a hydroelectric power development under consideration by\nthe city of Anchorage.

\n
\n

Several traverses were made up each side of the ridge in a\nbelt judged to include the most logical routes for the proposed\ntunnel. For the purpose of localizing the study two tentative\nroutes were selected, of which one would require the shortest possible\nlength of tunnel, and tho other would be somewhat longer but would\nplace the lower portal of the tunnel at a location considered to\nbe the most favorable for the construction of the penstock and\npower plant. The first route extends northwestward from tho most\nwesterly embayment on the north shore of the lake to the canyon\nabout half a wile east of Pioneer Creek (see map) . The second\nroute extends from tho same point in the lake to the nearest\npoint on the steep slope southwest of the mouth of Goat Creek.\nThe distance along the first route from the lake shore (elevation\n862 feet) to the 800-foot contour on the north side of the ridge is 4.3 miles. The distance between corresponding points along the\nsecond route is 4.5 miles. The length of the tunnel would exceed\nthese distances by amounts depending on the elevation and grade at\nwhich the tunnel is constructed.

The only known gypsum deposits in Alaska are on northeastern Chichagof Island, southeastern Alaska, at Iyoukeen Cove (fig. 1). The area first developed and for a time worked by the Pacific Coast Gypsum Co. is approximately 1 mile upstream from the mouth of Gypsum Creek at an elevation of about 70 feet (fig. 2). The second deposit, known as the Gypsum-Camel property, is on tidewater 12 miles northeast of the mouth of Gypsum Creek (fig. 2). Iyoukeen Cove is about 35 air miles southwest of Juneau and is on both the mail-boat and the airline routes between Juneau and Sitka.

The two deposits were examined by a Geological Survey party during the summer of 1946. Topographic and geologic maps were made of the vicinity of both deposits (figs. 2 and 3). Accessible underground workings at the Gypsum-Camel property also were mapped,

In 1946 U. S. Geological Survey Party 2 was assigned the task of carrying out detailed structural and stratigraphic investigations in the area of Maybe Creek*. Field studies indicated the presence of a large anticlinal structure whose axis lies just south of Wolf Creek. Later structural data compiled from aerial photographic studies indicated that the anticline is a closed structure 8-9 miles long, and as much as 6 miles wide. The evidence for a closure on the east end of the structure appears very strong, but not enough evidence was obtained to prove closure on the west end. In 1947 U. S. Geological Survey Party 1 spent two weeks at Wolf Creek, mapping bedding traces on the west end of the structure with plane table and alidade, in an attempt to prove or disprove west closure on the anticline.

The stratigraphy and structure of the area of the Colville north of Umiat was studied by U. S. GeologicaI Survey Party No. 1 during the period of May 31 to July 19, 1947. The. party, consisting pf two geologists, a cook, and a \"weasel\" mechanic, left Umiat in two \"weasels”. The weasels were used to transport the party and equipment from camp to camp, and also made it possible for the geologists to work as far as 15 to 20 miles out from a camp in one day. A ten-foot canvas-boat was carried along. During most of the month of June even the smaller tributaries to the Kogohokruk carried enough melt and run off water to make them navigable in the 10-foot boat. The party returned to Umiat on June 23, after traversing both the Kikiakrorak and the Kogohokruk Rivers, and several smaller tributaries to the Kogohokruk.

Geological Survey Party 4 began studies at a point on the Colville River 18 miles downstream from the mouth of the Killik River on July 19. From this point the studies were continued along the Colville River to near the mouth of Prince Creek. The investigation was completed on September 1 and the party returned to Umiat. A traverse was made along the lower half of Prince Creek and along one of its northern tributaries between September 8 and September 15. Canvas boats were used for transportation along the Colville River and a weasel was used to traverse Prince Creek. The party was composed of four members: R. L. Detterman and D. E. Mathewson, geologists; J. L. Townley, surveyor; and Charles Segal, cook.

During the summer of. 1947, U. S. Geological Survey Party No. 2 made a reconnaissance survey of the area between Awuna River and the divide north of the Kigalik River. The westernmost observations were made along the Awuna anticline to longitude about 157°30' W. and along the Kigalik anticline to longitude about 156°55'W. The easternmost work was done along the Knife Blade Ridge anticline at a longitude of about 154°30'W. Not all of this area was traversed, but a general idea of the area studied may be had by noting the distribution of dip and strike symbols on Figure 1. 

Parts of this area had been previously visited by Smith 1/ in 1927 as a part of his traverse from Allakaket to the Arctic Coast. In the period from about July 10 to August 5 his party ascended the Awuna River and Birthday Creek, portaged over the Kigalik-Awuna divide at Birthday Pass, and descended the Kigalik River to its mouth.

Various parties in the field season of 1946 worked in areas not far distant. Webber 2/ began his field work near the headwaters of the Meade River and measured a section across the Kigalik anticline about 25 miles beyond the westernmost observations made on that structure by Party No. 2. Work by Chapman and Thurrell 3/ along the Colville River parallels at a distance of three or four miles work by Party No. 2 in the vicinity of Knife Blade Ridge. The easternmost observations by Party No. 2 in the vicinity of Knife Blade Ridge are about 11 miles west of the area south of Maybe Creek mapped by Ray and Fischer.4/

Of the 1947 work of other field parties that of Thurrell 5/ along the Colville River is most closely related to this report. His thickness from the base of Zone A to his Trace No. 5 is included in Column 1 of Figure 3. Webber's work 6/ along the Ikpikpuk and Titaluk Rivers is also in a closely related area.

Party No. 2 moved through this area by weasel, the weasels being used extensively on the daily traverses. The party assembled at Umiat late in May and was flown out to a lake about one mile west of the Ikpikpuk River at latitude 69°40' N. where the weasels and initial supplies had been previously cached. Early in June the party moved south into the area in which it was to begin work. For the next several weeks the party worked in the area north of the Kigalik River, moving westward along the divide north of that river. At this time considerable work was done south of the Kigalik River, west of longitude 154°40'W. No closure was detected along the Kigalik anticline. Shortly after the middle of July the party moved southwestward to the vicinity of the Awuna anticline where a westerly plunge had been suggested from the study of aerial photographs. The general route of the party from then on was eastward along the divide between the Awuna and Kigalik Rivers. Due to the need to reach a food cache further east very little data was gathered in the area between Birthday and Section Creeks. It was intended to work this area by one or two spike trips from the camp at the head of Section Creek. However, after constructing a cross-section from data gathered by the party along Section Creek and by Thurreli in the area between the Colville and Awuna Rivers it became apparent that the strata exposed along the axis of the Awuna anticline were stratigraphically below the base of Zone A. It thus appeared that there would be little point in attempting to gather additional data in the area between Birthday and Section Creeks. The party continued eastward, working along the south flank of the Kigalik anticline. On September 1, the party camped about one mile west of the summit of Knife Blade Ridge. Because of unfavorable weather at this time only a small amount of field work was accomplished in the next week. Enough data was gathered to give a general picture of the structure here, but the data on stratigraphy and structure is far from exhaustive. On September 9 the party moved eastward, camping that night about 3 miles northeast of :Wolf Creek, and arriving at Umiat on the afternoon of September 10.

Aerial photographs were carried in the field and used to record the points at which observations were made. A considerable amount of data was recorded on the photographs. Approximate elevations were obtained, at first by aneroid barometers, and later by more sensitive airplane altimeters. Plane table and alidade were used in local traverses in the area north of the Kigalik River to obtain dips and strikes by the 'three-point method. Nearly all other dips and strikes recorded were measured by Brunton compass. Dips of 5° or less in the area south of the Kigalik River should, in general, be considered as dip components with only the approximate strike shown. These low dips were taken on bedding traces* where it was usually impossible to observe an accurate strike with the Brunton.

During the summer of 1946 the United States Geological Survey continued its program of stratigraphic and structural investigations in Naval Petroleum Reserve No. 4, northern Alaska. This report summarizes the results of work in the area of Maybe Creek (see inset, fig. 1). The area studied is southwest of Umiat and includes about 500 square miles lying generally between the headwaters and mouth of Maybe Creek. Structural data covering approximately 250 square miles of this area has been compiled from aerial photographic studies. The area is bordered generally on the north by the lake country and on the west by the Ikpikpuk River. Most of the area is north of Maybe Creek except for that part extending for 6 miles south of Maybe Creek between longitudes 153° 30' W. and 154° 20' W. The latitude of Maybe Creek is about 69° 15' N. The stream flows generally westward and at longitude 154° 40' W. unites with the eastward-flowing Kigalik River to form the Ikpikpuk River, which has a northerly course across the Arctic Slope to the ocean.

The area between 68° 3C' and 69° 08 N. latitude and between 154° and 155° 20 W. longitude was covered by U. S. Geological Survey party 4 during the period May 18 to September 2. Traverses were confined mainly to the valleys of the Kurupa, Oolamnagavik, and Colville Rivers inasmuch as very little rock is exposed in the interstream areas. This report is a compilation of the field data and of the results of office and laboratory work on rock specimens, fossils, and aerial photographs of the area. An interpretation of the structure and stratigraphy of this area is presented, and possible correlations with the Killik River area to the east are suggested. Some revisions of the conclusions in this report may become necessary in the light of further field work in adjacent areas and heavy mineral studies, but it is believed that any changes will not materially alter the geologic picture of the area.

Umnak Island is a dumbbell-shaped island in the eastern part of the Aleutian Islands. The island is 70 miles long and trends northeast-southwest. During 1946 volcano investigations were begun on the island and geologic mapping of most of northeastern Umnak Island was completed.

Okmok Volcano, a large, broad volcanic mountain rising to altitudes of 3,000 to 3,500 feet, occupies the central portion of northeastern Umnak Island. Fort Glenn, and Army airbase, is situated on the eastern end of the island, approximately 9 miles east of Okmok Volcano.

The central part of Okmok Volcano is indented by Okmok caldera, a large cliff-rimmed volcanic depression, 7%, miles in maximum diameter. The floor of the caldera is 1,500 to 2,500 feet below the caldera rim. Nine large cinder cones and many small ones lie on the caldera floor, chiefly along two arcuate zones. The caldera is drained by Crater Creek, which flows through a deep gorge cut in the northeastern wall of the caldera, and into Bering Sea.

Mount Tulik (4,111 feet altitude) and Mount Idak (1,918 feet altitude) arc important centers of ancient volcanism on the flanks of Okmok Volcano.

The geologic history of Okmok Volcano falls into three stages: The first includes the upbuilding of an ancient cone—Mount Okmok—to an altitude of at least 6;500 feet on the site of the present caldera; the second encompasses the destruction in a castastrophic eruption of the summit cone and the formation of the caldera; the third comprises events since the great eruption.

The earliest activity at Mount Okmok probably dates hack to the late Tertiary period. A composite cone, concave-sided in profile, was built by the alternate eruption of ash, coarse pyroclastics, and basalt flows. During the late Pleistocene, volcanic activity at Mount Okmok was greatly reduced and a topography of late youth was carved on the lower slopes by streams and valley glaciers. The summit of Mount Okmok was upwarped and dikes and necks were injected into the resulting fractures.

A large volcano at the site of Mount Idak was active during part of the period of upbuilding at Mount Okmok but became extinct during the middle Pleistocene. A parasitic vent, Mount Tulik, became active during the late Pleistocene and built a steep-sided cone before it became extinct, shortly before the formation of Okmok caldera.

A cataclysmic eruption terminated the period of dissection at Mount Okmok, 10,000 or more years ago. Part of the summit was blown away by the explosive violence of this eruption. Nuees ardentes (glowing clouds) and mudflows deposited tuff-breccia and agglomerate in the glacial valleys; later phases of the eruption blanketed the landscape with ash. Near the end of the eruption, the remaining upper part of the volcano collapsed along arcuate fractures: large blocks subsided several thousand feet and are now concealed in the caldera Poor beneath later deposits. A large arcuate fault block which subsided less than other blocks stands above the floor in the northeastern part of the caldera.

After the eruption, water collected in the caldera, forming a lake. Small but frequently active cones built islands in the lake and covered its bottom with pyroclastic debris. The lake eventually overflowed the lowest point in the rim of the caldera, and Crater Creek Gorge was carved, draining the lake and dissecting its deposits. Renewed movement along faults at the head of Crater Creek Gorge later raised a harrier which temporarily dammed the drainage and formed a second caldera lake.

Readjustments among subsided blocks in the caldera floor resulted in the folding of postcaldera deposits at several localities.

Much of the caldera floor has been covered by lava flows extruded from several cones since the draining of the first caldera lake. In general, however, volcanic activity seems to have declined since the great caldera-forming eruption. Seven eruptions from cones on the caldera floor have been recorded since 1817; the latest occurred in 1945.

As part of the geochemical program for the study of Okmok Volcano, temperatures of fumaroles were measured and samples of the products of the volcanic activity were analyzed. Average temperatures of fumaroles at one source of the 1945 lava low dropped from 320° C. on July 19 to 90° C. on September 5. The temperatures of fumaroles associated with the crater vents on both Cones A and C ranged from 95° C. to 97\" C., which is slightly below the condensation point of steam, indicating the presence of minor quantities of gases other than steam. The magmatic gases of fumaroles on Cone A consisted of carbon dioxide and sulfur dioxide in about equal amounts. The lack of halogen acid gases in the fumaroles and the steadily dropping temperatures arc interpreted as indicating that the present quiescence of Cone A will continue for many months. Solid reaction products from areas of fumarolic activity on Cone A are sulfates of sodium, calcium, and iron. The presence of hydrogen sulfide as the dominant sulfur gas at Cone C is interpreted as indicating the dying stages of the present cycle of activity of Cone C.

Thermal springs along the north base of Cone D have a total discharge of 115 cubic feet per second. Their average temperature is approximately 7° C. above the annual mean. From these figures it is calculated that about 21,000 kilogram calories per second are being given off by Cone D. The spring waters contain minute quantities of boron which is indicative of a magmatic source for a small part of the water. Hence, Cone D though quiescent is not extinct. Evidence is presented to show that most of the spring water from Cone D is meteoric in origin.

Thermal waters in the southwestern part of Umnak Island at Hot Springs Cove and south of Geyser Bight contain lithium, boron, arsenic, and antimony in solution. These elements are regarded as derived from underlying magmas that are in an advanced state of crystallization and hence not likely to give rise in the near future to large-scale volcanic activity.

Three portable seismographs were placed on the flanks of Okmok Volcano and were in operation during most of the period from June 1 to October 1. During this period several slight tremors and one moderate tremor, all of distant origin, were registered, but no tremors attributable to Okmok Volcano were recorded. The lack of tremor records, however, may have been due more to the insensitivity of the instruments than to the absence of tremors.
Earth-current investigations were carried on during August and September by comparison of records obtained from a base station at Fort Glenn with those from a station 1 V2 miles southwest of Mount Tulik. The records obtained indicate that no difference in magnitude or direction of earth currents existed between the Fort Glenn and Mount Tulik areas. The similarity of record obtained is indicative of the absence of a disturbing factor such as a large body of live magma beneath Okmok Volcano.

Future eruptions of Okmok Volcano are expected to he of mild to moderate intensity, and will he chiefly in the form of ash falls from vents inside the caldera. There would be a great menace—in the form of lava flows, nuees ardentes, and mudflows—to installations at Fort Glenn if a new center of volcanism came into existence on the east slope of Okmok Volcano. Small postcaldera cones now exposed there indicate that extra-caldera eruptions have occurred in the recent past and can be expected in the future. The possibility of another catastrophic eruption of the caldera-forming type, however, is remote.

Okmok Volcano should be kept under close observation, partly because of its possible threat to Fort Glenn and partly because it is a readily accessible locale for accumulating information on details of volcanic processes, applicable to other volcanoes in the Aleutian arc and elsewhere.

Geological Survey Party No. 4 was assigned an investigation of the Ikpikpuk and Titaluk Rivers and East Fork of the Ikpikpuk River mainly for the purpose of obtaining stratigraphic information which would be of use in determining the parts of the Upper Cretaceous sequence that underlie the areas investigated by United Geophysical Company parties 43 and 46.

A total of five days were spent in geological investigations of the Titaluk River with a Cub plane equipped with pontoons. The party was composed of the geologist and Don Hulshizer, pilot of Wien Alaska Airlines. The geologist and Ronald K. Sorem, field assistant, traversed the Ikpikpuk River by boat from the junction of Maybe Creek and the Kigalik River to near the junction of the East Fork. From the northernmost point reached by boat traverse, the river was examined by plane to north of latitude 70° N., but no outcrops or rubble indicating bedrock were seen. The East Fork was also examined from the air but no outcrops or rubble were observed.

U.S. Geological Survey Party 3 studied the geology of the Utukok River area and conducted a short reconnaissance of the Corwin-Cape Beaufort Region during the period May 12 to August 31, 1947. The upper part of the Utukok River was examined for several miles on either side while the lower, or Coastal Plain-portion, was necessarily limited to the few outcrops along the river.

During this study, the major emphasis was placed upon rocks of Upper Cretaceous age and their relationships to the underlying Lower Cretaceous rocks. All macrofossils, and numerous samples for porosity, heavy mineral, and microfossil determinations were collected.

A triangulation net was established by theodolite from Camp. 1 near the headwaters of the river to the mouth of Carbon Creek. The survey started and ended on measured base lines, and stations were determined by intersection and resection. Stations were selected, insofar as possible, on points that could be pin pricked on aerial photographs where adequate coverage was available, Horizontal control was computed for cartographic purposes. Vertical differences were computed from an elevation at Camp 1 assumed at 2,000 feet above sea level based upon two different airplane altimeter readings.

Most of the country is too rough for wheel landings with the exception of several gravel bars in the river between Camp 6 and the coast. Pontoon landings with a Cub plane can be made at most places on the river.

Driftwood, Adventure, Disappointment, Carbon, and Elusive Creeks are the main tributaries to the Utukok. At various localities, terrace gravels are common on divides of these streams. A terrace north of Driftwood Creek and about ten miles east of Camp 2 is covered with a deposit of gravel which is apparently, thick and is spread over an irregular area about two miles long and a half mile wide. A thin tundra cover obscures what is probably a much larger continuation of the gravel deposit. With favorable conditions plane landings could be made, but with a little construction work a commercial size airfield could be made.

Summary and Recommendations

\n
\n

1. Eklutna Lake and Eklutna Creek lie in a wide, deep, glaciated, trough-like valley. Downstream from the lake, this valley is partially filled with unconsolidated glacial and alluvial deposits.

\n
\n

2. Eklutna Lake dam site, located about 400 feet below the lake outlet, is suitable for a low dam of flexible, earth-embankment type. Adequate control of the stream can be obtained by raising the lake level about 50 feet to altitude 910 feet, which will provide hold-over storage from wet years to dry years. Such a structure will have a crest length of about 1,950 feet.
\nA. Bedrock is probably 200 to 475 feet below stream bed at the proposed axis. The dam will rest on glacial deposits of till, clay, sand and gravel, and on deposits of lake-shore and alluvial fan gravels.
\nB. Geologic conditions in the area of the right abutment, as yet imperfectly known, may make necessary a long, deep cutoff extending for an unknown distance beyond the north end of the dam.
\nC. A foundation exploration program is recommended that includes deepening test pit No. 1 and drill hole No. 2, and drilling 11 new holes. It is suggested that one drill hold near the center of the valley be taken to bedrock to give a complete picture of the fill materials underlying the foundation.

\n
\n

3. Delivery of water from the forebay of the reservoir to the powerhouse eight miles downvalley by means of a conduit is regarded as infeasible because: difficult terrain of the route will require earthwork more extensive than the volume of the dam; the route is subject to land slides, and will require expensive maintenance; it is more or less completely exposed to adverse winter conditions that may engender icing conditions; and it is easily subject to sabotage. It is recommended that the water be taken to the powerhouse through a rock tunnel.

The Rush and Brown mine and the Venus prospect are near the head of Kasaan Bay about 10 miles northwest of the village of Kasaan and about 45 miles northwest of Ketchikan, the nearest port. (See fig. 1.) They are in an area of moderate relief in in which some hills are a little more than 500 feet high. Much of the area is covered with glacial drift and dense vegetation. Muskegs are numerous. Outcrops are scarce and are confined mostly to steep slopes, stream beds, and places where development work has been done on the ore deposits. Topographic, geologic, and magnetic surveys of the vicinities of the ore deposits were made by the Geological Survey in 1943, and a brief examination of a portion of the underground workings at the Rush and Brown mine was made in 1944.

The area is underlain principally by greenstone which has been intruded by bodies of pyroxenite, gabbro, and diorite. Foliation in the greenstone is obscure. post of the intrusive bodies trend northwesterly.

The principal ore deposits are veins containing chiefly pyrite, chalcopyrite, and pyrrhotite. A few deposits of copper-bearing magnetite have been found. Most of these are small, but a larger one at the Rush and Brown mine has been mined for its copper and precious metals.
