The area covered extends along the front of the range from Sagavanirktok Lake (68°28' N. - 149°25' W.) west to the head of the Kukpowruk River (68°25' N. - 162°40' W.). The southernmost point in the area is at the head of Alapah Creek (68°11' N. - 150°40' W.) and the northernmost point is on Lisburne Ridge just west of the Etivluk River (68°36' N. - 156°40' W.).
Field work was done by the authors at Sagavanirktok Lake, Kanayut Lake, Alapah Creek, the Anaktuvuk and Tiglukpuk Creek, and Chandler Lake. Brief visits were made to the Lisburne Ridge just north and west of the junction of the Nigu and Etivluk Rivers and to outcrops of Lisburne limestone along the Kiligwa River (68°30' N. - 158°35' W.). Data from other areas included in this report were collected by other field parties of the U. S. Geological Survey. A. L. Bowsher, Sr. .and J. T. Dutro, Jr. studied the Lisburne limestone at Kanayut Lake, Nanushuk Lake, and Itkillik Lake in 19491/ .W. W. Patton, Jr. and Irving L. Tailleur described the Lisburne limestone exposed in the northern Brooks Range along the Kiruktagiak River 2/ and the Okokmilage River 3/ in1949, and I. L. Tailleur and Bion H. Kent have supplied data on the Etivluk-Kiligwa Rivers area from their field work of 1950 4/. R. M. Chapman, G. D. Eberlein, and C. D. Reynolds measured sections of Lisburne limestone at Kurupa Lake and on the east fork of the Etivluk River in 1950 5/. E. G. Sable and M. D. Mangus measured the section on Iligluruk Creek near the head of the Kokolik River in 1950 6/,, and Chapman end Sable measured the section at the head of the Kukpowrok River in 1949 7/.
Structural and stratigraphic studies of the rocks in the Siksikpuk and Nanushuk Rivers area were conducted by Navy Oil Unit party No. 2 during the summer field season of 1950. The field party consisted of six men: two geologists; two field assistants; a cook; and a weasel mechanic. Three weasels were used for transportation of equipment and personnel.
The area examined covers approximately 1;000 square miles of the Arctic Foothills province and lies between the Itkillik River on the east and the Chandler River on the west. The area is drained by the Nanushuk, Anaktuvuk, Siksikpuk; and Chandler Rivers.
The mapped area adjoins the Okpikruak and Kiruktagiak Rivers area1/ to the west.
The primary objective of the geologic work in this area was detailed stratigraphic study of pre-Nanushuk group rocks in the Southern Foothills belt as a supplement to the work begun in the Okpikruak and Kiruktagiak Rivers area in 1949. A secondary objective was areal mapping and structural studies for the purpose of delimiting structures favorable for drilling tests of the Lisburne limestone.
Parts of this area had been reconnoitered by members of the U. S. Geological Survey in previous years. In 1901 F. C. Schrader traversed the Anaktuvuk River, In 1945 R. E. Fellows, R. M. Chapman, and C. T. Bressler visited outcrops along the northern margin of the area in the vicinity of the Anaktuvuk River and Kanayut Creek, E. J. Webber and R. L. Detterman examined a few of the cutbanke along the Nanushuk River in 1947 and in 1949. A. L. Bowsher, Sr.; and J, T. Dutro mapped an outlier of Lisburne limestone north of Nanushuk Lake during the 1949 field season.

S. Geological Survey Navy Oil Unit Party I examined the surface geology of the area of the upper Utukok River and east fork of the Kokolik River from June 28 to September 3, 1950. The party consisted of six men: E. G. Sable and M. D. Mangus, geologists; C. L. Hummel and F. H. Shannon, field assistants; R. D. Gerard, cook; and L. E. Hall, weasel mechanic. Three weasels were used for transportation in the field.
The area examined approximates 1,000 square miles and is in the extreme southwest corner of Naval Petroleum Reserve No. 4. It is bounded on the west by Iligluruk Creek (east fork of the Kokolik) and on the east by Driftwood Creek. With the exception of Driftwood Creek, major streams were ascended to their headwaters in the De Long Mountains. A traverse southward over the Utukok-Kugururok Rivers divide was successfully completed, providing a \"tie-in\" with the work of Navy Oil Unit Party 7. Several traverses were made 8 miles north of the Driftwood anticline and to the west fork of the Colville River.
The objectives of this part of the summer's work were (1) the geologic mapping and stratigraphic study of the rocks exposed in this area, and (2) measurement of stratigraphic thicknesses of sediments older than those exposed in the Driftwood anticline. Geology was plotted on vertical and trimetrogon oblique aerial photographs. Altitudes were established by altimeter traverses.
The northern part of this area was previously investigated by members of the Navy Oil Unit. In 1947 R. M. Thompson and W. L. Barksdale1/ visited outcrops along the Utukok River, and in 1949 R. M. Chapman and E. G. Sable2/ examined exposures along the Kokolik River. (See fig. 1, index map.)

The accompanying diagram (Fig. 1) presents a generalized stratigraphic picture of the section that would be penetrated by a hole located on the crest of each of these structures. The zonal thicknesses, as shown in this diagram, are average figures and they probably vary from anticline to anticline within this area as they do elsewhere on the North Slope. The thickness of postulated favorable sands and also the stratigraphic horizon reached by each of the proposed 1,500-foot holes may be further affected by the postulated prezone F unconformity. It seems probable that zone E is essentially absent at Umiat. At the Weasel Creek anticline a total of approximately 1,700 feet of zone E sediments appear to be present. This is probably the complete zone E section. Thus the thickness of zone E sediments m4y vary considerably from place to place within the area west of Umiat covered by this report, and these possible variations are not shown in the diagram (Fig. 1). Interpretations of depth and thickness of favorable sands are based on the facies studies of T. G. Payne1/.
Discussions presented are limited to Nanushuk Group rocks and no reference is made nor inference intended as to possible favorable stratigaphic or structural conditions in the older sedimentary rocks.

Field mapping of the Aupuk anticline began on August 1, and about 1 month was devoted to the study. Party personnel consisted of G. Donald Eberlein and Charles D. Reynolds, geologists, W. L. D'Olier and W. D. Carter, field assistants, Richard Olson, camp cook, and Max H. Davis, weasel mechanic. Robort M. Chapman, geologist, visited the party for 1 week early in August to help start the work and shared, with Eberlein, the responsibilities associated with the final compilation of this report.
Three weasels were used for daily transportation to the field and for moving camp. A 10-foot Link boat equipped with 5 hp. outboard motor was used to cross the Colville River. As field work progressed from west to east it became apparent that the camp equipment and weasels would have to be gotten across the Colville River if field work was to be completed by early September. This crossing was effected without incident at a point approximately 10 miles below the confluence of the Kurupa and Colville Rivers on August 26. The party reached Umiat on September 5.

These tests were drilled in an attempt to determine the origin of the Simpson oil seeps and to evaluate the petroleum possibilities of the area. These holes failed to satisfy the objective for which they were drilled, but did define a nearly north-south linear ridge of essentially unconsolidated sand enclosed by a monotonous sequence of clay shale. A gas-bearing horizon and good oil shows were encountered on the crest of the ridge in the vicinity of Seep No. 2 during the 1949 drilling season. In November 1949 the Operating Committee approved the drilling of additional core holes in this area to resolve the complex geologic problems encountered by the shellow drilling of the previous season. Four additional tests had been completed by November 1, 1950, and a fifth is now in progress. Drilling completed thus far in 1950 has resulted in more accurate delineation of the sand ridge, and a flowing oil well has been discovered on the west edge of the ridge near Seep No. 3.

Zones B and C are not differentiated in mapping and description. South of the Meade River 2,100 feet of zones B-C and 1,500 feet of zone D are exposed. North of the fault zone along the Meade River, the only rocks present, estimated not over 1,000 feet thick, are zone D beds which may be at least in part younger than the zone D rocks south of the Meade River. Sands which barely meet the minimum requirements for potential reservoir beds are present in both zones.
South of the Meade River the Kigalik anticline and the Falcon Creek anticline, both sharp-crested folds, trend east. The intervening synclines are broad with low dips on the flanks. Along the Meade River the major structure is a zone of reverse faults, about three-fourths of a mile wide, which brings rocks of zones B-C on the south opposite rocks of zone D on the north. Minimum displacement in this zone is 1,000 feet at longitude 157° 50'W. and 300 feet near the gas-seep lake. North of the fault zone, the Meade River anticline is a rather low fold, so poorly exposed that closure cannot be detected by surface geologic methods.

The party consisted of six men: two geologists, two field assistants, a weasel mechanic, and a cook. Three weasels were used for transportation in the field.
The area covered is bounded on the west by the Okpikruak River, on the east by the Chandler River, and on the south by the north front of the Brooks Range. Tuktu Bluff on the Chandler River and its westward extension forms the northern boundary. The area is drained by the Chandler, Kiruktagiak, Ayiyak, Okokmilaga, and Okpikruak Rivers.
The objectives of this summer's work was the geologic mapping and stratigraphic study of the rocks that crop out in this area. All outcrops were visited and the geology was plotted on vertical and trimetrogon oblique aerial photographs. Altitudes were established by an altimeter traverse.
Parts of this area had been investigated previously by members of the Navy Oil Unit. During the summer of 1945 George Gryc, E. J. Webber, and Karl Stefansson visited outcrops along the. Chandler and Kiruktagiak Rivers and in the vicinity of Castle Mountain.
In the same year L. A. Warner and C. E. Kirschner examined outcrops along the Okpikruak River in conjunction with their survey of the Klink and Colville Rivers. R. L. Detterman included detailed stratigraphic studies of cutbanks near the confluence of the Kiruktagiak and Chandler Rivers in his geological mapping of the lower Chandler during the summer of 1948.
