The data include concentrations of major inorganic constituents, nutrients, selected trace metals, total organic carbon, and chlorophyll. Vertical profiles of specific conductance, temperature, dissolved-oxygen saturation, and pH were drawn. With the exception of Redoubt Lake, all of the lakes are very similar chemically. The small differences in chemical composition probably reflect variations in geology of the drainage basins, altitudes, and morphometric characteristics of the lakes. Productivity is so low in all the lakes that it was not possible to rank the lakes by relative productivity from the reconnaissance sampling. Redoubt Lake is meromictic, but the others are probably holomictic and dimictic.

No surface evidence was found to indicate that any of the faults have been active in Holocene time. The sparse shallow seismicity thus far recorded does not correlate with known faults, nor does it define linear trends suggestive of faulting. Tidal flats at the mouths of the Kenai, Kasilof, and Chickaloon Rivers have been uplifted in the Holocene, however, and the uplift may reflect growing anticlines at depth. Some faults associated with folding may be active, but they are probably too limited in size to generate destructive earthquakes. They could, however, constitute a hazard to manmade structures in their immediate vicinity.</p><p>Vibrational damage and ground failure during the 1964 earthquake were most extensive north of Tustumena Lake in areas of water-saturated unconsolidated deposits with uneven topography. South of Tustumena Lake, damage resulted mainly from landslides formed along unconfined bluffs and riverbanks, and from submarine sliding and subsidence at Homer Spit. A comparable distribution of surficial effects may be anticipated in future large earthquakes on the Kenai Lowland.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr76270","usgsCitation":"Tysdal, R.G., 1976, A preliminary evaluation of selected earthquake-related geologic hazards in the Kenai Lowland, Alaska: U.S. Geological Survey Open-File Report 76-270, 30 p., https://doi.org/10.3133/ofr76270.","productDescription":"30 p.","costCenters":[],"links":[{"id":419222,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1976/0270/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":153481,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1976/0270/report-thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Kenai Lowland","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -151.87245003265602,\n              61.20124766870401\n            ],\n            [\n              -151.87245003265602,\n              60.02668659471945\n            ],\n            [\n              -150.02753847212168,\n              60.02668659471945\n            ],\n            [\n              -150.02753847212168,\n              61.20124766870401\n            ],\n            [\n              -151.87245003265602,\n              61.20124766870401\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1fe4b07f02db6aacf1","contributors":{"authors":[{"text":"Tysdal, Russell G.","contributorId":1700,"corporation":false,"usgs":true,"family":"Tysdal","given":"Russell","email":"","middleInitial":"G.","affiliations":[],"preferred":true,"id":184066,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The Yakataga Formation, with an aggregate outcrop thickness of about 5,000 m, is characterized by variable amounts of distinctive neritic marine tillite-like diamictite and laminated siltstone containing dropstones interpreted as ice-rafted glacial debris. The lithology, sedimentary structures and molluscan fauna of the formation suggest that active tidal glaciers or an ice shelf were present along the landward margin of the basin possibly beginning in early or early middle Miocene time. Dropstone distribution in outcrop sections indicates that glaciers reached tidewater intermittently during the Miocene and were almost continuously present throughout the Pliocene and much of the Pleistocene. Paleomagnetic and nannoplankton dating of the upper 1,181 m of the Yakataga Formation at Middleton Island indicate that this part of the sequence probably was entirely deposited during the Matuyama reversed polarity epoch of the Pleistocene during which the sedimentation rate was of the order of 1 m/1,000 years.&nbsp;</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr7684","usgsCitation":"Plafker, G., and Addicott, W.O., 1976, Glaciomarine deposits of Miocene through Holocene age in the Yakataga Formation along the Gulf of Alaska margin, Alaska: U.S. Geological Survey Open-File Report 76-84, 36 p., https://doi.org/10.3133/ofr7684.","productDescription":"36 p.","costCenters":[],"links":[{"id":418977,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1976/0084/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":149012,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1976/0084/report-thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Gulf of Alaska","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -149.84105802510388,\n              60.02848768166979\n            ],\n            [\n              -149.84105802510388,\n              57.84995795947654\n            ],\n            [\n              -138.59679213263794,\n              57.84995795947654\n            ],\n            [\n              -138.59679213263794,\n              60.02848768166979\n            ],\n            [\n              -149.84105802510388,\n              60.02848768166979\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abee4b07f02db674ea8","contributors":{"authors":[{"text":"Plafker, George","contributorId":3920,"corporation":false,"usgs":false,"family":"Plafker","given":"George","email":"","affiliations":[],"preferred":false,"id":171154,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Addicott, Warren O.","contributorId":80668,"corporation":false,"usgs":true,"family":"Addicott","given":"Warren","email":"","middleInitial":"O.","affiliations":[],"preferred":false,"id":171155,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Beginning in 1927, the placers were worked for 7 years by small-scale mining methods; in later years dragline excavators and a dredge were utilized. These deposits are important, not only because they are of high grade but because they are the only commercial source of platinum metals in the United States.&nbsp;</p><p>The bedded rocks of this area are sedimentary and volcanic rocks of late Paleozoic(?) age that have been intruded by a variety of ultrabasic rocks. The platinum metals of the placers have been derived from a mass of dunite and related rocks that constitute the bedrock of Red Mountain in the upper valley of the Salmon River. The western headwater tributaries of this stream are the fluvial conduits that have produced all the placers in the valley of the river.</p><p>The principal placers lie in two pay streaks, one in the valley floor of the Salmon River and the other in an ancient stream channel along the east side of this valley. The stream-channel deposit, called the bench pay streak, was formed in early Pleistocene time; its alluvial materials consist largely of clay derived from an ancient moraine believed to be of Nebraskan age. The valley-floor deposit, called the pay streak of the valley floor, consists of alluvial materials of fluvial and glaciofluvial origin whose ages range from Yarmouth to Holocene. Both channels contain high-grade placers that have yielded a large volume of platinum metals.</p><p>The platinum metals of these deposits are contained mainly in two alloys intergrown in a pseudoeutectic fabric. The major alloy is mainly platinum, with a small amount of iridium, still smaller amounts of rhodium and palladium, and probably some osmium and ruthenium. The minor alloy is dominantly iridium and osmium with less platinum and still less ruthenium and rhodium. The compositions of these two alloys are somewhat variable but tend to approach constant mean values. A small amount of free gold is recovered with the platinum metals. In addition to these two alloys, minute amounts of five platinum minerals have been identified. The weighted mean percentages of platinum, iridium, osmium, ruthenium, rhodium, palladium, and gold, as mined from 1936 to 1972, are respectively 82.25, 11.32, 2.15, 0.17, 1.30, 0.38, and 2.43.</p><p>The lodes from which these placers have been derived are, or have been, localized in the Red Mountain ridge, where the principal rocks are dunite and serpentinite. No lodes have been recognized, either because the platinum metals are sparsely distributed or because a large part of the platiniferous rock has been eroded. It is known, however, that the amounts of iridium, osmium, and ruthenium, or of osmiridium, decrease from south to north. Other generalizations regarding the composition and granularity of these metals have been deduced. The size and shape of the platinum lodes may have ranged from diffuse disseminations to high-grade concentrations in small loci. Under certain assumptions, the tenor of platinum metals in the dunite can be roughly approximated. Utilizing two totally different methods of computation, the mean tenor has been estimated to lie between 0.19 and 0.27 grain of platinum metals per cubic yard of dunite, or 0.014 to 0.023 gram per stere. No large low-grade deposits of commercial value are likely to be found, but it is possible that some small high-grade concentrations occur.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/pp938","usgsCitation":"Mertie, J.B., 1976, Platinum deposits of the Goodnews Bay district, Alaska: U.S. Geological Survey Professional Paper 938, iv, 42 p., https://doi.org/10.3133/pp938.","productDescription":"iv, 42 p.","costCenters":[],"links":[{"id":486535,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_5112.htm","linkFileType":{"id":5,"text":"html"}},{"id":418479,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/pp/0938/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":140358,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/pp/0938/report-thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Goodnews Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -162.94921875,\n              59.84481485969105\n            ],\n            [\n              -161.8505859375,\n              59.84481485969105\n            ],\n            [\n              -161.8505859375,\n              60.413852350464914\n            ],\n            [\n              -162.94921875,\n              60.413852350464914\n            ],\n            [\n              -162.94921875,\n              59.84481485969105\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad9e4b07f02db684f72","contributors":{"authors":[{"text":"Mertie, John Beaver Jr.","contributorId":91093,"corporation":false,"usgs":true,"family":"Mertie","given":"John","suffix":"Jr.","email":"","middleInitial":"Beaver","affiliations":[],"preferred":false,"id":152192,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Postglacial accumulation of peat, commonly 5 to 10 feet thick, and the presence of ground water at or very near the surface combine to create the swamp-muskeg terrane of much of the area. Deeper, confined ground water is also present beneath thick silt and clay layers that underlie the surficial deposits. Domestic water supply for the lowland lakes area is provided largely by public-supply wells completed in the deep, confined aquifers. No large perennial streams traverse the area, thus streamflow is not a major parameter in the area 's natural water balance. The major uses of surface water are recreational, including fishing and boating at several of the larger lakes, and private and commercial aircraft operations at Hood-Spenard Lakes floatplane base. The hydrology and water balance of these lakes is complex. Water levels in some lakes appear to be closely related to adjacent ground-water levels. Other lakes are evidently perched above the local water table. The relation of lake level to adjacent ground-water level may vary along the shoreline of a single lake. The effect of residential development practices on lake basin water balance is not completely understood.

The mineralized areas occur in syenite and appear to be concentrated along the margins of alkaline dikes, with allanite tentatively identified as the principal mineral containing the uranium-, thorium-, and rare-earths. Samples contain as much as 0.15 percent U<sub>3</sub>0<sub>8</sub> and 1.05 percent Th0<sub>2</sub>, and over 2 percent rare-earth elements. These mineralized rocks&nbsp;are closely associated with alkaline dikes which are part of a dike swarm that crops out over at least 250 km<sup>2</sup> (100 mi<sup>2</sup>). This large dike swarm is thus of considerable economic interest.</p><p>These uranium-, thorium-, and rare-earth-rich rocks occur near the west end of the western Alaska uranium-thorium province (West, 1953; Clark and others, 1975; Miller, 3976) and were found during a regional investigation of this province by the Geological Survey. The alkaline dikes were known from previous mapping by the two senior authors (Miller and others, 1972) to be anomalously radioactive. The mineralized areas described in this report were found while making a brief study of (1) alteration and/or mineralization associated with these dikes and (2) their relation to similar dikes and rocks which occur elsewhere in the province (Miller, 1972).</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr76710","usgsCitation":"Miller, T.P., Elliott, R.L., Finch, W.I., and Brooks, R.A., 1976, Preliminary report on uranium-, thorium-, and rare-earth-bearing rocks near Golovin, Alaska: U.S. Geological Survey Open-File Report 76-710, 13 p., https://doi.org/10.3133/ofr76710.","productDescription":"13 p.","costCenters":[],"links":[{"id":419018,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1976/0710/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":143415,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1976/0710/report-thumb.jpg"}],"country":"United States","state":"Alaska","city":"Golovin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -163.04503433922062,\n              64.55597714768643\n            ],\n            [\n              -163.04503433922062,\n              64.53575301654521\n            ],\n            [\n              -162.98275431696564,\n              64.53575301654521\n            ],\n            [\n              -162.98275431696564,\n              64.55597714768643\n            ],\n            [\n              -163.04503433922062,\n              64.55597714768643\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b06e4b07f02db69a150","contributors":{"authors":[{"text":"Miller, Thomas P. tmiller@usgs.gov","contributorId":4183,"corporation":false,"usgs":true,"family":"Miller","given":"Thomas","email":"tmiller@usgs.gov","middleInitial":"P.","affiliations":[{"id":121,"text":"Alaska Volcano Observatory","active":false,"usgs":true}],"preferred":false,"id":158950,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Elliott, Raymond L.","contributorId":82667,"corporation":false,"usgs":true,"family":"Elliott","given":"Raymond","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":158953,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Finch, Warren I.","contributorId":91923,"corporation":false,"usgs":true,"family":"Finch","given":"Warren","email":"","middleInitial":"I.","affiliations":[],"preferred":false,"id":158952,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Brooks, Robert A.","contributorId":60645,"corporation":false,"usgs":true,"family":"Brooks","given":"Robert","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":158951,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Diagenetic alteration of framework grains throughout the stratigraphic sequence has produced widespread zeolite cement or phyllosilicate grain coatings and pseudomatrix. Multiple deformation and deep burial of the older Tertiary sequence--the Orca Group, the shale of Haydon Peak, and the Kulthieth and Tokun Formations--caused extensive alteration and grain interpenetration, resulting in low porosity values. Less intense deformation and intermediate depth of burial of the younger Tertiary sequence--the Katalla, Poul Creek, Redwood, and Yakataga Formations--has resulted in a greater range in textural properties. Most sandstone samples in the younger Tertiary sequence are poorly sorted, tightly packed, and have strongly appressed framework grains, but some are less tightly packed and contain less matrix. Soft and mineralogically unstable framework grains have undergone considerable alteration, reducing pore space even in the youngest rocks. \r\n\r\nMeasurements of porosity, permeability, grain density, and sonic velocity of outcrop samples of the younger Tertiary sequence indicate a modest up-section improvement in sandstone reservoir characteristics. Nonetheless porosity and permeability values typically are below 16 percent and 15 millidarcies respectively and grain densities are consistently high, about 2.7 gm/cc. Low permeability and porosity values, and high grain densities and sonic velocities appear to be typical of most outcrop areas throughout the onshore Gulf of Alaska Tertiary Province.","language":"ENGLISH","publisher":"U.S. Dept. of the Interior, Geological Survey,","doi":"10.3133/ofr76198","usgsCitation":"Winkler, G., McLean, H., and Plafker, G., 1976, Textural and mineralogical study of sandstones from the onshore Gulf of Alaska Tertiary Province, southern Alaska: U.S. Geological Survey Open-File Report 76-198, iii, 48 leaves :ill., map ;27 cm.; (51 p., 6 sheets - PGS), https://doi.org/10.3133/ofr76198.","productDescription":"iii, 48 leaves :ill., map ;27 cm.; (51 p., 6 sheets - PGS)","costCenters":[],"links":[{"id":150179,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1976/0198/report-thumb.jpg"},{"id":45597,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1976/0198/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad5e4b07f02db683737","contributors":{"authors":[{"text":"Winkler, Gary R.","contributorId":75513,"corporation":false,"usgs":true,"family":"Winkler","given":"Gary R.","affiliations":[],"preferred":false,"id":173125,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McLean, Hugh","contributorId":73977,"corporation":false,"usgs":true,"family":"McLean","given":"Hugh","affiliations":[],"preferred":false,"id":173124,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Plafker, George","contributorId":3920,"corporation":false,"usgs":false,"family":"Plafker","given":"George","email":"","affiliations":[],"preferred":false,"id":173123,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

These lineaments occur as alinements of surface geologic structures, linear valleys or ridges, and linear changes in tonal contrast marking differences in soil type, soil moisture, or vegetation. The lineaments are believed to represent the surface traces of zones of weakness deep within the earth's crust along which vertical or horizontal adjustments to earth stresses persistently recurred since at least Precambrian time.</p><p>A consistent pattern in the lineaments can be discerned in Alaska (fig. 1D), and throughout the North American Cordillera (fig. 2). This pattern is believed to represent a mosaic of crustal blocks, whose differential movements have guided the tectonic development of the Cordillera.</p><p>Areas in which mineral deposits are known to be concentrated are alined along many of the lineaments or occur at lineament intersections, suggesting that the zones of weakness reflected by the lineaments provided felicitous pathways for upward movement of mineralizing agents. Other lineaments bound areas of high mineral concentration suggesting that some crustal blocks have had a tectonic history more favorable for mineralization than others. These conclusions suggest that the study of space image lineaments can provide new and fruitful approaches to the search for concealed mineral deposits.</p><p>In Alaska, some lineaments coincide in part with active fault traces and some separate areas of significantly different structure and geologic history. However, the movements along the zones of weakness which these lineaments are believed to reflect have been too slow and spread over too many millions of years for the lineaments to be considered as marking zones of present earthquake hazard.</p><p>Detailed discussion of the lineaments, and of interpretations as to their meaning, are contained in: 1) a paper presented by Lathram and Raynolds at the First William T.

One additional site was put under surveillance in 1976. Except for construction changes wrought by installation of the pipeline, most of the sites surveyed showed very little change since the 1975 surveys. Some of the significant events of 1976 at the monitored crossing sites include: glacier-dammed lake break-out floods on the Tazlina and Tsina Rivers, severe icings on the Gulkana River which resulted in a spring flood 3-4 feet (1 meter) over banktop, and virtual completion of all the buried crossings and all but one overhead crossing before the 1976 channel erosion resurveys were made.</p><p>Aerial photogrammetric surveys were used again in 1976 on the same seven sites as in 1975. Comparison of the photogrammetric surveys with each other and with on-the-ground surveys indicate that the method is generally applicable for channel erosion studies. However, it requires engineering judgement and personal knowledge of the site to avoid reaching inaccurate conclusions about channel change in some instances.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr77170","usgsCitation":"Doyle, P.F., and Childers, J.M., 1976, Channel erosion surveys along TAPS route,
