Maximum sustained unit recharge for the basin was approximately 1.4 feet per day. Dur-ing 1975 a second basin of 8 acres was also used for recharge, and the total diversion rate was increased to as much as 30 cubic feet per second. The second basin was never completely filled, but the unit recharge rate was estimated to be at least four times as great as that in the first basin.</p><p>During 1973 and 1974, when only one recharge basin was in operation, a maximum rise of 18 feet was observed in the ground-water table near the basin. In 1975, when both basins were being used, the maximum rise was 30 feet in the same area. During 1973 and 1974, the water-level rise was 12 and 8 feet in the unconfined and confined systems, respectively, at a point 4.400 feet downgradient from the basins; in 1975 the rise at the same point was 31 and 16 feet, respectively.</p><p>It was originally believed that because of the location of the recharge ponds within the natural recharge zone of the area's confined aquifer system, the source of the major portion of Anchorage's public water supply, most of the artificially recharged water would enter that system. However, water-level data and changes in saturation conditions interpreted from borehole geophysical logs indicate that most of the recharged water remained in the unconfined aquifer. In addition, the potentiometric rise that was achieved in the confined aquifer during summer operation of the recharge basins was quickly dissipated when diversion stopped and the basins drained. Thus the benefits of recharge would not persist into late winter, the critical period of water availability in Anchorage, unless diversion to the basins could be continued until January or February.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri7738","usgsCitation":"Anderson, G.S., 1977, Artificial recharge experiments on the Ship Creek alluvial fan, Anchorage, Alaska: U.S. Geological Survey Water-Resources Investigations Report 77-38, Report: v, 39 p.; Plate: 16.13 x 18.21 inches, https://doi.org/10.3133/wri7738.","productDescription":"Report: v, 39 p.; Plate: 16.13 x 18.21 inches","costCenters":[],"links":[{"id":158128,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"country":"United States","state":"Alaska","city":"Anchorage","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -150.09796142578125,\n              61.018386522468596\n            ],\n            [\n              -149.52667236328125,\n              61.018386522468596\n            ],\n            [\n              -149.52667236328125,\n              61.312451574838214\n            ],\n            [\n              -150.09796142578125,\n              61.312451574838214\n            ],\n            [\n              -150.09796142578125,\n              61.018386522468596\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abbe4b07f02db672c32","contributors":{"authors":[{"text":"Anderson, Gary S.","contributorId":36534,"corporation":false,"usgs":true,"family":"Anderson","given":"Gary","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":195482,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

This hydrologic year was characterized by heavier than normal winter precipitation in California and Washington and abnormally dry winter conditions in coastal Alaska.

The metamorphic rocks include amphibolite-facies orthogneiss and paragneiss, greenschist-facies fine-grained siliceous and graphitic metasediments, and a variety of carbonate rocks. Lithologic units within the metamorphic terrane trend generally north-northeast and dip moderately toward the southeast. Thrust faults locally juxtapose lithologic units in the metamorphic assemblage, and normal faults displace both the metamorphic rocks and some parts of the granite stock. The gneisses and graphitic metasediments are believed to be late Precambrian in age, but the carbonate rocks are in part Paleozoic. Dating by the potassium-argon method indicates that the granite stock is Late Cretaceous. \r\n\r\nThe stock has sharp discordant contacts, beyond which is a well-developed thermal aureole with rocks of hornblende hornfels facies. The average mode of the granite is 29 percent plagioclase, 31 percent quartz, 36 percent K-feldspar, and 4 percent biotite. Accessory minerals include apatite, magnetite, sphene, allanite, and zircon. Late-stage or deuteric minerals include muscovite, fluorite, tourmaline, quartz, and albite. \r\n\r\nThe stock is a zoned complex containing rocks with several textural facies that are present in four partly concentric zones. Zone 1 is a discontinuous border unit, containing fine- to coarse-grained biotite granite, that grades inward into zone 2. Zone 2 consists of porphyritic biotite granite with oriented phenocrysts of pinkish-gray microcline in a coarse-grained equigranular groundmass of plagioclase, quartz, and biotite. It is in sharp, concordant to discordant contact with rocks of zone 3. Zone 3 consists of seriate-textured biotite granite that has been intruded by bodies of porphyritic biotite granite containing phenocrysts of plagioclase, K-feldspar, quartz, and biotite in an aplitic groundmass. Flow structures, pegmatite and aplite segregations, and miarolitic cavities are common in the seriate-textured granite. Zone 4, which forms the central part of the complex, consists of fine- to medium-grained biotite granite and locally developed leucogranite. Small miarolitic cavities are common within it. \r\n\r\nEight textural facies have been defined within the complex, and mineralogic, petrographic, modal, and chemical variations are broadly systematic within the facies sequence. Study of these variations shows that the gradational facies of zones l and 2 systematically shift toward more mafic compositions inward within the complex. Seriate-textured rocks of zone 3 are similar in composition to those of zone 2, but porphyritic rocks of zone 3 and rocks of zone 4 mark shifts to more felsic compositions. These late-crystallizing felsic rocks are products of an interior residual magma system. This system was enriched in water and certain trace elements including tin, lithium, niobium, lead, and zinc. The complex as a whole has higher concentrations of these elements than many other granites.

The available data suggest that this history could have included: (1) chilling and metasomatic alteration adjacent to the contact, (2) in-situ crystallization in several marginal facies accompanied by some transfer of residual constituents toward interior parts of the pluton, (3) slight upward displacement of magma that was subjacent to the crystallized walls, accompanied by disequilibrium crystallization and local vapor saturation, (4) upward displacement of part of the residual water-rich interior magma, accompanied by rapid loss of a separated vapor phase, and (5) displacement of the margins of the pluton by normal faults, accompanied by loss of an exsolved vapor phase from th","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr7735","usgsCitation":"Hudson, T., 1977, Genesis of a zoned granite stock, Seward Peninsula, Alaska: U.S. Geological Survey Open-File Report 77-35, xv, 188 p. :ill., maps (1 fold. in pocket) ; scale 1:31,680; 28 cm., https://doi.org/10.3133/ofr7735.","productDescription":"xv, 188 p. :ill., maps (1 fold. in pocket) ; scale 1:31,680; 28 cm.","costCenters":[],"links":[{"id":151857,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1977/0035/report-thumb.jpg"},{"id":48947,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0035/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":48948,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1977/0035/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"scale":"31680","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b24e4b07f02db6aebcf","contributors":{"authors":[{"text":"Hudson, Travis","contributorId":90282,"corporation":false,"usgs":true,"family":"Hudson","given":"Travis","affiliations":[],"preferred":false,"id":180978,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Field-study methods were of a reconnaissance nature, and thus the interpretations in the report are tentative. \r\n\r\nLandscape of the Metlakatla Peninsula, on which the city of Metlakatla is located, is characterized by a muskeg-covered terrane of very low relief. In contrast, most of the rest of Annette Island is composed of mountainous terrane with steep valleys and numerous lakes. During the Pleistocene Epoch the Metlakatla area was presumably covered by ice several times; glaciers smoothed the present Metlakatla Peninsula and deeply eroded valleys on the rest. of Annette Island. The last major deglaciation was completed probably before 10,000 years ago. Rebound of the earth's crust, believed to be related to glacial melting, has caused land emergence at Metlakatla of at least 50 ft (15 m) and probably more than 200 ft (61 m) relative to present sea level.\r\n\r\nBedrock in the Metlakatla area is composed chiefly of hard metamorphic rocks: greenschist and greenstone with minor hornfels and schist. Strike and dip of beds are generally variable and minor offsets are common. Bedrock is of late Paleozoic to early Mesozoic age. Six types of surficial geologic materials of Quaternary age were recognized: firm diamicton, emerged shore, modern shore and delta, and alluvial deposits, very soft muskeg and other organic deposits, and firm to soft artificial fill. A combination map unit is composed of bedrock or diamicton. Geologic structure in southeastern Alaska is complex because, since at least early Paleozoic time, there have been several cycles of tectonic deformation that affected different parts of the region. Southeastern Alaska is transected by numerous faults and possible faults that attest to major movements of the earth's crust. The latest of the major tectonic events in the Metlakatla region occurred in middle Tertiary time; some minor fault activity probably continues today at depth. Along the outer coast of southeastern Alaska and British Columbia, major faulting activity occurs in the form of active, strike-slip movement along the Queen Charlotte fault about 100 mi (160 kin) west-southwest of Metlakatla. Some branching subsidiary faults also may be active, at least one of which may be the Sandspit fault. \r\n\r\nMany major and smaller earthquakes occur along the outer coast. These shocks are related to movements along the Queen Charlotte fault. A few small earthquakes occur in the region between the outer coast and the Coast Mountains, which includes Metlakatla. 0nly a few earthquakes have been reported as felt at Metlakatla; these shocks and others felt in the region are tabulated. Historically, the closest major earthquake was the magnitude 8.1 Queen Charlotte Islands earthquake of August 22, 1949, which occurred along the Queen Charlotte fault 125 mi (200 km) southwest of Metlakatla. No damage was reported at Metlakatla. The probability of destructive earthquakes affecting Metlakatla is unknown. A consideration of the tectonics and earthquake history of the region, however, suggests that sometime in the future an earthquake with a magnitude of about 8 will occur along that segment of the Queen Charlotte fault nearest to Metlakatla. Smaller earthquakes with magnitudes of 6 or more might occur elsewhere in the Metlakatla region or south-southeastward near Dixon Entrance or Hecate Strait. \r\n\r\nSeveral geologic effects that have characterized large earthquakes elsewh6re may be expected to accompany some of the possible major earthquakes that might affect the Metlakatla area in the future. Evaluation of effects indicates that fault displacement and tectonic uplift or subsidence are probably unlikely, and ground shaking in general probably would be strongest","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr77272","usgsCitation":"Yehle, L.A., 1977, Reconnaissance engineering geology of the Metlakatla area, Annette Island, Alaska, with emphasis on evaluation of earthquakes and other geologic hazards: U.S. Geological Survey Open-File Report 77-272, iv, 93 p. :maps (4 fold.) ;28 cm.; (2 sheets, scale 1:9,600; 2 sheets, scale 1:25,000 - PGS), https://doi.org/10.3133/ofr77272.","productDescription":"iv, 93 p. :maps (4 fold.) ;28 cm.; (2 sheets, scale 1:9,600; 2 sheets, scale 1:25,000 - PGS)","costCenters":[],"links":[{"id":95023,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0272/plate-01.pdf","size":"494","linkFileType":{"id":1,"text":"pdf"}},{"id":95024,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0272/plate-02.pdf","size":"674","linkFileType":{"id":1,"text":"pdf"}},{"id":95025,"rank":402,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0272/plate-03.pdf","size":"542","linkFileType":{"id":1,"text":"pdf"}},{"id":95026,"rank":403,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0272/plate-04.pdf","size":"906","linkFileType":{"id":1,"text":"pdf"}},{"id":95027,"rank":404,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0272/plate-05.pdf","size":"1561","linkFileType":{"id":1,"text":"pdf"}},{"id":95028,"rank":405,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0272/plate-06.pdf","size":"441","linkFileType":{"id":1,"text":"pdf"}},{"id":95029,"rank":406,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0272/plate-07.pdf","size":"542","linkFileType":{"id":1,"text":"pdf"}},{"id":95030,"rank":407,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0272/plate-08.pdf","size":"305","linkFileType":{"id":1,"text":"pdf"}},{"id":95031,"rank":408,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0272/plate-09.pdf","size":"285","linkFileType":{"id":1,"text":"pdf"}},{"id":95032,"rank":409,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0272/plate-10.pdf","size":"224","linkFileType":{"id":1,"text":"pdf"}},{"id":144982,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1977/0272/report-thumb.jpg"},{"id":39664,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1977/0272/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"scale":"9600","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a74e4b07f02db6442c3","contributors":{"authors":[{"text":"Yehle, Lynn A. yehle@usgs.gov","contributorId":3794,"corporation":false,"usgs":true,"family":"Yehle","given":"Lynn","email":"yehle@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":163717,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
