Album caption: Exposure of till and outwash of the Kobuk Glaciation along the east bank of the Ambler River. Stratified yellowish-gray gravel, sand, and silt in the upper part of the bluff overlies bluish-gray till in the lower part. The 100-foot section was measured near the left side of the picture. The bluff is 2 miles upstream from the junction of the Ambler and Kobuk Rivers. Kobuk district, Northern Alaska region, Alaska. 1951. Published as figure 2 in U.S. Geological Survey Bulletin 1181-K. 1964. No index card available.

Album caption: Vertical aerial view of stable dune field, with locally active dunes, near the Little Kobuk Sand Dunes. Small active dunes (smooth white areas) and many swamps and ponds are scattered over the area. The active dune near the center of the pictue is part of a large and complex blowout, characterized by canoe-shaped troughs and broadly accurate longitudinal ridges. The dune-building winds are southeast to east. The dune field is about 5 miles south of the Kobuk River, midway between Nakochelik and Mishuk Creeks. Kobuk district, Northern Alaska region, Alaska. 1951. (Photo by U.S. Coast and Geodetic Survey) Published as figure 4 in U.S. Geological Survey Bulletin 1181-K. 1964. No index card available.

Album caption: Oblique aerial view of the outer and inner moraines of the Farewell glaciation along the South Fork. The fresh inner moraine (Qdf2) of the Farewell glaciation (Farewell 2) is at the left of the picture, and the slightly subdued outer moraine (Qdfl) of the same glaciation (Farewell 1) in the middle and right foreground. Outwash (Qof) of this glaciation leads away from these moraines and forms a smooth, fairly steep slope at their immediate front and a gentle slope away from them. A segment of the greatly subdued moraine (Qds) of the Selatna glaciation can be seen in the right background. This segment, and a part of the outer moraine of the Farewell glaciation, are pictured on the right and left sides,...

Album caption: Oblique aerial view of the Takotna River valley and the bordering uplands. The flood plain of the meandering Takotna River (Qam) floors of the broad canyon cut through the uplands along the Nixon Fork fault. On the left side of the river, Takotna Mountain rises about 3.500 feet above sea level. It has a core of mafic and felsic igneous rocks of Tertiary age and is mantled with rubble. To the right of the river are rounded mountains and creek valleys underlain by folded sedimentary rocks - graywacke and shale - of Cretaceous age. The summits form a prominent upland surface that has been intensely dissected by streams. McGrath district, Kuskokwim region, Alaska. 1942. (Photo by U.S. Army Air Force)...

Album caption: Vertical aerial view of the eastern half of the Little Kobuk Sand Dunes. The dune field at the left of the picture, in part stabilized and in part active, becomes increasingly active toward the right where it merges into the Little Kobuk Sand Dunes. On the left a series of U-shaped dunes form large parabolic ridges with long gently curved sides; in the active field they form undulating transverse ridges with ends at the edge of the field curved back to the windward. The dune-building winds are southeasterly. Kobuk district, Northern Alaska region, Alaska. 1951. (Photo by U.S. Coast and Geodetic Survey) Published as figure 5 in U.S. Geological Survey Bulletin 1181-K. 1964. No index card available.

Album caption: Vertical aerial view of part of the younger dune field bordering the Kuskokwim River. Prominent dune ridges in the field (Qs) are outlined and numbered as follows: (1) single ridges, (2) composite ridges, and (3) groups of ridges. The dune field is bordered on the northeast by the flood plain (Qam) of the meandering Kuskokwim River, from which it is separated by a steep escarpment that averages 100 feet in height. Along this border there is also a low bedrock hill (a.) Center of the picture is located about 8 miles east-southeast of McGrath. McGrath district, Kuskokwim region, Alaska. 1942.

Album caption: Oblique aerial view of the bog-covered alluvial plain of the Nixon Fork lowland and bordering fan apron. The bog-covered alluvial plain (Qapl) covers much of the upper half of the picture. The bogs (a) smooth light-gray areas, and islands (b) together give a ragged, mottled appearance to the picture. On the lower half is a fan apron (Qaa) that leads down from bordering uplands and merged into the alluvial plain. The flood plains (Qam) of the Nixon Fork and one of its tributaries are along the upper edge of the picture. McGrath district, Kuskokwim region, Alaska. 1949. (Photo by U.S. Air Force) Published as figure 34 in U.S. Geological Survey Bulletin 1071-G. 1960. No index card available.

This exposure is 6 miles southwest of Lone Mountain. McGrath district, Kuskokwim region, Alaska. circa 1949. Published as figure 24 in U.S. Geological Survey Bulletin 1071-G. 1960.
