Oblique aerial view of the bog-covered alluvial plain of the Nixon Fork lowland. McGrath district, Kuskokwim region, Alaska. 1949.

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.
