2020 Map of Saint Michael A-4 SW
USGS Topo · Published 2020About this map
Okshokwewhik Pass cuts through a dense network of wetlands in this coastal Alaska landscape, where the shifting boundaries of the Yukon-Kuskokwim Delta are defined by slow-moving water. The area is dominated by an intricate system of sloughs and passes, most notably Apoon Pass and Apakshau Slough in the southeast. These waterways surround Pieneluk Island, a landform shaped by the surrounding Pieneluk Slough and Kaweohnak Slough. The topographic data reveals a nearly level terrain where subtle elevation changes dictate the flow of the delta's distributaries. This 2020 survey provides a modern record of this fluid environment, useful for understanding the hydrography of the Kusilvak Census Area.
