Ingrichuak Hill dominates the central landscape of this western Alaska study, rising from a complex network of wetlands and tundra within the Kusilvak Census Area. The terrain is characterized by the intricate hydrography typical of the Yukon-Kuskokwim Delta, where the winding Tunurokpak Channel and the narrow Igrikchum Slough dictate the movement of water across the flats. This 2020 map documents a transition zone where higher elevations like Ingrichuak Hill provide rare topographic relief in a region otherwise defined by sea-level drainage patterns and alluvial features.
