2019 Map of Lime Hills D-4 NW

USGS Topo · Published 2019

About this map

The North Fork Big River meanders across this wilderness quadrangle in the Bethel Census Area, illustrating a landscape defined by glacial outwash and braided water systems. This 2019 survey documents a region devoid of permanent settlements or infrastructure, where the terrain is dominated by the broad valley of the river and its tributary, the Lyman Fork. The mapping of townships t22n r28w and t21n r28w reveals the complex hydrologic patterns of the subarctic, showing how seasonal flows shape the drainage basins. For researchers, this sheet provides a high-resolution view of the native topography and watercourses before significant anthropogenic change or modern climate-driven shifts in river morphology.
