2018 Map of Lake Clark D-5 SE

About this map

Lake Clark National Preserve covers the northeastern portion of this topographic study, where the tundra landscape transitions into the prominent Bonanza Hills. This area of southwestern Alaska is defined by a complex drainage system feeding into the Mulchatna River, which meanders across the northern reaches of the quadrangle. The steep, closely-spaced contours of the hills to the south contrast sharply with the wetland-dense lowlands to the north, illustrating the characteristic transition from upland ridges to river basins. Glacial and snowmelt runoff is traced through several named waterways, including Glacier Cr, Pass Cr, and Bonanza Cr. The lack of road infrastructure or established settlements emphasizes the wilderness character of this region within the Lake and Peninsula Borough, where surveying was conducted using SPOT imagery and National Hydrography Dataset records to map the remote hydrology.
