1958 Map of Kenai D-8

About this map

Lake Clark Pass serves as the focal point of this 1950s era survey, illustrating a critical natural corridor through the Alaska Range. The geography is defined by high-altitude ice and glacial runoff, with the Alta Glacier feeding into the surrounding drainage systems. The Tlikakila River and the Glacier Fork carve distinct paths through the steep terrain, while Summit Lake sits prominently near the height of the pass. This document reflects the landscape as it was recorded shortly before the formal establishment of conservation boundaries, which were later superimposed as the Lake Clark National Park and Lake Clark Wilderness. The mapping captures the precise flow of the North Fork Big River and the untouched nature of the Kenai Peninsula’s interior, offering a technical view of the region's hydrology and topography.
