1958 Map of Tyonek B-8

USGS Topo · Published 1987

About this map

North Twin Glacier and South Twin Glacier dominate this interior landscape, illustrating the massive ice formations that define the northern reaches of the Kenai Peninsula Borough. The map captures a largely unpopulated wilderness where the Skwentna River and Chilligan River carve through high alpine terrain. This area was later formally protected as part of the Lake Clark National Park and Wilderness, with the boundary line clearly established by 1980 legislation. Smaller features like Max Lake and the Harpoon Glacier provide specific orientation points for pilots and explorers navigating this roadless corridor. The convergence of the Matanuska-Susitna Borough and Kenai Peninsula Borough lines highlights the jurisdictional divisions in this remote Alaskan territory.
