About this map

The Amphitheater Mountains dominate this 1949 topographic landscape, a high-altitude wilderness where glacial action carved deep basins like Sevenmile Lake and Landmark Gap Lake. The terrain is characterized by a complex network of waterways, including the Maclaren River and the southern extent of the Tangle Lakes system, including Upper Tangle Lake and Round Tangle Lake.

Infrastructure is limited to the Denali Highway, which traverses the center of the sheet, crossing through Maclaren Summit. This route provides a rare corridor of access through the high tundra, passing notable geographic markers such as Whistle Ridge and the broad expanse of High Valley. The map records a moment before extensive modern development, documenting the raw topography of the Matanuska-Susitna Borough and the precise drainage patterns of glacial valleys like Tarn Valley and Houseblock Valley.
