1960 Map of Anchorage A-5

About this map

Upper Lake George and Lake George dominate this glacial corridor within the eastern reaches of the Chugach National Forest. Photogrammetric methods from 1957 aerial photography reveal a landscape defined by massive ice flows, including the Colony Glacier and the Surprise Glacier. The map documents the intricate network of crevasses and ice fields that feed into the Twentymile River system. The presence of an indefinite boundary and the transition between the national forest and Chugach State Park underscore the remote nature of this wilderness during the mid-twentieth century. Geographic features like Whiteout Glacier and Stairway Glacier highlight the significant glaciology of the Anchorage area borough, while isolated water bodies like Glenn Lake offer landmarks for navigators in an era before modern infrastructure reached these high elevations.
