About this map

The Chickaloon Glacier and Talkeetna Glacier dominate this 1950s study of the high Talkeetna Mountains. Based on 1949 aerial photography and 1951 field annotations, the map reveals a wilderness landscape defined by extensive ice fields and the headwaters of glacial-fed drainages. The Chickaloon River flows southward through the center of the sheet, carving a deep valley that contrasts with the high, unnamed peaks and ridges surrounding it.

Smaller watercourses like Clear Creek and Caribou Creek trace the drainage patterns of this unsurveyed territory. The map is particularly notable for its depiction of glacial recession and drainage morphology before significant modern changes, providing a primary record of the Seward Meridian high country as it appeared in the mid-20th century. For those studying the glacial history of the Matanuska-Susitna region, it offers precise topographical data on permanent ice structures and their associated tributary streams like Glass Creek and Moss Creek.
