About this map

Chekok sits along the northern shores of Iliamna Lake, serving as a focal point for this mid-century survey of the Alaska Peninsula. The landscape is defined by the intersection of deep freshwater bays and high peaks, including the prominent Knutson Mountain and Pedro Mountain. Drainage patterns are clearly marked by the winding courses of Chekok Creek and Canyon Creek, which feed into the extensive bay system.

Remote waterways like Lower Tazimina Lake and Chekok Lake illustrate the glacial geography of the region before significant modern development. The map details several coastal features such as Chekok Point and a series of islands including Hat Island, Grassy Island, and Porcupine Island. This survey captures the traditional land-water relationship of the Pedro Bay area, documenting the shoreline as it existed during the mid-1950s field annotations.
