About this map

Aleutian Range peaks and high-altitude ice define this remote section of the Kenai Peninsula, where the massive Blockade Glacier dominates the central landscape. The ice field transitions into a complex network of glacial meltwater and braided channels, most notably feeding the McArthur River as it winds through the eastern portion of the quadrangle. The map illustrates a wilderness shaped by active geological processes, showing the precise extent of the glacier's footprint and the surrounding terrain in 2016.

Surveyed at a 1:25,000 scale, this record documents the interaction between permanent ice and seasonal runoff. The township and range lines of the Public Land Survey System, including t11n r16w and t12n r17w, provide a cartographic grid over a landscape otherwise devoid of permanent human settlements or infrastructure, making it a critical reference for studying environmental change and glacial retreat in Alaska.
