About this map

Shamrock Glacier and Blockade Glacier define this high-altitude landscape within the Kenai Peninsula Borough, as recorded in this 2017 study by the U.S. Geological Survey. The terrain is characterized by steep elevation changes and the massive glacial flows of the Tanaina Glacier, which dominate the southwestern corner of the quadrangle.

This topographical record illustrates the intricate drainage patterns and glacial boundaries within the Public Land Survey System grids of t12n r20w, t12n r19w, t11n r20w, and t11n r19w. The survey provides a precise account of the glacial margins and high-mountain contours during the early twenty-first century, serving as a baseline for tracing the movement and extent of these ice fields in the Alaskan wilderness.
