2021 Map of Mount Shasta

About this map

Mt Shasta and its satellite peak Shastina dominate this 2021 topographic survey, revealing the intricate glacial systems of the high Cascades. The map details the expansive ice fields of the Whitney Glacier, Hotlum Glacier, and Bolam Glacier, which define the northern and eastern flanks of the volcanic massif. Lower elevations within the Shasta National Forest show a landscape shaped by water and gravity, from the steep walls of Diller Canyon to the thermal activity at Sulphur Springs. Historical transit corridors are marked by Military Pass in the northeast, while high-altitude basins like Hidden Valley and water bodies such as Clarence King Lake illustrate the alpine hydrology of the region. The survey provides precise contouring for mountaineering landmarks including Casaval Ridge, Red Banks, and Thumb Rock.
