Mount Shasta

Mount Shasta stands 14,179 feet in Northern California, the most voluminous stratovolcano in the Cascade Range and one of the largest volcanoes in the world by sheer mass. It is a compound volcano, built from overlapping cones, the most prominent being the satellite peak Shastina on the western flank, itself a mountain-sized formation at over 12,000 feet. Seven named glaciers cling to the upper slopes, remnants of far larger ice fields that once covered the mountain.

This map reveals the double-coned structure that sets Shasta apart. The contour lines form two distinct concentric patterns, one around the main summit and one around Shastina, merging on the western slopes into a single enormous base. The glacial valleys of Whitney and Bolam glaciers cut deep notches into the north face, while the Hotlum Glacier on the northeast, the largest in California, shows as a broad depression in the otherwise tightly packed contours.
