Mount Saint Helens stands at the center of this survey, revealing the post-eruptive landscape decades after the 1980 event. The topographic detail focuses on the massive 1980 Crater and its central Lava Dome, where the Crater Glacier is shown developing within the blast zone. This geological record traces the immediate hydrologic and glacial recovery of the mountain, from the The Breach on the north face down to the Pumice Plain.
