Dwight R. (Dwight Raymond) Crandell

Dwight R. Crandell was an American geologist whose long career with the U.S. Geological Survey focused on the geology of the western United States, especially volcanic landscapes in Washington. Publications available through the USGS show that he studied subjects ranging from regional and surficial geology to landslides, avalanches, and volcanic deposits.

He is especially remembered for research on Mount St. Helens and other Cascade volcanoes. Work he coauthored on the hazards of future eruptions at Mount St. Helens helped document that the volcano had a dangerous eruptive history and could erupt again, making his research an important part of the scientific groundwork for later hazard awareness in the region.

Crandell also published on Mount Rainier and related volcanic hazards, reflecting a career devoted not just to describing landscapes but to helping people understand the risks they carry. Reliable portrait imagery could not be confirmed from the sources reviewed, so no profile image is provided.
