Geologic Mapping Projects
-
Geologic Mapping of Mount St. Helens Project
-- Wolfe, Hoblitt,
The intent of this project is to produce the first detailed (1:24,000-scale),
published geologic map of Mount St. Helens.
-
Geologic Mapping in Southern Washington Cascades Project
-- Banks, Swanson, Ashley, Moore,
The primary goal of these interlinked studies is better understanding of the Cascades arc --
how it formed, when and where it was
folded, faulted, intruded, and mineralized, and how it relates to active volcanism and
seismicity in southwestern Washington.
