The volcanic (~45-10 Ma) and plutonic rocks (~37-12 Ma) comprising the Western Cascades extend from northernmost California to southern British Columbia and are ancestral to modern arc magmatism. The ancestral arc hosts a series of small plutons that are locally associated with porphyry (Cu-Mo) and epithermal (Au) ore deposits. Three...

OBJECTIVE: Multidimensional Treatment Foster Care (MTFC) has been found to reduce delinquency among girls in juvenile justice through 2-year follow-up. Given that such girls are at elevated risk for suicide and depression into adulthood, we tested MTFC effects on long term trajectories of suicidal ideation and depressive symptoms.
METHOD: Girls...

Floods and ensuing damage have always been a problem for man.
Initial reaction to the frequent destruction was to avoid siting
permanent domiciles on flood-prone lands. As a result of increasing
population and pressure for development, flood control structures
were built. Instead of reducing flood losses, however, flood control
