VllNorthern California through Oregon and Washington to British Columbia. The intellectual scope was as broad and interdisciplinary as possible, with participants representing the fields of geology, heat flow, seismology, igneous petrology, hydrology, electromagnetic geophysics, magnetics, water geochemistry, gravity, paleomagnetism, and tectonics.The conference was organized around three major themes:Variations in tectonics, geophysical signature, and magmatism along the length of the Cascade volcanic arc.Relationship of the Cascade Range to the subduction tectonics to the west and to the continental tectonics to the east. Controls on the location, composition, and rates of magmatism in the Cascade Range. The 35 attendees were almost equally divided between USGS scientists and scientists from other research institutions, including universities, other federal agencies, state agencies, Canada, and Japan.This Redbook contains nearly all the presentations made at the 01-04 December 1988 Conference in Monterey. We do not intend or imply that it is the final word on the Cascade Range.Instead, its purpose is to release promptly the material presented at the December 01-04 Conference to other concerned investigators and to the public.Accordingly, we have not attempted to edit the contributions, even lightly. It is our plan, however, that each of the authors will revise his/her Redbook contribution in view of the other contributions and that the resultant papers will form the nucleus of a reviewed and edited special section of the Journal of Geophysical Research, hopefully to be published within the year.
