The USGS conducted a seismic-refraction survey in south-central Alaska in June and July, 1984, in order to develop velocity models along transects (1) in the Chugach Mountains, within the Chugach terrane, (2) on the Glenn Highway west of Glenallen, within the Peninsular-Wrangellia composite terrane (see Jones and others, 1981 for a dewscription of tectono-stratigraphic terranes in Alaska), and (3) along the Richardson Highway from a point east of Valdez to the Denali fauilt crossing the Border Ranges fault terrane boundary. This experiment is part of a continuing investigation designed to characterize deep crustal structure along a transect extending north from the Gulf of Alask to Prudhoe Bay.
