Lavas and shallow intrusions near Wenatchee, WA, provide a unique opportunity to study a diverse array of samples that erupted over a 30+ Ma interval in the Cascadia rear arc. Included are two Eocene units, the Wenatchee Pinnacles and Sugarloaf Peak, two Miocene units, Eagle Rock and Burch Mountain, and an undated andesite at Peoh Point. Goals of this study are to use trace and major element data to determine the tectonic setting and petrogenesis of these rocks and identify any compositional differences between there rear-arc sites and the Cascade arc as a whole.
