Photographed in Derby Canyon near Peshastin, Washington, I believe this is the Showy or Royal Penstemon, Penstemon speciosus, though I have trouble with some of them in telling them apart. Derby Canyon is one of many rather dry sandstone canyons in the area that have an amazing flora and are well worth exploring.
