    Cover: View eastward from the trail to Swiftcurrent Pass, Glacier National Park, Montana. The lake in the foreground is Bullhead Lake. The greenish-gray–colored unit forming the lower part of the mountainside in the distance is the Appekunny Formation. Above it is the Grinnell Formation which is maroon-colored, and the overlying tan-colored unit forming the ridge to the left is the Helena Formation. See “Sedimentation, earthquakes, and tsunamis in a shallow, muddy epeiric sea: Grinnell Formation (Belt Supergroup, ca. 1.45 Ga), western North America” by Pratt and Ponce, p. 1411–1439.
