Abstract

Analysis of 690 asymmetric ripple mark and 40 cross-stratification paleocurrent directions from 37 localities in the Red Peak Formation indicates three major current directions: northeast, southwest, and northwest. They are interpreted respectively to represent wave drift, rip, and longshore currents moving on, off, and along a northwest-southeast oriented coast. Visual interpretation of the plotted patterns was used; vector analyses techniques were inadequate. Evidence suggests that symmetrical and asymmetrical ripple marks are not wave- and current-formed respectively, but rather, since all are somewhat asymmetrical, are due to currents (and waves in shallow water) alone.
