Edgecumbe 2002. View NNE of summit of Edgecumbe cone in foreground, crater of Crater Ridge domes in background. Dark reddish layers on Edgecumbe are dacitic pumice of early post-glacial pyroclastic episode; dark gray layers beneath, on left, are andesitic ash/pumice of the same episode, some of which originated at andesitic plug just visible at left side of crater. All rhyolitic ash/pumice of this pyroclastic episode originated at Crater Ridge crater, some of which came out as pyroclastic flows or lahars and ran into the sea both to the right (east) and left (west) of the crater.
