COVER EXPLANATION.—Wind-driven waves break on the pumice beach of June Lake, Inyo National Forest, California. The winnowing action of the waves leaves coarser sediments on the shoreline, while fine silts and biogenic oozes accumulate in the deepwater depocenters of this glacial scour lake. Basin morphology, orientation, and bathymetry are dominant controls on these modern sedimentary processes. Carson Peak looms in the background (Photo by Mike McGlue). See Lyon et al., this issue.
