Abstract

The AA. describe rock glaciers and Matthes-age (Little Ice Age) moraines in the Sierra Nevada, and discuss their formation, extent, and climatological significance. They conclude for the Sierra that most valley-floor rock glaciers (i.e., tongue-shaped rock glaciers) and many Matthes moraines are ice-cored and glacial in origin. Matthes and Recess Peak ELA (equilibrium-line altitudes) gradients along the crest evidently depend strongly on local orographic effects rather than latitudinal climatic trends, indicating that simple linear projections and regional climatic interpretations of ELA gradients of small glaciers may be unreliable
