Title

Locating the pebble dikes in Little Cottonwood Canyon

Abstract

    Pebble dikes are tabular, brecciated bodies composed of multiple large clasts surrounded by a fine-grained matrix. (Johnson) Such formations found in Draper, Utah appear to contain clasts from the Little Cottonwood Stock (LCS) and the White Pine Intrusion (WP), which are located approximately 17 km north-east of the pebble dikes current location.
    Following instructions given by Bryon J. Sharp’s 1958 paper on igneous rock bodies in Little Cottonwood Canyon a pebble dike was found near the Little Cottonwood Creek. Clasts of LCS and White Pine Intrusion can easily be seen and identified in the dike. 
    The similarities between the dike found in Little Cottonwood Canyon and the dikes found in Draper indicate that they are the same feature. This discovery supports the hypothesis that the Traverse Mountain Block slid from its position over the Little Cottonwood Stock in a catastrophic landslide
