Abstract

Colluvial boulder fields are ubiquitous on desert hillslopes in the Basin and Range Province. Five chronometric methods indicate that colluvial boulder fields in this region have been active in the late Pleistocene and Holocene. A new method is presented to constrain the ages of colluvial boulder fields, using the presence of stable rock varnish and [36]Cl. Rather than interpreting colluvial deposits from the traditional desert geomorphology framework of relict or active, the AA. suggest that these features be studied from the perspective of ongoing processes using an independently established chronometric sequence
