Abstract
This paper discusses the timing, processes, and nature of shelter deposits, and their relationships to climatic conditions during the Late Holocene at Boren Shelter No. 2 in Garza County, Texas. Sedimentation within the shelter is characterized by granular disintegration of the sandstone walls and ceiling, spalling of larger clasts (rockfall), and colluvial and eolian deposition of externally derived sediments. The occurrence of granular disintegration and rockfall appears to be independent of climatic conditions; however, the deposition of colluvial and eolian sediments appears to be a response to climatic changes on the Southern Plains during the second millennium AD.
