Quick Summary

Talus caves are geological formations created by openings between boulders that have accumulated on mountain slopes. While most talus caves are small in both length and cross-section, some can be quite extensive, featuring interconnected passages. These caves are formed by the mechanical movement of bedrock and the debris from erosive processes. Notable examples of large talus cave systems can be found among granite blocks in New York and New England, with mapped passages extending for several kilometers.1
