This web presentation is an overview of the material covering the glacial history of Mount Shasta. Surprisingly few academic papers have been published regarding this topic. The scarcity of publications about glaciation on Mount Shasta is mostly because Holocene volcanic deposits cover much of the Pleistocene and early Holocene glacial deposits, but the fact that Mount Shasta is not located close to major universities is also a contributing factor. Most of the information presented below is gleaned from local papers and materials available in the Mount Shasta Collection of the College of the Siskiyous library. There is a host of photographs in the collection which will be of value to those who can interpret them.
