Mount Shasta’s summit is 14,162 feet above the sea, but from about 12,000 ft. level the terrain is covered with perpetual
snow and rock and circled by five large glaciers which are situated by the points of the compass from the summit rocks as
follows: North slope, has Hotlum and Bolam glaciers, East slope has Wintoon glacier, West slope has Whitney glacier, and the
South slope has Konwakiton glacier, which is popularly known as Mud Creek or McCloud glacier, as it is the source of the McCloud
In the winter of 1924, because of the light snowfall the glaciers were free of snow by the first of May, and commenced to
melt and discharge large streams of water. Since the melting was mainly along the sides, the water ran under the ice and soon
formed channels and undermined the foundations of the Mud Creek Glacier. By the end of June the bodies of ice commenced to
break off at the lower ends and falling some hundreds of feet carried great masses of rock sand and gravel with them.
Observers stated that with sounds like the discharge of cannon, masses as large as an ordinary house would break off every
two or three minutes and away they would go down the canyon. The resultant avalanches wrecked the McCloud water system, and
made a great slope of glacial sand some seven miles long and a mile or more wide, with a depth of from five to thirteen feet
and discolored the McCloud, the Pit and the Sacramento Rivers for miles from their sources.
Collection is open for research without restriction.
Scope and Contents note
This collection contains correspondence with W.B. Cook dated January 17, 1941, a bibliography of related resources, 1 map

All photographs were taken September, 1924. Included in the photographs are 4 enlargements that create a panorama of Mud Creek
Canyon - north wall of Mud Creek Canyon. All of the photographs have been cataloged and given a sc number, except for three.

Processing Information note
Processing of the Mud Creek Glacier Photo Album was generously funded by the Andrew W. Mellon Foundation, and administered
by the Council on Library and Information Resources (CLIR). The [ABC repository] was awarded a Cataloging Hidden Special Collections
and Archives grant from 2010-2012, "Uncovering California's Environmental Collections," in collaboration with eight additional
special collections and archival repositories throughout the state and the California Digital Library (CDL). Grant objectives
included processing of over 33 hidden collections related to the state's environment and environmental history. The collections
document an array of important sub-topics such as irrigation, mining, forestry, agriculture, industry, land use, activism,
and research. Together they form a multifaceted picture of the natural world and the way it was probed, altered, exploited
and protected in California over the twentieth century. Finding aids are made available through the Online Archive of California
The library can only claim physical ownership of the collection. Users are responsible for satisfying any claimants of literary
