Wilmarth, M.G., 1936, [Selected Geologic Names Committee remarks (ca. 1910-1937) on Cenozoic rocks and sediment of the western U.S.], IN Wilmarth, M.G., 1938, Lexicon of geologic names of the United States (including Alaska): U.S. Geological Survey Bulletin, 896, pts. 1-2, 2396 p.


Summary:

A name that has been applied by some geologists to the stock of granodiorite (of Late Cretaceous, or early Tertiary age) that crops out just east of Alta, in central Wasatch Mountains, Salt Lake County, Utah. (See F.F. Hintze, 1913, New York Acad. Sci. Ann., v. 23, p. 85-143). As there is only one granodiorite in the region, the USGS has not adopted a geographic name for the rock, but uses the term "Alta stock" for the structural feature which it forms.
