|Unit Name History:
Named (Cross and Howe, 1905). Revised, divided into Halgaito Tongue (base), Cedar Mesa Sandstone Member, Organ Rock Tongue, White Rim Sandstone Member (Baker and Reeside, 1929). Areal limits (Wood and Northrop, 1946). Revised, raised to group rank (Wengerd and Matheny, 1958). Revised (Shoemaker and Newman, 1959; Stewart, 1959). Overview (Baars, 1962). Mapped 1:24k in southeast Ouray Co, CO (Luedke, 1972). Revised, "lower Cutler beds" applied to rocks formerly assigned to upper Elephant Canyon Formation (Loope and others, 1990). Overview (Condon, 1992). Note that "Cutler" is not used by the USGS, but the name is recognized by the Utah Geological Survey and is widely cited in literature about the Canyonlands National Park region (see Baars, 2000).
