Term Deseret limestone used in favor of Pine Canyon limestone. Base of Pine Canyon as defined by Loughlin (1919) was not placed consistently at the same horizon. Because of discrepancies between definition and application to rocks mapped, the Pine Canyon abandoned. Was formerly used in the Tintic district, Juab Co, UT in the Great Basin province and in Utah Co, UT on the Wasatch uplift.
