Stratigraphy
Formation:Lodgepole
Stratigraphy comments: The Mississippian rocks in the Chesterfield Range consist of Lodgepole limestone overlain by a 1900ft. limestone-sandstone sequence here designated the Chesterfield Range Group. The lower terrigenous part, about 965 ft. thick is the Little Flat Fm., it has a basal siltstone member, a middle sandstone member, and an upper sandy limestone member. The upper part of the Chesterfield Range Group, here named the Monroe Canyon Limestone is about 925 ft. thick and contains a lower massive member and a medial medium-bedded member, and an upper cherty member. The range stretches northwest from Soda Springs, Idaho. It is an eastern dipping block of Paleozoic strata irregularly overlapped by the Tertiary Salt Lake Fm.
Lithology and environment
Primary lithology:shelly/skeletal "limestone"
Lithology description: The Lodgepole consists of about 260 ft. of thin to nodular bedded fine-grained limestone with several massive, coarse-grained crinoidal limestone layers. These coarse-grained beds are more common near the base and top of the formation.
