... Fort Union Formation, 4,000 feet (1,219 m) thick only 7 miles (11.3 km) to the east, was completely eliminated from the local surface stratigraphy by that means. The northern end of Bald Ridge is formed by the highly asymmetric Canyon Mouth anticline. That structure differs strongly in the attitude...

..., the route turned west again, across Snowdrift Mountain to the head of Georgetown Canyon. Snowdrift anticline forms the crest of the mountain, and is flanked by the Webster and Georgetown synclines. The Brazer limestone of Mississippian age is exposed at the apex of the anticline and is flanked by the Wells...

.... The parautochthon, itself, is in the upper plate of the Absaroka-St. Johns thrust system with several lesser thrusts between. Folds in the study area are confined to individualthrust plates and are given local names. Most of these follow Mansfield (1952) with the exception of his “Snowdrift anticline” which here...

... Lake County, Idaho ( Figs. 2 , 3 ). An almost complete sequence of allochthonous Mississippian rocks is exposed in the core of a northward-plunging anticline on the north side of the Meade overthrust, overlying parautochthonous Jurassic rocks. The Mission Canyon Limestone and Lodgepole Limestone were...

.... A synorogenic conglomerate which was almost certainly derived from a hanging-wall anticline in the “early Absaroka thrust” contains identifiable clasts of upper Lower Cretaceous Aspen Shale, whereas shaly interbeds higher in the same unit have mid-Santonian microfossils. Clearly, that unit is post-Early...

...; the South Arch, Cedar Creek anticline, folding in the Big Snowy basin and other features took place at this time. Of particular interest is whether or not the tectonism in Montana produced a regional unconformity between Meramecian and Lower Mississippian strata. The upper Mission Canyon locally...

... anticlinal uplifts and upthrusts at places in the western parts of the region where Mesozoic sediments, and especially Cretaceous sediments were not deposited, were thinly deposited, or were eroded. The result is that burial of the Permian strata lessened within short distances to the east. In contrast...
