Form a panorama of Big Horn Hot Spring, Thermopolis; looking east across Big Horn River and the terraces of travertine to the "Red Beds' which are inclined southward on the flank of a sharp anticline whose apex lies to the left. From this anticline 18,600,000 gallons of sulphur water issues every 24 hours, having a temperature of 135 degrees F, and carrying calcium carbonate and other mineral matter in solution. In the distance in order from left to right, are the older Chugwater red beds, the Alcova marine limestone, gypsum and shale of the upper part of the Chugwater, the marine Sundance formation, (the basal sandstone is absent here), the Morrison formation and the sandstone correlated with the lower sandstone...

Down the canyon of Middle Fork of Popo Agie River, near Lander; showing walls composed of hard layers of limestone and sandstone ranging in age from Cambrian to Permian. The prominent ledge at the skyline is composed of sandstone and limestone of Pennsylvania age. Photos lwt228a, lwt2288b and lwt2288c form this panorama. Fremont County, Wyoming. 1922. Plate 5-A in U.S. Geological Survey. Professional paper 149. 1927.

Limestone near the base of the "Red Beds" overlying red shale at the west end of Casper Mountain: fossils of Permian age were found here. These beds have been provisionally correlated with the Forelle limestone and Satanka shale. Natrona County, Wyoming. 1922. Plate16-A in U.S. Geological Survey. Professional paper 149. 1927.

North face of Goose Egg Mountain, near Casper; showing the light colored rocks in the lower part of the "Red Beds" the Embar of the oil men; evenly bedded overlying the red bed of the Chugwater formation in the steep slope; the ledge of Alcova limestone, which contains fossil invertebrates of probable Triassic age; and the younger formations up to early Cretaceous, which forms the crest. Natrona County, Wyoming. 1922. Plate 19-B, with graphics, in U.S. Geological Survey. Professional paper 149. 1927.

Alcova limestone southeast of Alcova; a near view of the limestone on North Platte River, showing details of bedding, where invertebrates of probable Triassic age were found in it. Natrona County, Wyoming. 1922. Plate 21-B in U.S. Geological Survey. Professional paper 149. 1927.
