| Description |
Hot springs travertine from the Holocene of Wyoming, USA. (6.6 cm across at its widest) Travertine is a crystalline-textured, chemical sedimentary rock composed of calcium carbonate (calcite). It forms principally in cave environments and is the most common variety of speleothem (stalactites, stalagmites, etc.). Travertine also forms at some springs, either hot springs or cold springs. This sample is from a weathered, extinct hot spring travertine mound on the western margin of Wyoming's Rattlesnake Mountain Uplift (a.k.a. Rattlesnake Mountain Anticline). The uplift is part of a extensive set of mountain ranges from New Mexico to western Canada that were formed during the Laramide Orogeny (late Mesozoic to mid-Cenozoic). Other inactive hot springs travertine mounds occur on the eastern side of the uplift. Nearby, some active hot springs occur on the western side of the town of Cody. Most hot springs travertine samples are significantly vuggy, as is this specimen. The prominent horizontal structures is the impression of a plant that originally grew in the active hot spring site - some plants can tolerate such conditions. Locality: float from roadcut on the northern side of Rt. 16 / 20, just west of third tunnel west of Cody, next to Buffalo Bill Reservoir, central Park County, northwestern Wyoming, USA (44° 30' 04.65" North latitude, 109° 11' 027.28" West longitude) |
