Thursday Daily Feed, September 6, 2018, Geomorphology

September 6, 2018
Greetings and Welcome to the Daily Rock and Mineral Feed.  This will consist of a daily (well – not always) compilation of decent photos of interest.
from Geomorphological Features.
These are the images that appeal to my sensibilities or the lack thereof.
>  per Wikipedia.  “Geomorphology (from Ancient Greek: γῆ, , “earth”; μορφή, morphḗ, “form”; and λόγος, lógos, “study”) is the scientific study of the origin and evolution of topographic and bathymetric features created by physical, chemical or biological processes operating at or near the Earth’s surface. Geomorphologists seek to understand why landscapes look the way they do, to understand landform history and dynamics and to predict changes through a combination of field observations, physical experiments and numerical modeling. Geomorphologists work within disciplines such as physical geography, geology, geodesy, engineering geology, archaeology, climatology and geotechnical engineering. This broad base of interests contributes to many research styles and interests within the field.”

4.  The Velodrome is a large recumbent fold spilled southward, formed at the end of the Tertiary (23 to 5 million years) at the Alpine front. It consists of sedimentary series composed mainly of sand, sandstone and conglomerate produced by erosion of the Alps.

7. The angular unconformity at the town of Cody, Wyoming, along the Shoshone River. The overlying rocks are the Quaternary Cody Terrace Gravels. The underlying rocks dip to the east and are the Late Permian Park City Formation (siliceous carbonates & tan-gray shale) and the Early Triassic Dinwoody Fm. (tan-gray-red siltstone, gypsum, & dolomite). Neither of these formations are very thick, and the overlying red Triassic Chugwater Fm. can be seen down at the bend in the river.
