Geologic Map of West Virginia. West Virginia's geologic history stretches back into the Precambrian, and includes several periods of mountain building and erosion. At times, much of what is now West Virginia was covered by swamps, marshlands, and shallow seas, accounting for the wide variety of sedimentary rocks found in the state, as well as its wealth of coal and natural gas deposits.
Loss of life from alluvial fan floods continued into the 19th century, and the hazard of alluvial fan flooding remains a concern in Italy. [61] On January 1, 1934, record rainfall in a recently burned area of the San Gabriel Mountains, California, caused severe flooding of the alluvial fan on which the towns of Montrose and Glendale were built ...
Ice Mountain is a mountain ridge and algific talus slope [4] that is part of a 149-acre (60 ha) preserve near the community of North River Mills in Hampshire County, West Virginia, United States. It was designated a National Natural Landmark in 2012.
Alluvial fan – Fan-shaped deposit of sediment; Anabranch – A section of a river or stream that diverts from the main channel and rejoins it downstream. Arroyo – Dry watercourse with flow after rain; Asymmetric valley – Valley that has steeper slopes on one side; Backswamp – Environment on a floodplain where deposits settle after a flood
An alluvial fan could have been deposited and formed outside of a mountain range, however, thrusting of the mountain belt could cause the alluvial fan to become broken up by the new mountain forming. Thus, the alluvial fan would be split with the fan on either side of the new mountain range development and could change the steepness of the fan. [1]

Viewers sent photos from other places in West Virginia as well. Although most of the accumulation was limited to mountain peaks, areas near Tucker County High School saw some snow sticking on the ...
The Catskill was once considered to be related to the Old Red Sandstone, but in actuality, the two are only coincidentally similar. Both formed at approximately the same time, and under similar conditions: to the north of the Acadian Mountains were the Caledonian Mountains, and a similar region of marsh and river delta formed there.
