Weather, Caves

A cave is a natural opening in the ground extending beyond the zone of light and large enough to permit the entry of man. Occurring in a wide variety of rock types and caused by widely differing geological processes,

caves range in size from single small rooms to interconnecting passages many miles long. The scientific study of caves is called speleology (from the Greek words spelaion for cave and logos for study). It is a composite science based on geology, hydrology, biology, and archaeology.

Cowboy Caves, located on the Colorado Plateau in Utah, are named for the cowboy graffiti and cattle brands scratched on the walls in relatively recent times. But they have provided archaeologists with a wealth of information about prehistoric life in the region as well.

The caves show signs of human occupation beginning about 6,300 years ago, including fire pits, milling stones, grass matting, rock art, and unusual split-twig figurines. BLM.
