Leaving your pet in a closed vehicle during the warm summer days could spell disaster. Open windows and check on them often.

Railroad workers played a major role in the discovery of fossils from the Green River Formation. In the late 1860's, Union Pacific workers uncovered the first major fossil fish beds (Lake Gosiute) near the town of Green River, Wyoming.
