USGS TRAIL MOUNTAIN, COLORADO Geologic Map, COLORFUL MAP 1974 - FOSSIL LOCATIONS

Description

SCARCE ITEM!!
This is USGS map GQ-1156,
Geologic Map of the Trail Mountain Quadrangle, Grand County, Colorado.
Published in 1974, this is a nice item depicting the interesting geology of this area. This 7.5-minute quadrangle map is quite colorful, and really would look nice f
ramed.
Formations range in age from Triassic through Mesozoic to Tertiary and include a wide range of rock types, mostly various
sedimentary
rocks and volcanic rocks, but some intrusive rocks are also present. Apiatan Muountain is at the north end of the map. Willow Creek Reservoir is in the south center part of the map. Much of the area is in the Arapaho National Forest.
Some gold placers exist in this area and are mentioned in a short article on the map.
The Pierre shale is present in the area and is noted for collections of fossils, including ammonites, that are discussed on the map and precise locations are shown with symbols on the map.
All in all, this is a cool, colorful map that would look great on the wall of a home or business in the area, or just kept for study and enjoyment. This would be a great guide to the geology in this pretty area. Good for any hikers, local residents or mineral collectors and fossil collectors looking to score a new location.
I have other Colorado area maps listed, so check my other items.
