If you’re taking a road trip through Colorado this summer, you might want to check out the Colorado Geological Survey’s Tourist Guide to Colorado Geology, brand new this year. This fun and easy-to-use map instructs tourists and visitors on the various elements of the geology of Colorado. You can learn the names and ages of different rocks and formations, as well as information on the prehistory of the area. Using this map you can also find State Parks and points of geological interest. The map might also be a helpful way to amuse the kiddies in the backseat! (“hey Junior, why don’t you count how many quartzite deposits you can spot before we stop for lunch…”) You can also find other tourist-related geological resources from the Survey, including their book Messages in Stone as well as their Field Trip Guide series, available from our library.
