Geologic maps and rockhounding maps
Maps to show you the different geologic strata beneath your feet, or maps to tell you were to look to collect rocks and minerals.
Our geologic maps delineate rock formations on maps of the entire US or regional areas. Most of these are geologic highway maps, so you'll know what type of geology the highway you are traveling on goes through.
Rockhounding maps help rockhounds and other rock and mineral collectors find good locations to hunt for interesting speciments.
