This map was funded by the National Cooperative Geologic Program as part of the geologic mapping studies conducted along the I-70 urban corridor. This corridor is experiencing rapid urban growth and geologic mapping is needed to aid in land-use planning in order to address, avoid, and mitigate known and potential geologic hazards.
