Larger-scale maps


The objective of this work is the preparation of geologic maps at the 1:50,000 or larger scale for areas of the State where population growth, resources, and environmental concerns are most critical or where detailed geologic mapping is required to solve regional geologic problems. Large-scale maps are also completed with EDMAP support.
