A recent increase in dirt mapper activityhas resulted in a collective dataset covering ~75% of the county. These data from USGS and NBMG sources are presently being unified into a single classification scheme based on common process, material, and geochronologic characteristics. We will soon post the unifying scheme for comments.
We also are pursuing a couple of leads that include mapping of the remaining part of the county. We currently have our hands on a hard copy of a generalized bedrock map of Southern Clark County that we know will suit our needs well.
