This map represents the results of our attempt to unify the surficial geology and geomorphology of Clark County as expressed in available digital data sources spanning most of the county. Much work remains to be done to fully unify the various sources, but this is a big step.
Soon we will develop a 'postable' figure showing our interpretations of the published data that were unified, thus explaining the colors on the map. In the example above, the bedrock is not shown (note that the dark green is vegetation indicated on the base map).

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.
