Map Description:
This is the map of soil organic matter derived from the national STATSGO database which was developed by the Natural Resources Conservation Service. The color scale ranges from gray sandy soils to dark brown loamy organic peats. Again the midwest stands out, and so does the Okefenokee swamp in south Georgia and the Everglades of Florida.

Taken from the report:
A New High-Resolution National Map of Vegetation Ecoregions Produced Empirically Using Multivariate Spatial Clustering by William W. Hargrove and Robert J. Luxmoore
