I have a grad student look for GIS datasets for the land use (current and historic) and stratigraphic data for the areas listed above.  I suspect this might be proprietary but I'm not sure. We have books on the stratigraphy of the area and I referred her to the Perry-Castenada collection for possible maps. 

Any help would be appreciated.  Our library hasn't purchased any datasets and I honestly am not sure what's available..

Thanks
