Process description:
VESTRA scanned in the hard copy quad maps and digitized them into GIS.
Update 10/10/2005:  Updated location of a Large Landslide Deposit per a geotechnical report by RGH consulting which showed the location to be slightly northwest of original location.  Also changed from a Large Landslide Deposit to a Soil Slump per report.  Location is 043-061-019-000.
