The database for the 1:100,000-scale Valle 30' x 60' quadrangle map was compiled from 32 1:24,000-scale maps. For clarity at 1:100,000-scale, some of the units shown on the 1:24,000-scale maps were grouped together (see attached list) and some structural data were dropped; the database from the 1:24,000-scale maps is embedded in the 100,000-scale database. This database is provided here in a large compressed file; valle_db.zip (44.7 MB).
The Valle metadata report describes both 1:100,000- and 1:24,000-scale map elements. Users can view metadata either embedded within the geodatabase or in ascii format outside the database.
The authors have generated geologic maps in PDF format of each of the 32 1:24,000-scale quadrangles. To view a 1:24,000-scale geologic map, click on a quadrangle in the index map below.
