D. Cultural
Data of surficial geology and geomorphology compiled for specific sites to study the
relationship between erosion patterns and preservation of archeology sites.
2. Historical photographs - locations, dates, and descriptions of features found in the
subject photograph assembled into a georelational data base.
3. Campsite delineation - polygons delineated around often-used campsites to serve as
baseline data for long-term monitoring.
APPLIED RESEARCH
Four studies were chosen to be highlighted in this paper because they represent established
contributions to the long-term monitoring work and research efforts associated with GCES in
the Grand Canyon.
The first study was presented by the NAU (Northern Arizona University) Department of
Geology. NAU developed an innovative approach to study sandbar aggradation and depletion
using the GCES/GIS data base in conjunction with a hypsometric analysis.
