Worked on ARC GIS and added seven strata layers to Skyline Rim Quadrangle map. Added elevation tables, added strata tables, and also added geologic time tables into GIS database files. Finalized first map of historic water flow patterns of the original sea bed that existed before cross cutting erosion began. I am applying the laws of superposition and cross cutting relationships to place the next seven layers into correct order and elevations. The ARC GIS map is around 65% completed, but will need a couple of more weeks to complete all 8 layers of the project.
