Correlation of Stratigraphic Units of North America (COSUNA) Documentation Records for Southern Arizona and Vicinity

The first five stratigraphic columns of the COSUNA chart, SSMC, were constructed to show correlations of stratigraphic units in Southern Arizona, and in the Big Hatchet Mountain Area, just across the border into New Mexico. The construction of the chart was under the supervision of Frank E. Kottlowski, and authors of the columns prepared individual data sheets for each of the stratigraphic units that appears in the geological columns. This is a presentation of the documentation records prepared by the authors of the first five columns of the chart. Contributing authors of the columns were: G. Haxel, R. A. Knepp, S. J. Reynolds, S. Thompson III, and J. Wright. The COSUNA project was under the direction of Orlo E. Childs.
