Larry Henderson (park superintendent), Bob Valen, Brent Wauer, and Roger Reisch, Guadalupe Mountains National Park, supported the project and made all park facilities available to the authors. Elevations for the trail markers were surveyed by Thomas Rohrer (Queen, New Mexico), John Ames, Clifton Neeley, and Don Bebout (Bureau of Economic Geology, The University of Texas at Austin), and the markers were installed by Park Service personnel. The low-altitude, oblique aerial photographs were taken by Jerry Lucia and Charles Kerans, Bureau of Economic Geology, The University of Texas at Austin; Jerry Lucia also aided in preparation of the mosaic photograph of the north wall of McKittrick Canyon. Leslie Melim, Southern Methodist University, provided information on mechanisms of dolomitization in McKittrick Canyon. Keith Rigby confirmed sponge identifications.
Critical reviews that significantly improved the trail guide were provided by Paul Enos, University of Kansas, R. P. Major, H. Seay Nance, and S. C. Ruppel, Bureau of Economic Geology, The University of Texas at Austin, and Jack Babcock, Amoco Production Co. T. F. Hentz was the technical editor, and editing was by Amanda R. Masterson. Word processing was by Susan Lloyd. Illustrations were drafted by Michele Bailey, Joel L. Lardon, Kerza A. Prewitt, Maria Saenz, and Tari Weaver. Margaret L. Evans typeset and created the design.
