Special Supplement to Geology of the Grand Canyon: An Annotated Bibliography New Citations Not Included in Vols. 1-4
Published:January 01, 1990
A few publications have been included in this guide and index to Grand Canyon geology that have not been annotated in the Annotated Bibliography of Grand Canyon Geology (Vols. 1-4, Geological Society of America Microform Publicotions 13, 14, 17, 20). To accommodate them, their annotations appear in this section. They will be included formally in the Annotated Bibliography when the next volume is prepared.
Birdse', E, C. H. 1924. Plan and profile of Colorado River from Lees Ferry, Ariz, to Black Canyon, Ariz.-Nev., and Virgin River, Nev. U.S. Geological Survey, 21 sheets, map scale I :36,680, profile scale 1:31,680 (venical scale 1 inch = 20 feet, "subject to adjustment"). (C. H. Birdseye, Chief Topographic Engineer; topography by C. H. Birdseye and R. W. Burchrd; some topography from existing 1903, 1905 Vishnu, Bright Angel, and Shinumo topographic quadrangle maps.)
A compendium of strip maps, lettered A through U, consisting of 14 plans and 7 profiles. Each topographic map is composed is disjointed river segments; 5' intervals of latitude and longitude are marked, existing benchmark positions are noted, Township and Range lines are marked where surveyed, political boundaries are delineated; trails, gage stations, and cable crossings are marked. Topographic contours are 50 feet on land and 5 feet on the river surface. Sheets A-I include the Grand Canyon from Lees Ferry to Grand Wash. Sheets J-L continue the Colorado River to Black Canyon. Sheets O-T are profiles; rapids are marked and tributaries are indicated by name; these profiles are straight-line segments of

Geology of the Grand Canyon
What began as an almost inconsequential mention of "the Big canon" in a geomorphological monograph completed by January, 1856 (Hitchcock, 1857), and followed by just two major publications during the next two decades, now is a publishing record of scores of titles each year. And within the hundreds of papers and monographs that have been produced, especially in the last few decades, there is a tremendous amount of data which can be extracted only by lengthy, sometimes laborious and serendipitous scanning and cross-referencing. About ten years ago, compilation of an annotated bibliography of Grand Canyon geology (including paleontology) was begun. The first volume was published as a Microform Publication of the Geological Society of America (Spamer, 1983). The purpose of this volume, beyond its immediate use as an index to published data, is to consolidate in one volume all the widely dispersed hard data that may be of value to researchers. By quoting the original legends and captions, and by supplementing them with comments or indications of the contents of the figure or table, the user should be able to determine just what items may be of interest to the research project at hand. The author wishes to stress, however, that this first attempt at such a compendium may not satisfy all the needs of various workers.
