Excerpt from Report on the Geology of the Henry Mountains If these pages fail to give a correct account of 'the structure of the Henry Mountains the fault is mine and I have no excuse. In all the earlier exploration of the Rocky Mountain Region, as well as in much of the more recent survey, the geologist has merely accompanied the geographer and has had no voice in the determination of either the route or the rate of travel. When the structure of a mountain was in doubt he was rarely able to visit the points which should resolve the doubt, but was compelled to turn regretfully away. Not so in the survey of the Henry Mountains. Geological exploration had shown that they Were well disposed for exam ination, and that they promised to give the key to a type of structure which was at best obscurely known, and I was sent by Professor Powell to make a study of them, without restriction as to my order or method. I was lim ited only in time, the snow stopping my work two months after it was begun. Two months would be far too short a period in which to survey a thousand square miles in Pennsylvania or Illinois, but among the Colorado Plateaus it proved sufficient. A few comprehensive views from mountain t0ps gave the general distribution of the formations, and the remainder of the time was spent in the examination of the localities which best displayed the peculiar features of the structure. So thorough was the display and so satisfactory the examination, that in preparing my report I have felt less than ever before the desire to revisit the field and prove my conclusions by more extended observation. In the description of the details of the structure a demand arose for a greater number of geographic titles than were readily suggested by nat ural forms or other accidents, and recourse was had to the names of geolo gists. Except that the present members of my own corps are not included, the names chosen are of those whose cognate studies have given me most aid. Mr. Steward and Mr. Howell saw the Henry Mountains before I did. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
