For your consideration is this Rare First Edition Hardcover of "Northwestern Wyoming & Yellowstone 1875", by William A. Jones, Captain of Engineers, Government Printing Office,1875. "Report upon the Reconnaissance of Northwestern Wyoming Including Yellowstone National Park Made in the Summer Of 1873 by William A. Jones, Captain of Engineers, U. S. A. With Appendix." documents the Jones Expedition of 1873, a survey expedition completed during the summer of 1873 with the official purpose of finding a wagon route between the Union Pacific Railroad in the southern part of the Wyoming Territory and Yellowstone National Park. Captain William A. Jones led the expedition which included prominent scientists of the era, botanist, Charles Parry and geologist, Theodore Comstock as well chemists, topographers, astronomers, army infantry, eight wagons and 66 mules. The expedition was successful in discovering and documenting many features of western Wyoming including Togwotee Pass. Reflecting his intellectual bent and geological expertise, the report of his expedition of 1873, included not only elaborate topographical maps and a general descriptive journal but also separate sections on physical geography, meteorology, and the new Yellowstone route to Montana. Succeeding where others had failed, Jones found a passage through the high Absaroka Range near the head of Stinkingwater or Shoshone River. Entering the park near the creek that bears his name, he experienced the thrill of discovery where many previous explorers and adventurers had been thwarted by these imposing ridges. Of particular interest, Jones verified the existence of Two-Ocean Water, a place where, as Jim Bridger had for years insisted, water flowed simultaneously to both the Atlantic and the Pacific.
