Show WITH SITGREAVES TO THE PACIFIC • • " . •'•' r i " v ' " ^ : Fig. 86. Valley of the Little Colorado River, and San Francisco Mountain. Lithograph based on a drawing by Richard H. Kern. Lorenzo Sitgreaves, Report of an Expedition down the Zuni and Colorado Rivers (Washington, D.C, 1853). tains, valleys, and camping places along the route. Now a veteran mapmaker, Kern would use his field notes to draw the map that would accompany Sit-greaves's final report.41 In addition to his topographical work, Kern also served as the expedition's meteorologist. Daily he recorded the temperature, described weather conditions and clouds, and measured the atmospheric pressure with two aneroid barometers.42 He also made pencil and pen-and-ink sketches of a number of Indian petroglyphs along the Little Colorado. These did not appear as illustrations for Sitgreaves's report, but Kern would later put them to good use 43 Kern continued to collect specimens of flora and fauna, as he had done on the Fremont expedition, but the extent of his collecting is not clear. We do know that upon return home he donated an example of a new species of squirrel, found on San Francisco Mountain, in central Arizona, to the Philadelphia Academy of Natural Sciences.44 163 |
