The "Wheeler Survey" of the One Hundredth Meridian was one of the four great government surveys of the west. The others were the Hayden, Powell, and King surveys. Wheeler had parties in the field each summer from 1872 to 1878 after which Congress cut off funding for field work but allowed publications to continue until 1884. The results of his surveys were issued as Annual Reports, Progress Reports, and Final Reports with map atlas sheets. For the most part Wheeler surveyed only in the country south of the King Survey. The exceptions were in northeastern California and the Fort Hall area of Idaho. Most of the surveys occurred in central and southern Nevada, southern and eastern California, western Utah, about half of Arizona,western and northern New Mexico, and southern Colorado. The various reports are especially noted for their coverage of the geology, stratigraphy and geography or the regions surveyed. The plates are especially stunning panoramic views of the landscapes.
 The above "progress report contains four plates of views of the Grand Canyon and are the first photographs of the Grand Canyon published in any report. They are by William Bell and are reproduced by photolithography for this report. The photographs include: Rain Sculpture-Salt Creek Canon, Utah; Canon of Kanab Wash - Colorado River Looking South; Grand Canon of the Colorado - Mouth of Kanab Wash, Looking East; and Looking South into the Grand Canon - Colorado River, Sheavwith Crossing. The large folded map shows the regions west of the Mississippi River explored up to 1872. The routes taken by various explorers are shown.
