Historical Information

Several surveying expeditions funded by Congress were undertaken by the U.S. Army Corps of Engineers between 1869 and 1879, for the purpose of gathering data upon which to base a detailed topographic map. The expeditions were directed by Lt. George Montague Wheeler, and covered 359,065 square miles, including area within the states of New Mexico, California, Nevada, Arizona, Utah, Colorado, Idaho, Oregon, Wyoming, and Texas. In addition to the detailed topographic surveys, initial astronomic or geodetic points were established in Nebraska, Montana, and Washington Territory. These surveys are informally referred to as the Wheeler Survey.

Numerous mountain peaks and geographical areas in the American West are named after Wheeler, including Wheeler Peak in northeast New Mexico, the highest point in the state; and Wheeler Geological Area, formerly Wheeler National Monument, in Colorado. Wheeler himself made annual field trips to Colorado. His trip in 1874 included areas of northern New Mexico but only reaching as far south as Tierra Amarilla.


Scope and Content

This collection contains data for all of the states within the survey area, with the exception of Idaho and Montana. There are 53 items in the collection, all of them bound volumes of survey observations. Included are books on triangulation, sextant astronomical observations, meteorological records, odometer readings, geodetic data, and observations for time. The bulk of data in the collection pertains to New Mexico and Colorado. Some observation books are undated.
