History:  In 1853, the U.S. Congress authorized the Corps of Topographic Engineers to undertake a survey of potential rail routes between the Mississippi River and the Pacific Ocean.  This print is an illustration from the report of the survey at the 41st parallel under the leadership of Lt. Edward G. Beckwith, in the region between the Green River Valley and the Sacramento River Valley, conducted in 1854.  Beckwith's survey was a continuation of the survey at the 38th and 39th parallels headed by Captain John Gunnison, which was terminated in October, 1853 after Gunnison, artist Richard Kern and others were killed by Indians along the Sevier River, in what is now Utah.  The precisely detailed landscape drawings of Egloffstein were coordinated with the maps produced.  The specific location from which the five panoramas were drawn is indicated on the relevant map.  ~~~  Although the title of this map only references the 41st parallel survey under Beckwith, the map includes the survey route of the Gunnison party for October and November, 1853.  It is a continuation of the Gunnison route that follows the route set out in Map 4 of the set of maps associated with that survey.
Beckwith's group began their work on April 4, 1854, after wintering in Salt Lake City.  Egloffstein joined the survey at this time, acting as artist and topographer.   Their work concluded in July, 1854 in the Sacramento River Valley.
