"Map of the United States and Texas Boundary Line and Adjacent Territory determined & surveyed in 1857-8-9-60, by J.H. Clark U.S. Commissioner", U.S. Geological Survey (USGS)

Large and extremely detailed chart by J.H. Clark, U.S. Commissioner, was drawn by J.E. Weyss, circa 1860. The map features the survey lines between Texas and New Mexico with good topographical detail. Information includes forts, Raton Pass, the Santa Fe and Albuquerque trails, numerous explorers' routes, Indian trails, and more. The map is an interesting historical curiosity because it was not published when the survey was finished due to the outbreak of the Civil War. In 1902 it was belatedly included in a Geological Survey Bulletin by Marcus Baker. A very nice example of this large map.

Crisp impression on bright paper. A beautiful example with the faintest hint of fold toning and some tiny fold intersection splits.
