, in which the U.S. Army had suffered from serious
logistical difficulties. Macomb sought to find a route for military supplies from Santa Fe to central Utah, and also to map the unexplored regions along the route. Though originally political and military in nature, the expedition became "a quintessential scientific endeavor".
Macomb's legacy would include a stone
survey monument that would bear his name and eventually become a part of some geographical intrigue and a few border disputes between New Mexico and both Colorado and Texas, eventually being replaced by the
Preston Monument in 1900. The tri-point for the present states of Oklahoma, Colorado, and New Mexico is supposed to be the intersection between the
