Colonel Edwin V. Sumner established Fort Union several miles north of the junction of the two main branches of the Santa Fe Trail, on a tributary of the Mora river, in July, 1851. He chose the location for several reasons. 1) Sumner deemed Santa Fe as “morally degrading.”
There were a lot of bars and brothels, which provided too many tempting distractions for soldiers. 2) Use soldiers to construct a fort & to farm was less expensive than leasing buildings, contracting to vendors, or purchasing provisions.
3) Problems w/Comanche, Ute, and Jicarilla Apache along the southern route of the Santa Fe Trail jeopardized the primary supply line to the new territory. Troops could patrol & be more readily mobilized from the Plains than from the Sangre de Cristos.

The Jemez volcanic field has been active for the past 15 million years. It formed at the intersection of the Rio Grande rift and the Jemez lineament, an ancient northeast-trending fault line that has been a locus of volcanism for the last 10 million years.
The Valles Caldera is the 3rd largest super volcano in the U.S. It sits on top of an older caldera, the Toledo caldera, which may be on top of an older caldera. The calderas were formed during voluminous eruptions in the Jemez volcanic field 1.61 - 1.25 million years ago.
