San Diego Mountain on the east bank of the Rio Grande, marked the location of the Paraje de San Diego one of the Spanish campsites along the El Camino Real de Tierra Adentro, in the Jornada del Muerto. The paraje was located just north of the mountain and was the last place to obtain water from the Rio Grande, half a league to the west, until the road reached the river again at Paraje de Fray Cristóbal 30 leagues from Paraje de San Diego.Bishop Tamaron’s Visitation to New Mexico, 1760 from newmexicohistory.org accessed January 10, 2017
