The 1870 US Census includes the military personnel at Camp Crittenden as well as the settlers around the Sonoita Creek Valley. Camp Crittenden was established in 1867 on the mesa overlooking the former Fort Buchanan site. Camp Crittenden was disbanded in 1873 but not before spawning another civilian community: the town of Crittenden. Fifty-three percent of the soldiers and settlers were foreign-born. This census reflects the population in what is now eastern Santa Cruz County.
