A Civil War home guard post, acting as buffer to protect older settlements from Apaches and bandits. Scattered local men were members of the 29th Brigade, Texas Militia. Picket homes with dirt floors. Diet of prickly pear salad and fruit, Spanish dagger blooms, hominy, turkey, quail and deer meat. Homespun and linsey clothing dyed blue with Brazil root or gold with agarita. Such was local scene the home guard protected. Camp Rio Frio was later Dogtown, then became Tilden. It proved itself in a rugged era.
