This is desolate country, and this spot looks like an unlikely place to build a frontier fort. Note the steep slope of the parade ground. This must have been a dismal place for a soldier to be posted, but it was the kind of desert country in which the Apaches thrived. When I took these pictures in 2010 it was hot.
Geronimo surrendered for the last time to troops from Fort Bowie. He, as well as the Apache scouts used to track him down, were sent from the fort to Florida as prisoners. Eventually they were moved to Alabama and then to Oklahoma.
