About this map

Blowout sits at the heart of this central Texas landscape, where the Gillespie Co Blanco Co line divides a terrain defined by high ridges and narrow creek bottoms. The local geography is anchored by prominent elevations such as Pond Mountain, Indian Peak, and the Smith Mountains, while the namesake Blowout Cave suggests the karst nature of the Edwards Plateau. Water sources were clearly vital to the small settlements and ranches of the late 1960s, evidenced by named features like Comanche Spring, Blackjack Spring, and the branching waters of Comanche Creek and White Creek.

Genealogists will find significant local history in the several burial sites mapped here, including Comanche Cem, Davis Cem, and a generic Cemetery north of Long Mountain. These small family and community plots, alongside features like a Radio Tower and a remote Landing Strip, document a rural way of life during an era when early Pipelines began to cut across the historic ranchlands of the Hill Country.
