About this map

Blowout sits at the heart of this Central Texas landscape, where the boundary between Gillespie and Blanco counties cuts through the hills. This 2016 survey illustrates a terrain defined by complex creek systems and prominent rises, from Tabletop Mtn in the south to Big Mtn in the northeast. The distribution of Comanche Cem and Davis Cem near the upper reaches of Comanche Cr suggests the historical footprint of early ranching families who settled these valleys.

A network of local routes like Comanche Creek Rd and Ranch Rd 1323 connects the various peaks and hollows. Notable landmarks such as Indian Head, Tater Hill, and Coon Mtn dominate the topography, while natural water sources including Sultemeier Springs and Blackjack Spring provided essential resources in this part of the Hill Country. The map provides a detailed view of the drainage patterns for White Oak Cr and Middle Cr, tracing the geographic skeleton of this rural region.
