About this map

The Colorado River carves a winding path across this Central Texas landscape, marking the historic boundaries where Coleman, Brown, McCulloch, and San Saba counties converge. This 1920s survey depicts a rural environment defined by small-scale cattle ranching and early rail transport. The Ft Worth And Rio Grande railroad serves as the primary artery for the settlement of Mercury, while small communities like Winchell and Milburn sit near the river's edge.

Evidence of established community life appears in the scattered local institutions, such as Elm Grove Church and its neighboring Elm Grove School, alongside the Holt School to the south. The terrain is punctuated by distinctive high points like Morgan Mtn and Lost Mtn, while complex drainage systems such as Deep Creek and McDowell Creek feed into the main river channel. Compiled in part from early aerial photography by the U.S. Army Air Corps, the map provides a precise look at the land before modern highway development.
