Throckmorton County is a 900 square mile, sparsely populated jurisdiction in north central Texas. The landscape is defined by a transition from the oak-dominated Cross Timbers to the scrubby grasslands of the Plains. The area explored lies about 1 mile from the Brazos River where Hog Creek empties into it, and a few hundred yards away from Coon Hollow, a drainage bounded by exposed bluffs of sandstone, rising 30 feet above the horizon. While these features are not particularly impressive, they do vary from the norm of relatively low, rolling hills of the surrounding terrain. If this area of northeastern Throckmorton County had a name, it would be Koger, a small community that once had a school, but leaves no evidence of establishment today.
