Splitrock is located upon a bluff overlooking Shoal Creek. Built prior local roads, access to the house was made from Shoal Creek. A trail led from the house down to the creek (see picture left) and past the rock formation referred to as the “Split Rock” a huge boulder split into two pieces forming a canyon approximately forty feet deep (see painting and picture below.) The distinctive song of canyon wrens can still be heard along this section of creek. At the base of this distinctive topographic feature is a small yet robust spring (Buda Boulder Spring) that continues to feed a pool of water once referred to as Split Rock Hole. Remnants of the popular swimming hole can be seen from the Janet Fish bridge crossing Shoal Creek. Also located on this part of the creek was Dog Town and the famed Blue Hole, another beloved swimming place along Shoal Creek for several generations of Austinites.
