Deer Park Sink is hidden by a subdivision and a cluster of oak trees, mesquite branches, and cedar brakes. Part of this sinkhole is enclosed by a fence. One would never expect that there would be a sink behind this fence and subdivision. Deer Park Sink is notable for having a small crawlspace on the inside and narrow size on both sides.

Here is the history of Deer Park Sink.

Deer Park Sink was named after Deer Lane which once served as Davis Lane prior to road re-alignment in 2007. Deer Park Sink also named after the Goat Cave Karst Preserve which is also a park owned by the City of Austin. That is how this sinkhole had received the name “Deer Park Sink”.

Claire Brooks Chastain, Samuel D. Hanson, and Jeanette Dawson Caroll once owned Deer Park Sink. Claire Brooks Chastain owned 39.89 acres of land in South Austin. This land included Deer Park Sink  and Deer Park Cave. Now Deer Park Sink was located on ranch land that was originally part of the Jennings Ranch and had been for many years prior to the 21st century.

For many years Claire Brooks Chastain and Jeanette Dawson Caroll owned many acres of land that once belonged to the Jennings Ranch. Jeanette Dawson Caroll owned the part of the land where one side of Deer Park Sink is located. The part of the land Jeanette Dawson Caroll owned was the southern part of the land where Deer Park Sink and Blowing Sink are located. Claire Brooks Chastain owned the northern part of where Deer Park Sink is located.

Claire Brooks Chastain sold the land to Samuel D. Hanson on March 1, 1995 for a price of $300,000 dollars on a warranty deed with vendor’s lien. (Ref: Travis County Deeds, Instrument #00005262344)

Samuel D. Hanson would own the land before deeding the land back to Claire Brooks Chastain in 1996. Samuel D. Hanson would also deed 2 acres of land to Davis Land, Ltd in 1996. However he would not own the land for very long. Deer Park Sink would go through a handful owners after 1996.

Claire Brooks Chastain sold the land to Davis Land, Ltd. on the date of March 2, 1997 for a price of $300,000 dollars on an extension of real estate. The 39.89 acres of land of Jennings Ranch in South Austin was later owned by Davis Land, Ltd. in 1997. Deer Park Sink was sold to Davis Land, Ltd. on the date of March 2, 1997.

A preliminary plan for the planned subdivision called Deer Haven was laid out and designed by Urban Design Group out of Phoenix, Arizona in 2001. This preliminary plan was a plat map and final plan for the Deer Haven subdivision. Land where Deer Park Cave and Deer Park Sink are located was set aside as a water quality and drainage easement by Urban Design Group and Deer Haven. That is why much of the land that surrounds Deer Park Cave and Deer Park Sink is undeveloped. So they were certainly aware of this cave’s existence and the sinkhole.
