In 1983 TxDot archaeologists found one of the oldest and most complete prehistoric human skeletons while building RM 1431 connecting Cedar Park with Round Rock and Interstate 35. They named her the Leanderthal lady after nearby Leander (because it rhymed well with Neanderthal) even though the find was nearer to Cedar Park.

Leanderthal Lady Marker

On Dec. 29, 1982, Texas Highway Department archeologists uncovered the skeleton of a pre-historic human female at the Wilson-Leonard Brushy Creek Site (approx. 6 mi. SE). Because of the proximity of the grave site to the town of Leander, the skeleton became known as the Leanderthal Lady. Carbon testing indicates

the woman lived 10-13,000 years ago. She was about 30 years old at the time of death and measured 5' 3" in height. As one of the earliest intact burials uncovered in the United States, the site is a valuable source of information on the nation's prehistoric past.

Location: South Side of RM1431 approximately 1 mile West of Parmer Lane.
