The 520,000-acre Waggoner Ranch is for sale for $725 million — about $1,400/acre. It is said to be the largest contiguous ranch in the U.S., and has been owned by the Waggoner family for more than 100 years.
Ownership of the Waggoner Ranch has been in litigation for more than 20 years. The suit was originally filed in 1991 by Electra Waggoner Biggs, one of the heirs, who died in 2001. Electra was a sculptor; her sculpture of Will Rogers on his horse Soap Suds is on the Texas Tech University campus.
The colorful history of the Waggoner family was documented in an article by Gary Cartwright in Texas Monthly in 2004. It’s a great read.
The ranch has its own website, www,waggonerranch.com. The ranch is located in six counties — Archer, Foard, Knox, Baylor, Wichita and Wilbarger. Here is a map of its boundaries. Of course it has oil, which has held the ranch together, but according to Cartwright the ranch has no groundwater.
