TA Ranch Historic District, Historic district in Johnson County, Wyoming, United States

The TA Ranch Historic District is a ranch complex near the North Branch of Crazy Woman Creek south of Buffalo, Wyoming, with the Big Horn Mountains to the west. Its buildings include an 1882 log-and-frame barn expanded in 1904, an 1892 one-story log ranch house with five exterior doors and no internal hallway, a 25-by-35-foot root cellar from 1882, and a 1904 L-shaped cookhouse.

Dr. William Harris of Laramie established the TA Ranch in 1882 after buying Tom Alsop's brand and herd, leaving Charles Ford as manager. In 1892 Wyoming Stockmen's Association hired guns retreated there and fortified it; about fifty were besieged by nearly four hundred locals until U.S. Cavalry from Fort McKinney rescued them on the third day. J.P. Gammon acquired the ranch in 1904 and raised Percheron draft horses, then Hereford cattle and hogs in the 1920s.

The TA brand and herd came from Tom Alsop of Laramie, and Dr. William Harris kept his medical practice there while Charles Ford managed the ranch. From 1904 J.P. Gammon raised Percheron draft horses, switching to Hereford cattle and hogs in the 1920s. The 1915 hog house was split between pens and a room for cutting pork and hides.

The TA Ranch is a working cattle ranch, guest ranch and restaurant south of Buffalo, near the North Branch of Crazy Woman Creek. Visitors are always welcome to view the barn and the property free of charge. Three of the 1892 breastworks remain, on the rise west of the barn.

The barn preserves gunports cut into its upper north and south walls during the 1892 siege, and the ranch house still shows bullet scars. Of at least ten breastworks thrown up by the surrounding locals, three remain, along with the trench the hired guns dug on high ground west of the barn.
