Name. The name of the viticultural area described in this section is “Texas Davis Mountains.”

Approved map. The appropriate maps for determining the boundary of the Texas Davis Mountains viticultural area are two U.S.G.S. metric topographical maps of the 1:100 000 scale, titled:

“Fort Davis, Texas,” 1985.

“Mount Livermore, Texas—Chihuahua,” 1985.

Boundary. The Texas Davis Mountains viticultural area is located in Jeff Davis County, Texas. The boundary is as follows:

The beginning point is the intersection of Texas Highway 17 and Farm Road 1832 on the Fort Davis, Texas, U.S.G.S. map;

From the beginning point, the boundary follows Highway 17 in a southeasterly and then southwesterly direction until it reaches the intersection of Limpia Creek with the unnamed stream which flows through Grapevine Canyon on the Fort Davis, Texas, U.S.G.S. map;

The boundary then proceeds in a straight line in a southwesterly direction until it meets Highway 118 at a gravel pit 13/4 miles southeast of the intersection of Highway 118 and Highway 17;

The boundary then proceeds in a straight line east by southeast until it meets Highway 166 at its junction with Highway 17;

The boundary then follows Highway 166 in a southwesterly direction onto the Mt. Livermore, Texas-Chihuahua, U.S.G.S. map;

The boundary then continues to follow Highway 166 in a westerly direction;

The boundary then continues to follow Highway 166 as it turns in a northerly and then northeasterly direction to the point where it meets Highway 118;

The boundary then follows Highway 118 in a northerly direction until it reaches a point where it intersects with the 1600 meter contour line, just north of Robbers Roost Canyon;

The boundary then proceeds in a straight line due east for about two miles until it reaches the 1600 meter contour line to the west of Friend Mountain;

The boundary then follows the 1600 meter contour line in a northeasterly direction until it reaches the northernmost point of Friend Mountain;

The boundary then diverges from the contour line and proceeds in a straight line east-southeast until it reaches the beginning point of Buckley Canyon, approximately three fifths of a mile;

The boundary then follows Buckley Canyon in an easterly direction to the point where it meets Cherry Canyon;

The boundary then follows Cherry Canyon in a northeasterly direction to the point where it meets Grapevine Canyon on the Mt. Livermore, Texas-Chihuahua, U.S.G.S. map;

The boundary then proceeds in a straight line from the intersection of Cherry and Grapevine Canyons to the peak of Bear Cave Mountain, on the Fort Davis, Texas, U.S.G.S. map;

The boundary then proceeds in a straight line from the peak of Bear Cave Mountain to the point where Farm Road 1832 begins;

The boundary then follows Farm Road 1832 back to its intersection with Texas Highway 17, at the point of beginning.
