(a) Name. The name of the viticultural area described in this section is ``Texas Davis Mountains.''
(b) 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:
(1) ``Fort Davis, Texas,'' 1985.
(2) ``Mount Livermore, Texas--Chihuahua,'' 1985.
(c) Boundary. The Texas Davis Mountains viticultural area is located in Jeff Davis County, Texas. The boundary is as follows:
(1) The beginning point is the intersection of Texas Highway 17 and Farm Road 1832 on the Fort Davis, Texas, U.S.G.S. map;
(2) 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;
(3) The boundary then proceeds in a straight line in a southwesterly direction until it meets Highway 118 at a gravel pit 1\3/4\ miles southeast of the intersection of Highway 118 and Highway 17;
(4) The boundary then proceeds in a straight line east by southeast until it meets Highway 166 at its junction with Highway 17;
(5) The boundary then follows Highway 166 in a southwesterly direction onto the Mt. Livermore, Texas-Chihuahua, U.S.G.S. map;
(6) The boundary then continues to follow Highway 166 in a westerly direction;
(7) 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;
(8) 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;
(9) 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;
(10) The boundary then follows the 1600 meter contour line in a northeasterly direction until it reaches the northernmost point of Friend Mountain;
(11) 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;
(12) The boundary then follows Buckley Canyon in an easterly direction to the point where it meets Cherry Canyon;
(13) 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;
(14) 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;
(15) The boundary then proceeds in a straight line from the peak of Bear Cave Mountain to the point where Farm Road 1832 begins;
(16) The boundary then follows Farm Road 1832 back to its intersection with Texas Highway 17, at the point of beginning. [T.D. ATF-395, 63 FR 11828, Mar. 11, 1998]
