Sandier than 55% of California appellations and clayier than 45%. Each grey point is one appellation’s topsoil; appellations nest, so this is a distribution of places rather than of land.

Plus 15% rock fragments by volume, which the triangle does not describe — the three fractions are of the fine-earth material only.

(c) Boundary. The Eagle Peak Mendocino County viticultural area is located in Mendocino County, California. The boundary of the Eagle Peak Mendocino County viticultural area is as follows: (1) The beginning point is located on the Laughlin Range map within McGee Canyon at the point where the 1,600-foot contour line intersects with Bakers Creek near the western boundary of section 25, T17N/R13W. From the beginning point, proceed southeasterly (downstream) approximately 0.2 mile along Bakers Creek to the creek's intersection with the 1,400-foot contour line, section 25, T17N/R13W; then (2) Proceed southeasterly in a straight line approximately 1.5 miles, crossing onto the Redwood Valley map, to the southeast corner of section 36, T17N/R13W; then (3) Proceed west-southwesterly in a straight line approximately 0.55 mile, crossing onto the Laughlin Range map, to the intersection of U.S. Highway 101 and an unnamed road locally known as Reeves Canyon Road, section 1, T16N/R13W; then (4) Proceed southeasterly in a straight line approximately 0.9 mile, crossing onto the Redwood Valley map, to the southeast corner of section 1, T16N/R13W; then (5) Proceed south-southwesterly in a straight line approximately 0.65 mile to the intersection of an unnamed, unimproved road and an unnamed intermittent stream located approximately 500 feet south of Seward Creek, section 12, T16N/R13W; then (6) Proceed west-southwesterly in a straight line approximately 0.9 mile, crossing onto the Laughlin Ridge map, to the southwest corner of section 12, T16N/R13W; then (7) Proceed west-southwesterly in a straight line approximately 0.8 mile, crossing onto the Orrs Springs map, to the 1,883-foot elevation point in section 14, T16N/R13W; then (8) Proceed west-southwesterly in a series of three straight lines (totaling approximately 3.15 miles in distance), first to the 1,836-foot elevation point in section 15, T16N/R13W; then to the 1,805-foot elevation point in section 16, T16N/R13W; and then to the 2,251-foot elevation point in section 20, T16W/R13W; then (9) Proceed south-southwesterly in a straight line approximately 0.8 mile to the 2,562-foot elevation point, section 20, T16N/R13W; then (10) Proceed north-northwesterly in a straight line approximately 0.8 mile to the 2,218-foot elevation point, section 19, T16N/R13W; then (11) Proceed northeasterly in a straight line approximately 0.35 mile to the 2,112-foot elevation point in the southeast corner of section 18, T16N/R13W; then (12) Proceed north-northeasterly in a straight line approximately 0.9 mile to the 2,344-foot elevation point, section 17, T16N/R13W; then (13) Proceed northwesterly in a straight line approximately 1.8 miles, crossing onto the Laughlin Range map, to the intersection of the R13W/R14W common boundary line and an unnamed, unimproved road east of Leonard Lake, section 1, T16N/R14W; then (14) Proceed west-northwesterly along the unnamed, unimproved road to the road's intersection with the 2,000 foot contour line between Leonard Lake and Mud Lake, section 1, T16N/R13W; then (15) Proceed north-northwesterly in a straight line approximately 1.6 miles, crossing onto the Greenough Ridge map, to the 2,246-foot elevation point, section 26, T17N/R14W; then (16) Proceed northerly in a straight line approximately 0.9 mile to the 2,214-foot elevation point, section 23, T17N/R14W; then (17) Proceed northeasterly in a straight line approximately 1 mile, crossing onto the Laughlin Range map, to the peak of Impassable Rocks, section 24, T17N/R14W;
