Sandier than 86% of California appellations and clayier than 5%. Each grey point is one appellation’s topsoil; appellations nest, so this is a distribution of places rather than of land.
Plus 14% rock fragments by volume, which the triangle does not describe — the three fractions are of the fine-earth material only.

From the beginning point, proceed in a straight line south 0.3 mile to the line's intersection with the northeast corner of the Vasquez Rocks County Park, T5N, R14W; then (2) Proceed southwest through section 26 along the straight lines and 90-degree turns of the county park boundary line to the line's intersection with the southeast corner of section 27, T5N, R14W; then (3) Proceed southwest in a straight line 0.4 mile to the line's intersection with BM 2258, section 34, T5N, R14W; then (4) Proceed west-northwest in a straight line 0.15 mile, crossing over the Agua Dulce Road, to the line's intersection with the 2,400-foot elevation line and an unimproved dirt road, section 34, T5N, R14W; then (5) Proceed generally west along the meandering 2,400-foot elevation line to the line's intersection with the section 34 west boundary line, T5N, R14W; then (6) Proceed north along the section 34 west boundary line 1 mile to the line's intersection with the 2,800-foot elevation line and the section 27 west boundary line; then (7) Proceed along the 2,800-foot elevation line first generally northeast, then northwest around Saddleback Mountain, and then north across a trail and an unimproved dirt road, to the line's intersection with the section 21 south boundary line, T5N, R14W; then (8) Proceed straight east along the section 21 south boundary line 0.25 mile to the southeast corner of section 21, T5N, R14W; then (9) Proceed north along the section 21 south boundary line onto the Sleepy Valley map 0.6 mile to the line's intersection with the 2,800-foot elevation line and the section 22 west boundary line, T5N, R14W; then (10) Proceed along the 2,800-foot elevation line generally northeast around the 3,166-foot and 3,036-foot pinnacles, then continue southwest to the line's intersection with the section 22 north boundary line, T5N, R14W; then (11) Proceed west along the section 22 north boundary line 0.2 mile to the line's intersection with the 2,600-foot elevation line, T5N, R14W; then (12) Proceed generally west-southwest along the 2,600-foot elevation line to the line's intersection with the section 21 west boundary line, T5N, R14W; then (13) Proceed north along the section 21 west boundary line 0.2 mile to the line's intersection with the 2,400-foot elevation line and the section 20 east boundary line, T5N, R14W; then (14) Proceed generally southwest along the 2,400-foot elevation line to the line's intersection with an unimproved dirt road in section 20, T5N, R14W; then (15) Proceed northwest along the unimproved dirt road 0.15 mile to its intersection with the Sierra Highway, a secondary highway, section 20, T5N, R14W; then (16) Proceed southwest along the Sierra Highway 0.15 mile to its intersection with an unnamed stream, section 20, T5N, R14W; then (17) Proceed in a straight line north-northwest approximately 0.3 mile to the line's intersection with the Angeles National Forest boundary line, an unnamed stream running through Rowher Canyon, and the section 17 south boundary line, T5N, R14W; then (18) Proceed straight east, north, and east, making 90-degree turns, along the Angeles National Forest boundary line to the line's intersection with the section 7 southwest corner, T5N, R13W; then (19) Proceed straight north along the Angeles National Forest boundary line and the section 7 west boundary line 0.5 mile to the line's intersection with the 3,400-foot elevation line, T5N, R13W; then (20) Proceed along the 3,400-foot elevation line generally east, north, then west to the line's intersection with the section 6 west boundary line, T5N, R13W; then (21) Proceed north along the section 6 west boundary line 0.4 mile to the line's intersection with the 3,400-foot elevation line, T5N, R13W; then (22) Proceed generally southeast along the 3,400-foot elevation line, crossing over Latteau, Willow Springs, and Hauser Canyons and continuing onto the Ritter Ridge map, to the line's intersection with an unimproved dirt road at Summit, section 16, T5N, R13W;
