The guidebook mentions archaeological sites in Sierra Valley, but the instructions are too vague to locate an exact locality. Likewise, stop 22 is supposed to be a stone quarry from which the early natives got stone for toolmaking, but the directions are inaccurate; also, traffic conditions when I drove through were discouraging on both days I tried to find it. I mention these two stops for completeness' sake.
Day 1, Coast Range: 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9
Day 2, Sierra Nevada: 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18
Day 3, Sierra Nevada: 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28
