Carson Pass
Stretching from the Sacramento Valley to Woodfords, the Carson Pass Highway winds its way through the western slope of the Sierra Nevadas, reaches the summit at Carson Pass, and ends up on the eastern slope of the Sierra Nevada. One of the most visually dramatic of the trans-Sierra highways in California, you will witness views of ragged volcanic skylines, cool green meadows, mountain lakes framed by timber-covered slopes, adventure-filled rock valleys, and distant mountain peaks. The route is located in both the El Dorado and Humboldt-Toiyabe National Forests.

Quarried at Three Rivers, Idaho, this rock is about  13" wide by 9" high.
