August 14, 1863: Amador Road
[Today] we left Volcano and came on up a new road just built, or rather building, across the mountains near the route of the old emigrant road. Soon after leaving Volcano we struck a table mountain of lava and followed it…up a very gentle grade. Deep valleys lay on both sides, and from many points we had wide views of the foothills and the great valley, all bathed in a blue haze of smoke and dust, like our Indian summer intensified, in which all objects faded in the distance and those on the horizon were shut out entirely.
Specimens collected: Campanula prenanthoides.
