Alfred A Hart 215 Bear Valley and Yuba Canyon, from Emigrant Gap - The biggest change in this view is the trees. Gradually they are moving in along the borders of the valley. Very little evidence of man can be seen. Even Highway 20 is hidden from view. By contrast, if one turned around he would see busy Interstate 80 and the railroad.
