Alfred A Hart 176 - Black Butte (now Cisco Butte) As the glaciers melted after the last Ice Age, many granite boulders like the one in the foreground were left behind. The railroad can be seen descending left to right and crossing a ravine. Above this spot there are twin tracks, but within the snowshed it switches to a single line, and continues this way down to Emigrant Gap, where it becomes two again. Out of sight between the rock and the railroad is the Dutch Flat Donner Lake Wagon Road.
