Mount Tallac is a mountain peak southwest of Lake Tahoe, in El Dorado County, California.

A "cross of snow" is clearly visible on the mountain's face during the winter, spring, and early summer months.

[10] An estimated 10,000 climb the peak each year via routes approaching the summit from Desolation Wilderness to the west, Fallen Leaf Lake to the East, and access roads from the north.

As fronts approach, they are forced upward by the peaks (orographic lift), causing them to drop their moisture in the form of rain or snowfall onto the range.

The opening sequence of the TV series Bonanza was filmed at the McFaul Creek Meadow, with Mount Tallac in the background.
