Saddle Mountain is a section of New Creek Mountain in Mineral County with a distinctive natural notch, or gap, known as the Devil's Saddle. The actual, proper name for this notch is Dolls Gap.

Dolls Gap looks exactly like a giant saddle carved into the top of the mountain ridge. This is a dry gap or wind gap, meaning no stream runs through it today. It was cut by an ancient stream long ago, but the land was later uplifted, leaving the empty notch high above the valley floors.

The gap is easily seen and often photographed from U.S. 50, which passes several miles to the west.
