According to the United States Census Bureau, the town has a total area of 1.5 square miles (3.9 km2), all land.

The first recorded settlers were Peter Skene Ogden's large party of trappers that camped on Deep Creek December 27, 1828.

Some of the discharged members of the Mormon Battalion, on their way home from California to Salt Lake City on September 18, 1848, camped on Deep Creek and also in a cave one mile (1.6 km) east called Hollow Rock.

The beginning of Deep Creek is a large spring at Holbrook which runs through the center of the valley and has never varied even in dry years.

Settled at the direction of Brigham Young, the community was named in honor of Lorenzo Snow, an apostle who became President of the Church of Jesus Christ of Latter-day Saints from 1898 to 1901.

Two unknown soldiers are buried in the cemetery as well as William Robbins, the first settler of the valley and a veteran of the American Civil War.
