The Sevier Desert covers much of Millard County, being the seafloor of ancient Lake Bonneville. Near the center of the county lies Sevier Lake, a mostly dry remnant of Lake Bonneville. Mountains rim the area, some of which harbor beautiful forests, contrasting with the deserts below, especially the Pahvant Mountains, which form the county's eastern boundary. Fillmore and other farming communities lie at the base of the Pahvant Mountains. Delta sits several miles from the banks of the Sevier River in the middle of the basin.

Great Stone Face

The Pahvant valley in Millard County has several ancient lava flows and extinct volcanoes, including the "Black Rock" lava flow. About 17 miles southwest of Delta, near Black Rock's northwest perimeter is a feature named the "Great Stone Face", which protrudes about four stories above the general elevation. For many years locals have claimed that this rock formation, when viewed at the correct angle, appears similar to a profile of Joseph Smith's face. At ground level, within view of the "Great Stone Face", is a large, smooth-faced rock covered in Native American petroglyphs.

Notch Peak

Notch Peak is located about 50 miles to the west of Delta. The skyline appears to have a notch taken out of it when viewed from Delta.

Little Sahara Sand Dunes

Little Sahara Recreation Area is about 25 miles north of Delta. It is a very popular area for ATV riders.
