Excerpts from pgs 12-13 of A History of Davis County, by Glen M. Leonard, published 1999.

The culturally related Ute and Shoshone peoples established separate territories that overlapped in the Great Salt Lake Valley. This area was shared by the groups but not aggressively claimed or defended—a fact that greatly benefited the Mormons when they later arrived in the valley Escalante reported the presence of the Utes south of this area in 1776, and the mountain men of the 1820s moved and lived among both groups. Bonneville’s map of the Great Salt Lake area accurately placed Shoshone Indians (including the Goshute branch of the Western Shoshone) north and west of the lake and “Eutaw” Indians east and south of the lake.

Davis County was home to Indians from both groups. Intermarriage created a group known to anthropologists as the Cumumba or Weber Utes. The nomadic lifestyle of Numic peoples centered around a hunting and gathering cycle that took them into the valleys for the winters and into the mountains during the summer months. They hunted large and small game—including buffalo, antelope, and jackrabbits—gathered insects, berries, nuts, and seeds, and fashioned clothing and shelter from furs, skins, bark, and textiles. For the first two decades or so, the Latter-day Saint settlers and the Weber Utes interacted as neighbors. The natives sometimes approached settlers for food, and occasionally an Indian would kill  sheep or steal property or crops. Generally however, the new and old residents lived in relative isolation from one another. After the 1860s, resident Native Americans were seen less frequently in Davis County as Native Americans generally had been displaced from white settlement. Burials continued as late as 1861, and an active winter camp existed near the Weber River well into the 1870s.
