The first (unnamed) people in the region appeared during or after the last ice age on the shores of what remained of Lake Bonneville. Less than five miles (8  km) from Taylorsville evidence of people killing and eating a mammoth have been found. Some of this region's first named visitors were Fremont people who used the area to hunt and gather food along the Jordan River more than a thousand years ago. A large Fremont settlement on City Creek used the land where Taylorsville is located as hunting and foraging especially along the river. In more recent times Ute bands passed through the valley between the marshes of the Great Salt Lake and Utah Valley. Most of the area was dry sagebrush-covered land without any natural water sources except the Jordan River. A well-used Ute trail wound along the west side of the river at approximately 1300 West which the Ute used in spring and fall. Early settlers observed small encampments of Ute in the cottonwoods along the Jordan River. At least one local settler called these people the "Yo-No'". Whether the name is his creation or an approximation of something they said is unknown.
