The fourth and last major artifact category is the gray, coil pottery which is most often used to identify archaeological sites as Fremont. This pottery is not very different from that made by other Southwestern groups, nor are its vessel forms and designs distinct. What distinguishes Fremont pottery from other ceramic types is the material from which it is constructed. Variations in temper, the granular rock or sand added to wet clay to insure even drying and to prevent cracking, have been used to identify five major Fremont ceramic types. They include Snake Valley gray in the southwestern part of the Fremont region, Sevier gray in the central area, Great Salt Lake gray in the northwestern area, and Uinta and Emery gray in the northeast and southwestern regions. Sevier, Snake Valley, and Emery gray also occur in painted varieties. A unique and beautiful painted bowl form, Ivie Creek black-on-white, is found along either side of the southern Wasatch Plateau. In addition to these five major types found at Fremont villages, a variety of locally made pottery wares are found on the fringes of the Fremont region in areas occupied by people who seem to have been principally hunters and gatherers rather than farmers.
At the height of this classic Fremont period, about 1,000 years ago, people who in one way or another fit the rather broad description of Fremont could be found from what is now Grand Junction, Colorado, on the east to Ely, Nevada, on the west. They lived as far north as modern Pocatello, Idaho, and on the south to present-day Cedar City, Utah.
