Although Fremont ceramic design styles have the potential to tell archaeologists a great deal about Fremont social interaction and boundaries, they have never been studied in detail. In the Fremont world, painted designs appear almost exclusively on the inside of bowls produced in two different regions of Utah. The firstis the Snake Valley production zone in southwestern Utah where Snake Valley Black-on-gray was produced; the second is the Emery production zone in central Utah where white-slipped Ivie Creek Black-on-white bowls were produced. The similarities in designs on the two main types of Fremont painted bowls indicates regional interaction and exchange of both materials and ideas between the two production zones, while the differences suggest regional distinctions existed within a larger Fremont complex.
