Utah is nearly bisected north-south by the Wasatch Mountains. Between Ogden and Nephi, Utah, these mountains have undergone extensive folding and faulting and reach a maximum height of 12,000 feet at Mt. Timpanogas. South of Nephi this range branches into three great fingers with narrow valleys between. Flanking the Wasatch, east of Salt Lake City, are the lofty Uintah Mountains. These, unlike other ranges in North America, have an east-west axis forming a barrier between Pueblo-dominated lands to the south and the territory of nomads living in the Wyoming Basin to the north. Little evidence of Pueblo occupation has been observed in southeast Wyoming, though there are a number of passes through which occasional hunting parties from the plateaus to the south may have ventured north into the plains of southern Wyoming. This, of course, could only have occurred in the summer, as the area is free from snow for only three or four months of the year.
