Wasatch County, Utah: History
The first settlers were Mormon pioneers, in 1859, settling near present Heber City, Midway, and Charleston. On January 17, 1862, the Utah Territory legislature created the county, annexing areas from Great Salt Lake, Green River, Sanpete, Summit, and Utah counties. Heber was selected as the county seat.
Wasatch in Ute means "mountain pass" or "low pass over high range". Heber City was named for Mormon Apostle Heber C. Kimball. The county boundaries were altered in 1880 and 1884, and then on January 4, 1915, the eastern portion was partitioned off to become Duchesne County. The Wasatch County boundaries have remained unchanged since 1915.
