Upper Tract, West Virginia
Upper Tract is an unincorporated community located in Pendleton County, West Virginia, United States. The community lies along U.S. Highway 220 at the confluence of Reeds Creek and the South Branch Potomac River. The community took its name from a nearby 18th-century pioneer settlement. Two local structures — the Cunningham-Hevener House and the Pendleton County Poor Farm — are listed on the National Register of Historic Places. Upper Tract is notable as one of the driest places in the United States east of the Mississippi River, owing to an isolated rain shadow from Spruce Knob to  the west. Between 1899 and 1930 Upper Tract averaged only of precipitation, and in the extreme drought year of 1930 it received a remarkably low for the entire year – the lowest annual precipitation ever recorded in the US east of the Mississippi, and indeed less than fell during that year in such dry cities as Tucson and San Diego.
