WVWest Virginia Geography

The lowest ground in West Virginia sits 240 feet above sea level, at Harpers Ferry, where the Shenandoah runs into the Potomac. Most states measure their low point at or near the tide. West Virginia's mean elevation is about 1,500 feet, the highest of any state east of the Mississippi, and not one acre of it falls outside the Appalachian Mountains. No other state can say that.

A shape argued into existence

West Virginia has the most irregular outline in the country, and every kink in it records a dispute. Fifty counties broke away from Virginia during the Civil War and entered the Union as a separate state in 1863, taking their existing boundaries with them, and those boundaries had been drawn for other reasons entirely.

The Northern Panhandle runs about 60 miles up between Ohio and Pennsylvania, pinches to under five miles across in Marshall County, and ends at Chester, which lies farther north than Pittsburgh. The Eastern Panhandle goes the other way, reaching past the Blue Ridge to Harpers Ferry, so Jefferson County is closer to Baltimore than to its own capital in Charleston.

The Pennsylvania boundary is the Mason and Dixon line, surveyed in the 1760s to end a colonial quarrel that predated the state by a century. The western boundary is the Ohio River, but not the middle of it: Virginia's colonial claim ran to the low-water mark on the far bank as it stood in 1792, so the river bed belongs to West Virginia and Ohio's jurisdiction starts at the waterline. The Tug Fork of the Big Sandy makes the Kentucky line, which is why the Hatfields and the McCoys were feuding across a state border rather than a county one.

The Allegheny Front is a weather wall

Running southwest to northeast through Pendleton, Grant and Tucker counties, the Allegheny Front is the escarpment where the Allegheny Plateau breaks off and drops into the Ridge and Valley province. It is also the Eastern Continental Divide. Rain landing west of it reaches the Gulf of Mexico by way of the Ohio and the Mississippi. Rain landing east of it reaches Chesapeake Bay by way of the Potomac.

The escarpment does to moisture what the Cascades do out west. On the plateau side, Snowshoe and Canaan Valley take some of the heaviest snowfall in the eastern states, well past 150 inches in a strong winter. Twenty miles east and two thousand feet down, the South Branch Potomac valley around Petersburg and Moorefield is the driest ground in the state at roughly 30 inches of precipitation a year, dry enough that orchards do well there.

Spruce Knob, Dolly Sods, and a plateau that behaves like Canada

Spruce Knob reaches 4,863 feet on Spruce Mountain in Pendleton County, the top of the Allegheny Mountains and of the state. The red spruce at the summit grow flagged, with branches only on the leeward side because the prevailing wind kills the rest.

Dolly Sods, a short distance north on the same high plateau, is heath and sphagnum bog and wind-scoured rock at around 4,000 feet, a plant community that belongs several hundred miles further north. Logging and the fires that followed it in the early 1900s burned the peat down to bedrock in places, and the ground has been recovering ever since. Canaan Valley nearby is a bowl of roughly 25 square miles at 3,200 feet, the highest valley of its size east of the Rocky Mountains, holding the largest wetland complex in the central Appalachians.

Seneca Rocks rises about 900 feet above the North Fork as a blade of Tuscarora quartzite tipped almost to vertical, a bed of ancient beach sand stood on end by the folding that built the ridges.

The New River runs the wrong way

The New River crosses in from Virginia and flows north, cutting a gorge up to a thousand feet deep straight through the Appalachian Plateau rather than going around it. Rivers do not normally saw across mountains. This one was flowing before the ridges in its path finished rising, which is the basis for its reputation as one of the oldest rivers on the continent. It becomes the Kanawha at Gauley Bridge and reaches the Ohio at Point Pleasant.

The New River Gorge Bridge, opened in 1977, carries US 19 over the gap in a single steel arch 3,030 feet long and 876 feet above the water, turning a 40 minute drive down the canyon and back up into under a minute. Congress redesignated the corridor as New River Gorge National Park and Preserve in December 2020. The Monongahela pulls the same trick in the north, flowing away from the Gulf toward Pittsburgh, where it meets the Allegheny to form the Ohio.

Standing water is scarce. Almost every lake in West Virginia sits behind a dam, Summersville, Sutton, Tygart among them, because the terrain gives water many places to go and very few places to rest.

Cold hollows and hot valleys

The record high of 112 degrees has been reached twice, at Moorefield on August 4, 1930 and at Martinsburg on July 10, 1936. The record low is 37 below zero at Lewisburg on December 30, 1917. Both extremes came from valley floors rather than summits, because cold air drains downhill overnight and pools in the hollows while the ridges above stay warmer.

Flooding is the constant hazard in a state where the only flat ground is beside the water. On February 26, 1972 a coal slurry impoundment failed above Man in Logan County and the wave that went down Buffalo Creek killed 125 people in a few hours. The whole state keeps Eastern Time.
