West Virginia Has Volcanic Areas—But All Extinct for 300 Million Years

Yes, West Virginia has three identified volcanic regions, but they are deeply ancient and long extinct:

1. Greenbrier Valley Volcanic Area (eastern WV) – ~1,000 sq mi. Lava flows, ash, cinder cones.
2. Saint Marys Volcanic Area (western WV) – ~500 sq mi. Similar features.
3. Teays River Volcanic Field (central WV) – ~2,000 sq mi. Largest.

Geologic Context

These date to the Late Paleozoic (~300–330 Ma)—the assembly of Pangea. Related to the Appalachian orogeny and earlier rifting. No volcanic activity since.

Today

Erosion has reduced them to subtle topographic hints and mineral deposits. No eruption risk. Not monitored by USGS as volcanic hazards.

Bottom line: Geologically interesting, but "volcanoes in WV" ≠ active or recent. They're fossil volcanic landscapes.
