is there a map that shows the volcanic reach of volcanoes in the united states?

Well... most of them start at Northern California, Mt. Lassen in the Cascades and continue on north through Oregon, Washington, into British Columbia (Canada), then into Alaska. There are very few exceptions (with the really obvious ones of Yellowstone and Hawaii).
The links below take you to some very good maps.Source(s): Geologist http://www.nationalatlas.gov/dynamic/dyn_volcano.h... http://geology.com/most-dangerous-volcanoes.shtml http://vulcan.wr.usgs.gov/Volcanoes/WesternUSA/Map...
