Unless I am mistaken, the Sierras are tectonic in origin, not volcanic. Not to say we don't have geothermal springs and vents, but I think the volcanos tend to be more solitary at weak points in the plates rather than where they ram together. Shasta and the 4 up north, Bachelor, Hood, St Helens, and ?Rainier?

Don't know about Mammoth. I would have said it was part of te Sierras, not volcanic, but don't know it's history.
