A bump or two going on at Mt. Shasta recently.

  1. Does Shasta have any history of volcanism, like having been one at some point, or is this just something settling?

  2. Every one of my 80 years we've been told the big one is coming. It's been a big disappointment, especially recently.

  3. One Harry R. Truman having been more than enough, I'd put that thought on the shelf with "careful what you wish for".

  4. Mt. Shasta is an active volcano. It's been a couple of hundred years since it last erupted; there are active fumarols near the summit, as I understand it. It's just impossibly beautiful.

    1. Geologists estimate about every 600 to 700 years. In the late 1700's the Comte de la Perouse was in a boat offshore Northern California and reported seeing an eruption inland that might have been Shasta. Lassen erupted vigorously in 1915.
