I think I'm back to being able to post to the list again with a new
address, so I'll respond to a thread from a while back.
If whoever got Marcia's MSH ash wants the recipe for a glaze I
developed using that as the primary ingredient, I'd be happy to share
that. Just contact me privately. And keep in mind that the ash from
each volcano is unique.
Speaking of Mt. St. Helens, I went on a 3-day hike down there last
week, all of it in the Blast Zone. This was on the ridge just across
Spirit Lake from the crater. Incidentally, they just reopened summit
climbs last week, but we didn't do that.
It was really interesting, now that it's been 25 years since the
eruption. There are trees up to about 25' tall. Anything below 5'
high or so was under snow that day, so if it survived being
smothered in ash, it survived. The berry bushes and brush are not
back yet, but the flowers sure are! And the elk love it. We saw
about 110 of them one afternoon.
The ash may be interesting as a ceramic material, but let me tell
you, it makes for a really filthy campsite. But the spot we had was
a 5-volcano view (Rainier, Adams, St. Helens, Hood and Jefferson).
In fact you could see two volcanos from the seat of the outhouse!.
Campsites don't get any better than that!
The lava domes in the crater puff out steam and ash about half the
time. There are now three of them, and they're putting out lava at
about the rate of pickup load per second. But you can't see that
from where we were, 8 miles away. It had built a really huge lava
dome over 24 years, but it belched that out last summer.

If I remember correctly, the towns and cities of Santa Fe, Espanola,
may Los Alamos, and a few others around there, sit in the bowl of one of
the biggest ancient volcanic calderas anywhere. If you have a few maps,
some knowledge of geology, and drive around a bit, you can see the rim
of the thing and it runs for miles. There has got to be a lot of
volcanic ash in that region of the state.

Paul mentions Mt. St. Helens ash in his response to a question. Are there
any other locales in the lower 48 where a person can get volcanic ash from
where it was deposited. I read once that there was a substantial deposit
near Norton, Kansas deposited there millions of years ago by volcanoes in
what is now New Mexico. Anyone know about this?

JB,
There are volcanic ash deposits all over the western US. Lots where I
live on the east side of the Sierra. There is a large deposit just up
the valley from me that I have been using for many years, though not
for specks.
Mount Mazama (Crater Lake, OR) blew ash across northern Nevada about
six thousand years ago. It's many feet thick in places. I would think
there are some various deposits in Colorado too.
good digging,

What about the lava flows up in Idaho? Might be some there?
Best,

There's volcanic ash al over the Midwest from that eruption. As Paul
Herman said there's lots of volcanic ash all over the West. Eastern
Oregon is thick with it from many different eruption cycles of many
different volcanoes. Most of eastern Montana has ash from the
Yellowstone caldera, some of it weathered into clay. That's what
bentonite (named for Fort Benton, Montana) is.
Volcanic ash is not one single thing chemically. It varies according
to what a particular volcano blew out in a particular eruption, and
that depends on what's under that mountain. When you're looking for
specks from your volcanic ash, you need the correct particle size.
It's like air-floated clay- the farther it goes the finer it is. So
in the case of Mt. St, Helens, 10 miles from the volcano, it might be
like gravel, while 200 miles away it's like sand, and 500 miles away
it was like flour.
Last summer I spent 4 days hiking in the blast zone at MSH. Most of
the ground there is like a cinder running track. There were several
places where my hiking buddy could take the aluminum ski pole he
hikes with and shove it two feet into the ground with one hand.
Filthy camping, but very interesting, and you wouldn't believe how
many elk are in there now.

Indeed. The Valle Grande Caldera in the Jemez mountains to the west
of Los Alamos is a 25-mile-across crater that remains from that
historic blow. Up in the Jemez there are huge outcrops of obsidian
too, enough to keep us all in hand axes and knives.
If you've visited the area, you may have been to Bandelier National
Monument, which is the remains of one of the ancient pueblo Indian
settlements. The tufa you see in those canyons is one remnant of the
explosion and it's everywhere in northern New Mexico.
Cheers from a former Los Alamosan,
Linda
