Yea, Bob, it just wouldn't have been the same to pose nude when Mt. St. Helens erupted.

My experience with Mt. St. Helens was a big dark cloud of sand raining on us. We didn't know what it was at first, and it was pretty scary to experience. And that was about 150 miles away as the crow flies. We went into our house and hoped that the sand didn't get too heavy for our roof. Then we got news reports that it was getting into car engines and grinding them up. The sand/dust was fine glass shards and almost immediately overloaded and got through normal car air filters. It was also somewhat radioactive at first.
Going naked in the ash would not have been a problem, but a real dust mask was needed. You didn't want to breathe that dust. Those silly "covid" masks would not have helped much. The next day, after the dust settled, we watered our lawns, hosed off the sidewalks, and the city began some street washing.
Hawaii and Iceland have volcanoes with slow moving melted rock lava, not the explosive high altitude sand kind. Getting close to hot lava would keep you warm while naked, and there isn't any dust to get in your lungs. It mostly flows slowly so you can easily keep ahead of the lava on foot. I liked the guy who grilled a hot dog on the lava.
