I guess I wouldn’t know pumice if I saw it. Or maybe I would now! lol
I got stuck between three trees on a slippery mud track in the Cascades of WA once. Two on the passenger side and one on the driver’s side. I really did think I was going to be walking 45 miles out of the mountains to my sister’s house that time.
Without doing too much damage I finally finagled it out of that one. Thankfully there was a hard bottom under the mud puddles.
I can attest to a lot of pumice around the Crater Lake area, FRiend!
