Oregon Forestsnail "Allogona townsendiana"
Oregon Forestsnail "Allogona townsendiana" The Internet isn't much help on this one but I think that is what it is. It is probably 1.5 to 2" in diameter and they are said to live in areas that have big leaf maples and they eat stinging nettles. Apparently they aren't very common but of course I live in Oregon and I have big leaf maples and stinging nettles.
