I used to get comments on the snorkles on my old Grizzly 660 about "how i was just out looking for the deepest holes" .. In reality i snorkled my bike for the exact situation you went through there. I may not make it through the hole with the bike, but i wont drown in either. Good luck with all the maintenance. Change the diff oils too a few times too!

Snorkel time!!! Hahaha
