I cut this downed Red Oak a couple weeks ago. It came down in the "big storm" back in February. As I was cutting about 6' from the stump, water started pouring out of it! Gushing even. The water poured long enough for me to put down the saw, take out my phone and snap a picture. It scared the crap out of me when a spray of water was flying with the chips. Turned out that the bottom of the tree was hollow. It must have been full of rain water.
