SWEET TREES! So the lava creates a barrier for the trees so the root system has to twist around the areas of rock-so the tree is twisty too. Yeah, I lost the brochure that actually talked about it but, it's something like that.
The stairs down to the ice cave-an old lava tube has a layer of ice on the bottom and is there year round. I can't wait to go again in the summer when it's about 110 degrees outside and there is STILL a layer of ice on the bottom.
