Ok cool. I learn something new everyday. One rock had 8 or 9 on it.
I'll have to take a pic tomorrow but it looks like a tree with no leaves and is bright red in color and I'd like to know what that is as well.
Their is also a fuzzy/hairy critter about half the size of my thumb that opens up and moves around and it looked like it puked one time, blew white creamy stuff all in the water. really weird. I have a lot more to learn about now....
