This is a photo of a Virginia Creeper vine on a tree. It looks like Poison Oak but the Oak as 3 leaves like Poison Ivy. This plant will get you if you break its stem and get the juice on your skin but not as bad as with Oak and Ivy. This was taken on the deer trail up of the spillway. The other photo is of a Lyre-leaf Sage plant. They are all over the park and this photo was taken by the trail by the pumping station. It was pretty lavender trumped shaped flowers.
