The "Treehouse Boulder" can be found with-in sight of the Highball Boulder. If walking down the hill past "Highball" enter into the open field/meadow and head left towards the "No Opposition" boulder. When halfway through the meadow, turn left again. The boulder is on the right and is obvious due to the giant tree that has fallen on top of it.
"The Slug" begins on the downhill side of the boulder, all the way to the left on a giant jug above the lip. Traverse right along the lip, utilizing some holds on the face before topping out at the highest point.
