This is a large glacial erratic named "Waterman Rock" which is a boulder deposited in the middle of these woods by glaciers thousands of years ago. Moss covers almost the entire rock and a pathway has been formed around the entire circumference. A few years ago, I was able to climb the rock to have a picnic with some friends.The rock is surrounded by Western Red Cedars and Western Hemlocks. There is a lot of Salal undergrowth, more than any other place I'd ventured to in Saratoga.
