- A giant hides in the forest of Whidbey Island’s Saratoga Woods Park. It has lived there, undisturbed, for thousands of years. The giant is a rock so huge that it could not possibly have been brought there by humans. It is a glacial erratic, dropped on Whidbey Island when the great continental ice sheets of the last ice age melted and retreated. The erratic measures 38 feet high with a circumference of 155 feet, enough to equal a pile of over 100 cars! Waterman Rock was long thought to be the largest erratic in Washington, but was demoted to second place after the Lake Stevens erratic near Everett (34 feet high and 210 feet circumference) was found to be larger. It is hard to appreciate the size of this massive rock from photographs. You will need to visit the park yourself to marvel at this geologic wonder!
