Hydrography Creeks The hilltops of Cougar Mountain form a rough horseshoe-shape around the Klondike Marsh headwaters of Coal Creek, which runs northwest to Lake Washington through Coal Creek Park. Long Marsh Creek, Far Country Creek, Cabbage Creek, and Wilderness Creek are tributaries of May Creek, draining the south side of Cougar Mountain to Lake Washington. Deeply etching the sandstone precipice on the north and east side, Lewis Creek, Kline Creek, AA Creek, West Tibbets Creek, and Claypit Creek carry their water to Lake Sammamish. Marshes Blackwater Pond - In the highlands between Wilderness Peak and Claypit Peak, drains east to Tibbets Creek. Jerry's Duck Pond - A quiet wooded man-made pond near the summit of Claypit Peak. Klondike Marsh - A former reservoir providing water for coal-car steam hoists. Long Marsh - Large swamp between the Wildside Trail and Indian Trail. Shy Bear Marsh - The source of Cabbage Creek in the most remote part of the park. Tibbett's Marsh - The source of West Tibbett's Creek, crossed by a massive downed cedar log. Trog Swamp - Wetland along the Far Country Trail. Lake Boren - Outside of the park, in a separate park in Newcastle. Lake Boren is the largest body of water in the highlands of Cougar Mountain.
