This is a tide water creek that flows into Puget Sound near downtown Marysville WA just east of I-5 Marysville 4th Street exit.
Rocks State Park is located in Jarrettsville, MD and there are great natural, dense wooded hiking trails, a wonderful waterfall, and a 190-foot rock outcrop called The King and Queen Seat. The movie 'Tuck Everlasting' was filmed in this park and features all of the aforementioned attributes to the area.
The waterfall (Kilgore Falls) in the Falling Branch section of the park is Maryland's second highest vertical drop waterfall.
