Travelling through the State of Washington provides a family with some of the most incredible opportunities to view and enjoy natural geologic wonders that one will find anywhere in America. The Dry Falls and the coulee itself are remnants of catastrophies of unimaginable size that happened at the end of the last iceage. Try and imagine a water flow passing this point at an estimated rate of 60 cubic kilometers per hour. The cliffs here drop off some 200 feet to the coulee floor below, and this would have been but a ripple in the water surface. An the estimate is that this flow reoccured more than twenty five times spaced relatively evenly at twenty five year intervals. Include this stop as a must as you explore Washington. Start at Grande Coulee to the north and travel south past Banks Lake, accross the Dam at the end turn left to the interprative center and look accross the four mile wide falls. Continue down the coulee, take your time, there are Golf courses, and swimming holes, ancient once inhabitted caves to climb to, and several beautiful lakes that welcome the power boat enthusiast. Stop at Soap Lake to the south, and make sure you take a dip in its healing waters. A motel there on the south end of the lake has quaint and beautiful log cabins, each with its own theme, and two sets of taps, one with lake water one with ordinary supplying water to the tubs. As you travel make sure you give yourself enough time to stop often, and explore the beaches ,restaurants, and antique shops. Do some rock climbing, especially at SteamBoat rock, just south of Grande Coulee. Swim in the beautiful lakes with sandy beaches, concessions, and always clean washrooms and dressing rooms. Take your best cameras and kids and enjoy!!
