When you do the initial descent to Keet Seel, about a 1,000 feet relatively steep drop with "stairs" in some parts and a sandy section toward the bottom, you begin to see the confluence, where three rivers from three canyons converge. Take water shoes for the trip, because you will likely cross water many times on your way to the campground or ruins, including the possibility of having to deal with quicksand, a spectacular, unique journey with some challenges. Insure to check out the Navajo National Monument website ahead of your trip.
