At the end of a slot canyon in Oregon, US, there's something special awaiting hikers: the Wahclella Falls. Fed by Tanner Creek, a tributary of the Columbia River, these waterfalls were named after a Native American village by members of the Mazama Mountaineering Club. At the end of a foot trail, visitors can see the spectacular two-tiered cascade that crashes down 105 metres into a pool below, which is the perfect place to take a dip and cool off. While you're swimming, don't forget to keep an eye out for the water ouzel—also known as the American dipper—a species of bird that calls the falls home. They can be spotted flying along the side of the stream and occasionally diving into the water.
