The river turns gradually westward, passing several national forest campgrounds. Huckleberry Creek joins just below The Dalles Campground. Several miles downriver from there the White River is joined by one of its main tributaries, the West Fork White River, which also originates at a glacier in Mount Rainier National Park, in this case, Winthrop Glacier. A few miles downriver from the West Fork confluence another major tributary joins, the Greenwater River. The small settlement of Greenwater is located at the confluence.
