Tower Junction to Northeast Entrance Lamar Valley , accessible all year, is winter range for elk and bison. Tower Junction to Canyon Tower Falls , tumbling 132 feet, was named for the adjacent volcanic pinnacles. Tower Creek flows into the Yellowstone River. South from Tower Falls, as you drive up Mount Washington , look east, downslope, into prime grizzly bear country on Antelope Creek. This area is closed to human travel, to offer the bears refuge.
Meadows produce a profusion of wildflowers during the brief summer.
From the Washburn Hot Springs Overlook south of the pass, you can see the Yellowstone caldera. You can see the Teton Range on clear days, on the right beyond the Red Mountains. Because of bear activity here, camping is restricted to hard-sided units only. Exhibits at the Canyon Visitor Center explain the park's geology. Here the Grand Canyon of the Yellowstone River plunges 1,000 feet below you.
