It creeps through several thousand square miles under porous volcanic rock before emerging from the springs in the cliffs. Some say the Lost River in central Idaho drops into the ground at the base of the Lost River Mountains and comes out here. Up close and personal tours of the springs are available. Both falls can be seen just off the Mesa Falls Scenic Byway, Highway 47. These falls on the Moyie River can be viewed by turning off U.S. Highway 2 a short distance north of Bonners Ferry.
Visitors can walk above the cascades and get a bird's-eye view of the waterfall.
This 14,000-acre National Historic Reserve is named for the skyline of rock pinnacles, many 60 to 70 stories high. Popular area with rock climbers. Air currents have formed ice sculptures in this natural lava tube, creating striking natural phenomena. The cave, three blocks long and 90 feet below the earth's surface, is one of Nature's magic tricks. Guided tours are available.
