River Description

The "Lower" is actually the last 3 miles of the Box run. It is good, continuous class IV and can be a real riot when the water is high. The rapids are all easily scoutable from the road and stopping at will while on the river is possible at most flows. The drops have a big water feel and are enjoyable, though of a completely different character than the runs upstream. The scenery is still fantastic, with the river exiting from a mountain canyon and blending seamlessly into a desert canyon before spilling out onto the plains. There are great camping spots in the area. The shuttle road will rip the guts out of an ordinary vehicle, so make sure your rig is stout and has excellent clearance.


The various reaches of the Clarks Fork Drainage:
Styx and Stones (Class V+/VI),
The Upper (Class IV/V+),
Honeymoon (Class IV/V+),
The Box (Class V+/VI),
Lower (Class IV/V), and
Crandall Creek (Class IV).

Wind River Range Creeks Need Your Support (WY)

Kevin Colburn

The Shoshone National Forest is in the process of revising their Forest Plan.  The Forest covers much of the rugged Wind River Range and portions of the Clarks Fork of the Yellowstone watershed.  As part of that process USFS staff are selecting which rivers they deem to be eligible for Wild and Scenic River designation. AW is asking for your help and involvement over the next week to provide feedback on this evaluation.

AW weighs in on Clarks Fork of the Yellowstone Management

Kevin Colburn

The National Forest Service is currently in the process of implementing a new river management plan for the Wild and Scenic Clarks Fork of the Yellowstone River. The USFS proposes to maintain all exisiting designated roads but take steps to curtail off-road use that is damaging ecological and recreational values of the river corridor. Today, American Whitewater submitted a letter to the USFS in support of their proposed actions.
