Description

Spectacular Rapid! The highlight of the run.

"Wham" is the Sieve drop directly upstream of the Sentinel Pine Covered Bridge.

"Bam" is the bad hole created by water slamming the Left wall creating bad recirculation into the hole...especially bad at lower flows...deceptively so.

"Thank You Ma'am" is the last beautiful falls dumping into a large calm pool.

All but the most bold of boaters will portage the ugly "Wham" sieve. Portaging on River Right affords a spicy seal launch just above "Bam" while others portage directly behind the River Left sieve via a crack with a sketchy walk on the edge of the sieve. Apparently some boaters regularly fire up the narrow hard to hit sieve line at low water but a screw up seems very likely fatal. The Left portage permits a better entry into "Bam", where as the river right seal launch has you on "Bam" in all of 2 seconds. (Note: Close up Sieve pic in AW Gallery)

Even more conservatively you can climb down directly off the river right seal launching boulder with great care. The down climb is difficult and easy to fall but you will be able to cross a pool, and  climbing over one more boulder. Now you will be downstream of "Bam" and in a calm spot to put in to run the final waterfall.
