Lower Screw-Up - aka (Shaw's Folly)

A great tight technical rapid, but features several hazards, which include: 3 tight entrance slots, at least 4 notable undercuts, shallow rocks in fast current, holes and most commonly high pin or head-to-rock contact potential.

The rapid consists of two main drops. The first part is a set of slots known as the 'Doors'. The Doors are numbered from the river right to the left. Door #1, requires a boof with left angle to avoid pining in the first undercut on river right directly below Door #1. Door #2 is the most narrow slot and requires an off angle entry. Door #3 enters at close to a 90-degree angle to the first two. Door #4 is the far left boulder jumble, usually not runnable except at high levels if logs are not present.

Doors #1, #2 and #3 converge for another 4-5 foot double-drop over shallow rocks into a wave/hole to complete for first half of the rapid. There is a nice eddy on river right and a small eddy on river left to catch before entering the lower part of the rapid. The river right eddy is usually the eddy that paddlers portaging the Doors re-enter the creek. Undercut #2, more of a slopped overhang, is located on river right just below this eddy.

The lower drop consists a ledge hole followed by threading through several ill-placed rocks. Several pins have occured in this location. Beware of the large boulder on bottom left, it is extremely undercut. The large boulder on river right is too, but to a much lesser extent.

The portage trail can be accessed on river right.
