Cheat

Adam dropping into one of the big holes on the center-right side of Teardrop.
Adam takes a deep breath as he gets ready to sub through the Particle Accelerator in Upper Coliseum- if you aren't on a riverboard, you might want to be a little farther to the right!
Sean gets some air as he pops out of the backwash of Big Nasty- who says November is too late in the season for some riverboarding?
This rapid never seems to show up in descriptions of the canyon, but it is definitely one of the harder rapids; an approach down the right side of the river drops you into a pretty stiff wave/hole feature, the runout of which is a sievy boulder jumble in the middle of the river. In this photo, Sean is subbing through the main hole and Adam is lining up his approach.
Lower Coliseum is a pretty tricky rapid despite being less intimidating than Upper Coliseum; the safest route is to the river right (photo left) of the large triangle rock (Coliseum Rock) in the center-left portion of the photo. Going left of Coliseum Rock leads you into several big holes- a bad place to be, considering that Pete Morgan's Rapid is just downstream.
Sean has just subbed through the large pourover in the center of Teardrop, and is lined up to punch through some more squirrely water in the runout. For those that don't know (or can't tell by the photo), the easiest line through this rapid involves hugging the far river left (photo right) side of the channel, avoiding the nasty pourover in the center of the river and the ledge holes along the outside river right edge of the turn.
Sean is lined up perfectly to punch through the deepest part of the Particle Accelerator, the big hole on the left downstream side of the second drop in Upper Coliseum. Out to Sean's right and slightly behind him in the photo is the Cloud Chamber, a hole you definitely don't want any part of.
This is a good photo of the two drops of Upper Coliseum, taken from the eddy on river left at the base of the second drop. The hole closest to the bottom of the photo is the Particle Accelerator- big but relatively benign at low water, a boat flipping monster at higher water. On the opposite side of the small tongue behind the Particle Accelerator (and slightly upstream) sits the Cloud Chamber, a nasty recirculating pourover which is boxed in by the current going over second drop- looks like a killer to me. In the back of the picture you can see the ramp dropping down into Recyclotron, a huge, recirculating, nearly river-wide ledge hole that only gets bigger and badder as the water rises. The proper line is easy, but is very intimidating and requires some precision- stay to the left of Recyclotron, then cut to the right towards the middle of the river, riding the tongue between the Cloud Chamber and the Particle Accelerator.
