Distinguishing the 3 class Vs on the Upper A
Ten Mile is hard to identify without knowing the river pretty well. It doesn't have a super obvious horizon line, and is just after another right hand corner. At medium to lower flow in a kayak it can be a class IV+ read and run, but I still really recommend scouting it (river right). It gets harder as it goes down with two distinct halves. Correct me if I'm wrong Mania, but I think this has the hole on it that killed at least 1 person back in 2005 (in the lower half of the rapid).
No-name. Rather obvious horizon line though it comes up quickly. The river gets really narrow (relatively speaking), the rock walls albeit only ~8ft high are steep. Pulling out can be tricky. At medium to higher flows this rapid alone, if I didn't know the run, would be cause for me to go with someone who knows where to get out to scout/portage. The train tracks are about 20-30ft from the river w/ no vegetation in the way, making the portage and/or scout very convenient and simple. Don't swim- still continuous after this rapid.
Broken Bridge- Rather obvious. As soon as you come around a corner to the right and you see the right side of the bridge is broken, it's time to get out and scout. The rapid starts immediately at the bridge. Here's the catch though- the scout is non-obvious on the left side of the river (walk away from the river, hit a trail, follow the trail downstream 100yards, etc.). One can also get out on river right and hike up a small (40ft) hill up to the train tracks to portage. Thus, the better scout is on the left, and the far better portage is more on the right. It can be scouted on the right okay I suppose- I've never scouted it from the right.
Broken Bridge is an easy class IV read and run at low and possibly medium flows- lots of time between features. At high water it becomes a solid class V. Don't swim, as it's rather continuous class IV for the next 2 miles or so after the rapid.
