River Description

This run is on par for difficulty to the more commonly paddled Three Lynx section.  The rapids are almost all formed from old landslides however, with sieves and boulder hazards existing in places, giving the run a more serious feel.  Most famously so at Killer Fang and The Sieve, both of which can be portaged through large boulders on the bank.

Don't let the hazards keep you from doing the run, between sections of class II are quality class III and IV rapids, in a more remote setting than the other roadside sections of the Clackamas.  Just be sure you are not in over your head when it comes to class III/IV whitewater.  

Read the Killer Fang Section from to orient yourself with where the larger rapids are.

Logistics: The usual approach for this run is from Estacada up Highway 224 which becomes FR 46. Head up along the Clackamas River and at Highway 224 mile 45.7 you will cross the river at Sandstone Bridge which is the takeout. Heading up river you will reach one potential put-in at Riverside Campground located at mile 52.6. Alternatively you can continue up to the Collawash confluence and do the full run by going to mile 53.3 and the junction with FR 63. Turn onto FR 63, cross the river and you will find access on the upstream river left side of the bridge.

Log jam about 200' upriver of Killer Fang. Portage right is your best bet. LOG JAM IS GONE AS OF
