Comment: The past 24 hours of rain have raised water levels a little bit, and the level actually rose a little while we were in creek. Cold day in the rain, but we were already wet anyway! Hopefully the rain keeps the flow a little higher for a few days.

Comment: Flow check, the water was very high and loud with only a few boulders above the water. We hiked in and met another very experienced team on their way out. They said the water is too powerful and there are too many log strainers to run it. We agreed, so we only hiked it and took some pictures. The log jam area was totally flooded with full river flow around both sides of the logjam. With all the rain recently, Duncan is raging!

Comment: Duncan becomes a different animal in high flow. Strong current and swiftwater features appear. Adequate thermal protection essential. Good fun for an experienced team.

Comment: High water conditions and very cold per recent snow. Installed new high water bolt at R2 to eliminate need to use the awkward tree anchor. Crux was the upper pool at R8, a swirling horizontal recirculation that took some effort to escape. Once one person was out, it was easy to assist the rest of the team. (Pool can also be bypassed by rappelling out of the water.) Exited above the big log jam. Duncan is super fun at this level, although teams should be experienced and have plenty of thermal protection.

Comment: Took two sibs on their first-ever canyon here, and it was perfect! Intense enough to push them without terrifying, and the place is just beautiful.

Comment: Low flow but fun day taking friends for their first canyon trip. We exited at the big log jam before the creek crossing and did not do the lower section.

Comment: Fun day out in Duncan on a hot day. A couple anchors had loose hangers that need tightening. Webbing may need replacing soon on a couple anchors, but still in good shape.

Comment: Half-day run of Upper Duncan. Water levels have dropped significantly, but still cold. Tightened a number of loose bolts.

Comment: Water is cold, but currently at fun sporty levels. Teams should be experienced. Ran most of the upper section, jumped out before the big logjam, and went down to descend the Moss Chasm. R5 looked alarming, but isn't deep. Water levels should be dropping off soonishly -- go get it while it's good!
