Background · character · contributors
The Boulder is a pretty little freestone off the Absaroka–Beartooth front, the kind of river you'd happily fish even if it were empty — and it isn't. Rainbows, browns, brook trout, and cutthroat all live here. Once the snowmelt clears off in summer it's classic pocket-water dry-fly fishing, an attractor bouncing through the pockets and a fish meeting it more often than you'd guess.
