The Gallatin has been awesome. All sections are fishing great. Salmonflies have moved up around Big Sky but fish will still be looking for them in much of the canyon. Otherwise, a Chubby-dropper or double nymph rig will catch em. We like stonefly nymphs, frenchies, or anything with some CDC. Caddis, PMDs, yellow sallies, and salmonflies will dominate the hatches.
