Roundup to Johnsrud Park

Mile by mile

• 1Roundup RapidIII · RM 29.2 — At the Highway 200 bridge, directly upstream of the Roundup launch — parties putting in at the FAS ramp may start just below it, so decide on the shuttle whether you want it. A big wave train leading to a drop; NRS's Missoula guide warns of a large rock at the base of the main wave train with pin potential (single source — verify locally). Easily scouted from Highway 200.
• 2Thibodeau RapidII-III · RM 17 — About two miles below Whitaker Bridge — watch for the large rock right-center as the river drops (American Whitewater). Big Sky Fishing calls it the Blackfoot's best-known piece of whitewater with the safest route on the right; FWP's float map grades it Class II. Flow-dependent.
• 3The LedgeII · RM 12.8 — A surf wave a quarter mile above Johnsrud that comes in when spring water is up — parking directly above and across the road, popular for park-and-play laps (American Whitewater).
