Blackfoot RiverTrail Creek Bridge to Cedar Creek (Wolverine Canyon)

These notes cover the access details, route quirks, and source caveats most likely to matter once you get there.

• Official route corridorTrail Creek Bridge to Cedar Creek (Wolverine Canyon); About 10.1 river miles

  American Whitewater Wolverine Canyon reach and access description identifies the endpoint chain, river miles, or managed float corridor.

• Threshold postureNumeric cue retained for planning

  The route remains planning-only; no live go/no-go score is asserted.

• Safety and land managementCurrent manager notices override this record

  American Whitewater rates the reach Class IV-V and describes consistent bony Class IV rapids, a steepest continuous section, poison ivy along the banks, and limited portage options. Treat this as an expert-only canyon with a full rescue and communication plan. The BLM Trail Creek Bridge campground provides the named put-in/take-out, but the downstream Cedar Creek exit is a beach above the rapid followed by a creek crossing and steep use trail to Blackfoot River Road. Confirm current trail condition, road access, and land boundaries before launching. BLM's current Blackfoot River corridor guidance says floating is not recommended below Trail Creek because of Class IV+ rapids. This card is therefore an expert-only exception to that public-float guidance, not a general continuation of the campground float; use the BLM recreation map to confirm the Trail Creek boundary, seasonal road status, and any current closure before committing to the canyon. Use the direct Blackfoot near Shelley gauge as a reach-linked planning input. American Whitewater reports 450 cfs as difficult and warns that conditions get more intense near 1,000 cfs; there is no hard upper-safe cutoff in the source, so on-site scouting and local advice control the go/no-go decision.

• Camping classificationendpoint_campground

  Trail Creek Bridge campground has six semi-developed BLM sites and the put-in. No on-route canyon camping is assumed; Cedar Creek road access is seasonal and the road is subject to Bingham County winter closure rules.

• Overlap decisionRetained as a distinct access-to-access itinerary

  Adjacent cards use different public endpoints and provide a different trip length, hazard set, skill tier, or operating boundary.
