Safety
Route safety
Advanced routeThis route has hazards that can create serious consequences if missed or misjudged. Paddle only with appropriate skill, equipment, and current local information.
Safety details
Use a proven Class IV crew with cold-water protection, throw bags, and a plan to portage the larger bedrock slides. The route is short but consequential, with continuous boulder drops and limited recovery between features.
- American Whitewater describes the Slides as popular partly because the major slides are easy to portage, but the final 1.5 miles becomes continuous Class III-IV boulder water. Scout the line and every portage from legal Pack River Road access before launching.
- Use the direct Pack River near Colburn gauge with 500 cfs as the AW lower runnable shoulder and 2,000 cfs as the upper correlation. Current wood, bridge approaches, road conditions, and the downstream Gorgette transition override the numeric cue.
