Overview

A short, technical Class IV–V gorge between Maybell and Deerlodge Park — five miles, narrow runnable window, high consequence.

A short, technical whitewater gorge where the Yampa River cuts through Cross Mountain between Maybell and Deerlodge Park. Roughly five miles of continuous Class IV–V at high water — among the most demanding free-flowing whitewater in Colorado — with named rapids including Snake Pit, Mushroom, and Osterizer. The canyon is rarely run; the window is narrow and the consequence is high.

Gear
Camp Kitchen

On a seven-day trip, you'll cook roughly 20 meals on a folding table in the sand. The constraint isn't ambition — it's ice management. Days one through three, you have real cooler capacity. Days four and five are the transition zone. Days six and seven are pantry cooking.

The best river cooks plan backward from the last night. If your final dinner is still good — not just edible, but genuinely good — the trip ends on a high.
