Trip Report

Cataract CanyonOctober 2025

A two-person October 2025 run at 6,790 cfs with Lake Powell at 3,544 feet — low-water Cataract in the shoulder season, cold nights, five-day pace. The Big Drops ran technical and bony; the lower canyon exposed sediment shelves that didn't match any guidebook.

Two on the boat, and a white ring on the walls marking where the water used to be.

The far butte holds the light long after the near wall loses it, and the river hands the color back.
