The 2 pm Turnaround Rule

The “2 pm rule” is a turnaround deadline often discussed for Everest: a party that has not reached the summit by a set hour turns back. On Mount Hood the USFS frames the timing around the sun instead, advising climbers to “start very early with a goal of getting up and back down from overhead hazard zones like the Old Chute area before they’re in the sun.”

What a turnaround time does

A turnaround time is a decision made before the climb: the hour at which the party heads down wherever it is, so that enough daylight, energy and margin remain for the descent. It is set in advance so that the decision is not left to a tired party near the top.

Why the sun sets the clock on Mount Hood

The South Side route passes below Crater Rock and up through the Old Chute or the Pearly Gates, below slopes that the USFS treats as overhead hazard zones; icefall and rockfall are on its hazard list. In late summer 2026 the USFS summer statement said “Rockfall will be your primary hazard on the upper mountain this time of year”, and climbing rangers stopped recommending summit attempts for the season. That is why climbs start around midnight to 1 am (The Mountaineers). An afternoon deadline borrowed from Everest does not fit that advice: the USFS goal is to be back below the Old Chute before the sun reaches it.

How long the climb takes

Published estimates run from about 4 to 7 hours up for a fit, trained party; how long to climb has the figures. The safety page lists the other USFS hazards, and the USFS climbing page carries the current conditions reports.
