Method: daily ERA5 temperatures (Open-Meteo) drive a photoperiod + chilling phenology model; terrain shifts timing ~1 day earlier per 300 m of elevation. Temperature alone can’t tell a maritime autumn from a continental one — two places at the same latitude and the same September can peak weeks apart, because the trees differ — so each region is also calibrated against published peak dates. Estimates, not promises: typically within a few days, occasionally a week or more out. Check locally before you travel.

Miles Canyon
TrailPeak September 2
The Yukon River narrows through a basalt-walled canyon just south of downtown Whitehorse, crossed by the Robert Lowe Suspension Bridge and looped by a trail along both rims. Balsam poplar and aspen at the canyon edge turn gold through September above water that swamped gold-rush boats bound for Dawson in 1898, before police began regulating passage through the rapids below.
