What this forecast looks for

Plain-language explanation from the rule

This forecast predicts when the continental divide peaks will catch alpenglow—that magical pink and orange light that makes the Rockies one of the world's premier golden hour destinations. We track clear sky conditions, sun angle, and atmospheric clarity to identify perfect alpenglow windows.

The Canadian Rockies run along the continental divide, with massive peaks rising directly from valley floors. This dramatic topography means the first and last light hits mountains while valleys remain in shadow, creating spectacular contrasts. The high latitude also means golden hour lasts longer than in equatorial regions.

What makes Rockies golden hour exceptional:

  • Continental divide peaks - Massive mountains catch first and last light while valleys remain cool-toned
  • Vermillion Lakes - Classic location where Mount Rundle catches alpenglow with wetland reflections in foreground
  • Castle Mountain - Distinctive layered peak that glows dramatically at sunset
  • Extended duration - Northern latitude means golden hour light lasts 30-60 minutes longer than southern locations

Best photography occurs at classic locations like Vermillion Lakes for sunrise on Mount Rundle, or Two Jack Lake for sunset on Mount Rundle from the east. Summer solstice brings challenges with very early sunrise times (5am), while autumn offers more reasonable timing with fall colors as bonus.
