Welcome to Autumn in Colorado and fall foliage has already begun to show up in some parts of the state - particularly in the high country.
Peak color in the mountains occurs during the last week of September and first week of October -- but also varies by Mountain Zone. In other words, fall color starts to emerge first in the Northern Mountains, then works its way south through the Central Mountains then finally into the Southern Mountains.
Warmer weather typically slows the emergence of color overall. Well-timed bouts of cooler weather helps speed the process along. We don't want bitter cold though.
We'll soon experience an "Indian Summer," and then more consistent snows will hit above treeline. This contrast - between snow and fall colors - will provide for the best photos of the season.
Location Suggestions for Viewing Fall Color:
*Rocky Mountain National Park
*Rabbit Ears Pass
*San Juan Mountains around Telluride
*Lake City Area
