“Generally speaking, the timing of peak fall foliage follows the landscape, with trees at higher elevations showcasing their bright colors first,” ROOST said in a statement announcing the email list. “The most abundant color begins in September throughout the higher elevations, with the lower elevation mountains and valleys in the Adirondack Park reaching peak sometime in mid-October.”

ROOST Communications Manager Jane Hooper noted that pinpointing “peak” color is tricky, given that the Adirondacks are over 6 million acres with a wide array of elevations, temperatures, landscapes, and weather patterns. It’s a moving target and while there is some degree of subjectivity to the foliage observations, they are informed by years of experience from the field.

The information is gathered from a cadre of volunteer leaf observers throughout the Adirondacks, who send pictures and report what they are seeing in their neck of the woods to ROOST, which in turn compiles it into the weekly reports and sends it along to I Love New York, which includes it as part of a statewide map.
