Temperature Changes Change Leaf Color
Autumn foliage tours begin in America in September and last as late as November. New England and Colorado become cooler before the remainder of the country that offers special Autumn Leaves Tours, so they are first to enjoy the increased tourist trade.
As summer temperatures begin to drop, chlorophyll production that keeps leaves green, also drops. Other chemicals are present in the deciduous trees' leaf systems and without the masking chlorophyll, these chemicals reveal other colors in the leaves - a continuum of yellows to deep reds. If evergreens and firs begin to change colors, it is a signal of some sort of problem. One notable exception is the most famous Golden Spruce of the Pacific Northwest.
Other weather conditions can result in early leaf color changes among deciduous trees. One particular summer in Ohio in the late 1980s was cooler than average over the entire course of the season and our leaves in Central Ohio were in full fall colors during the third week of August! People stood around, looking at them.
Drivers pulled off the roads to see them. The change in timing of the colors brought out crowds of appreciative onlookers. In October, some kids dressed as trees with autumn leaves for their Halloween and Harvest parties.
United States National Forests
America maintains many more National Forests than is realized by our citizenry and guests. These large forest are some of the best places to begin a tour of fall foliage. Some of these national forests are within national parks, scenic highways, and adjacent destinations, with few suggestions for enjoying these places in th autumn listed below.
New England Foliage Tours
- The Acadian Mountain Trail - Acadia National Park, Maine
Walk the 1/3-mile loop trail (part of which is accessible) atop Cadillac Mountain. A longer, 20-mile trail is drivable and features th nearby ocean, mountains, and forests of Acadia.
- Mount Washington Cog Railway - Climb to the Top of Mount Washington on the world's first mountain-cl
New Hampshire's Mount Washington Cog Railway - Climb to the Top of Mount Washington on the world's first mountain-climbing Cog Railway train. A 3-hour round trip.
- Finger Lakes National Forest
Just west of New England in New York. The Iroquois Indian Confederacy, later known as the "Six Nations," originated in the Finger Lakes Region. These native Americans were probably the first to use the area now in National Forest.
Train Trips Through the Leaves of Autumn Country
Twenty or forty years ago, travelers could book an overnight train through the Northeast United States and enjoy a day or two of autumn colors. Today, with higher speeds and fewer trains running, we no longer have those "overnighters."
The Mount Washington train listed above is your best choice for a train trip through trees whose leaves are changing. One Southern Ohio train runs a very short line through autumn colors and doubles as a Christmas Express (rides are only about 30 minutes long on either).

The region is beautiful, populated with streams, bluffs, and gorges. A 500-year-old tulip tree is a big tourist attraction, along with many forms of wildlife. Walking and riding trails are numerous and archeological areas are interesting.

Autumn Leaves in California
California residents feared the closing of many of their state parks, because of fiscal problems experienced by the state government. However, many of these places have remained opened, with a few changes. Some staff have been laid off and in some of the more remote parks, visitors must take in their own trash bags and toilet paper, making sure to remove their own trash as they leave.
Many of these parks contain deciduous trees and are still good for Autumn Leaf Watching. A few suggestions are listed below.
- Annadel State Park in Sonoma County - The park hosts big leaf maples and black oaks, 60 miles north of San Francisco. Good for hiking.
- Clear Lake State Park - Black oaks are fund at a large freshwater lake (largest in the state). Indian Nature Trail provides a self-guided tour about the Pomo people of California.
- Henry W. Coe State Park: The Unofficial Website - Enjoys these photos, information blurbs, and free online maps of the park.
- McArthur-Burney Falls Memorial State Park | EveryTrail - Far Northern California - Here we find a number of oaks, redbud trees, California black oaks, Oregon white oaks, white alders, Pacific dogwoods, Oregon ash trees, vine maples, buck brushes, deer brushes, red flowering currants, and more for fall colors.
