Henry David Thoreau’s 1862 essay, “Autumnal Tints,” contains colorful descriptions of New England’s fall foliage, including sugar maple and northern red oak, as well as more humble plants like bearded grass and pokeweed. Of special interest to me was Thoreau’s commentary on the red maple (Acer rubrum): he’d noticed that as early as the 25th of September a small red maple on the edge of a meadow had already turned a “far brighter red than the blossoms of any tree in summer” and that the tree was all the “more conspicuous” in contrast with the rest of the forest, which was still green:
Some single trees, wholly bright scarlet, seen against others of their kind still freshly green, or against evergreens, are more memorable than whole groves will be by-and-by. How beautiful, when a whole tree is like one great scarlet fruit full of ripe juices, every leaf, from lowest limb to topmost spire, all aglow, especially if you look toward the sun!
— Henry David Thoreau, Autumnal Tints
In recent weeks I’d spotted solitary maple leaves dotting the trail, splashes of scarlet among the prevailing greens and browns of the forest floor. This Sunday would be the 25th of September — and based on Thoreau’s essay it seemed precisely the right time to go scouting for the season’s first red maples to have fully changed their color. My friend Steve Aaron was looking for a mountain to climb, so I invited him to join me and Odie the Labradoodle for an attempt on Fir Mountain, one of several pathless peaks that rise above the headwaters of the Esopus Creek.
