The South Cumberland is not one park, which nobody tells you. It is a scatter of units across the plateau connected by road rather than by trail, and in November the traffic drains out of all of them at once.

What the season gives you is sightlines. The gorges that are green walls in July become readable. You can see the shape of the rock the whole way down, and how the water got where it is, and how long it took.

What it takes away is margin. Daylight is short and it goes fast on a west-facing trail. The sandstone holds water and stays slick for days after rain. Several units have no signal at all, which matters more when there is nobody else on the trail to notice you did not come back.

I sat on a ledge for about forty minutes and did not see anyone. A pair of ravens worked the updraft along the gorge wall, going up without appearing to try, and I thought about how much of what I was looking at was made by water moving slowly over a length of time I cannot hold in my head.

Then it got cold in the sudden way it does when the sun drops below the far rim, and I walked out faster than I had walked in.

That is the whole of it. I am aware it is not much. The pieces I like best are usually not much.
