Or any other time of year.
From the Department of Interior Twitter feeds:

US Dept of Interior @Interior 16h Is there any doubt fall is best enjoyed in America’s great outdoors? Here’s great example from Devils Tower NM. pic.twitter.com/YRo1U8DSMQ
What do you think Richard Dreyfus thinks when he sees that? Stephen Spielberg?
“Devils Tower NM” means “National Monument,” not New Mexico. This volcano remnant stands in Wyoming.
Old friend, painter and photographer Nancy Christensen Littlefield offers a more close-up view.
And looking even closer, you spy Richard Dreyfus never-wanna-bes:

Climbers on Devils Tower. Photographer Nancy Littlefield said: “There were Native American prayer bundles along the trail around the base. It really is awe inspiring. Early morning gives you the best light to photograph it by.”
Devils Tower is the plug of an old volcano. What’s left is the magma that hardened, and what we see is left after the softer cone eroded away.

- Official site for Devils Tower National Monument
- This was the very first National Monument, proclaimed under the Antiquities Act, by President Theodore Roosevelt, in 1906. Had he visited the site, perhaps in his South Dakota cowboy days? The official notice left off the apostrophe in “Devil’s,” and that typo, “clerical error,” has never been corrected.
