Less spots than moments:

Top of Beartooth Pass sitting on my bike on the side of US 212 on a night with a full moon looking down at the switchbacks and stars reflecting in alpine lakes on an early August night so cold you could see your breath and so clear you could just see the aurora far off on the northern horizon. I parked there for an hour.

On the hottest day of the year, sitting in the cold air flowing through Devil's Den with a headlight reading "The Shining" and getting the stuffing scared out of me by a fellow "spelunker" right at the scariest part.

Walking a portion of the Ouachita Trail just past Sugar Creek (heading east) that looks like a wood from a Tolkein book. I half expected to see elves or hobbits flitting between the trees or peering over the rocks.
