In February, I had my first hike on the Glory Hole Waterfall Trail in the Ozark National Forest. It was a great hike.
On the day of the hike, it had been above freezing for a few days (in Fort Smith, anyway), but I was pleasantly surprised to see there were still quite a few icicle formations at the stream that forms the waterfall. At the waterfall itself, there was the remnants of a large icicle hanging the length of the waterfall.
Although not an official trail, the Glory Hole waterfall is a great hike.
The waterfall is formed at a hole in the ceiling of an overhang cave. During wetter weather, a small stream flows through the hole.
Below are some more photos of my hike as well as the interactive trailmap and elevation profile I made from my gps.
