Rainy fall days are actually some of the best days for both fall color photography and waterfalls. Every time I've checked this spot, the waterfall has barely been at a trickle. But a heavy rain and continual light rain for most of 12 hours changed that for me.
Loved the fall leaves, movement in the pool of water, and the little bit of obvious mountain laurel leaves also framing the falls still.
