By about 8:30 am, hotspots started showing up in the woods. I think I stated shooting about 7:30 or so. You can see a couple of the in the upper center and right.
From the parking lot, this is maybe twenty steps, a short wade and a scramble down the side of the falls.
Lately, stacked stones are showing up at a number of the streams and little falls I've shot. Is that a thing now? Some are attractive, some, like these, seem a bit awkward. Which is why I choose to shoot around them.
An abstract of the stream bed, looking like mountains running down into the sea.

If you decide to photograph the falls, earlier is better. The sun starts blowing out the background around 8:30 am. Technical details, 18 - 105MM, 100 ISO, circular polarizer, cable release and tripod. I let the camera choose the shutter speed after making sure it was slow enough to smooth the water. You might want to bring kneepads - there's a bit of gravel in the stream bed.
