I believe it is somewhere just South of Angola, Tunica rings a bell for some reason. The creek on the trail is the ONLY creek with 16 waterfalls throughout the trail and throughout the area as well. The highest waterfall during the time I visited it in 2001 was about 18 feet tall. There is an OLD store that was built in 1800's. The store has showcases FULL of lead bullets found and other CW era artifacts found in the area.
I am posting a picture from google earth as the area I think where it might be. As my memory comes to me, I believe it is OFF the road that leads to Angola, then you turn left on a small 2 lane road going west. Then it comes to like a T in the road, the store is kinda on the upper hill on the T on the right and then across the street is where people park to go hiking on the trails. I looked on Google Earth, but I can't seem to find the location, especially the parking area where I know would be cars.
I had trouble putting the pic from Google Earth.
Here are the coordinites, this is somewhere in the general vicinity;
30°55'36.99"N 91°30'51.76"W
Also it was NOT that close to the river.
