St. Mary's Waterfall just south of the bridge at St Mary's right along Rt 2 south.  Just passed the store on your right after you turn right coming off the bridge, you'll find a pull off on your left.  There is a trail of sorts going up into this small gorge, but there is so much debris in here, it might not be completely obvious.  It can be tricky in spots, and you need to go almost all the way up into it to get a picture of the falls.  This is a cool location, but honestly, you need to wait for some rain if you want any kind of a decent photo, and you will have to get right up on it or else you will be photographing logs and downed trees for the most part.
