Lower Potter Falls is a very nice waterfall that, unfortunately, may be located on private property.  When I visited the falls, I came in from the south side and didn't see any signs indicating that we aren't allowed to visit.  However, on the north side of the creek is a road, a nice lawn area, and stepping stones down to the creek behind a house.  I will attempt to find out if this is actually private property or not, but until then it's probably best to leave this one alone and I would definitely discourage anyone from climbing down to the base.  If the owners of that house happen to see this, I would love to drop by for tea sometime. :)
