I'm not sure that this is the actual name of this little waterfall, but this is the name on the bridge.
There is parking at the west end of the bridge and you will see the lower part of the falls from the cache site, but walk to the middle of the bridge to see the upper part of the falls. This is flowing even in the summer, but is especially pretty in the fall.
You will also see remnants of the old highway and tank barriers here.
The cache is a small Lock & Lock box with small trade items.
