Up to this point, I had followed the Moose River and now was arriving at Lyons Falls, NY. (Location)
At this geographic location, the Moose River enters into the Black River. The volume of flow in both rivers has grown substantially and now, at Lyons Falls, those flows are joined together as the now much larger Black River tumbles over the edge of another precipice.
For those who want to explore the river there is a boat launch area above the weir for those heading upstream and another boat launch area for those wanting to explore downriver from Lyons Falls.
