Genesee River rambling in Pennsylvania’s Northern Tier, where the reward is the fiery brook trout

I had come down from southern New York into the northern border area of Pennsylvania, following the Genesee River, but going against the current.
I was now upstream in the land with the strange and little known Triple Divide, a place where the drainage of the area flows in three directions each with a far distant destination – the Gulf of Mexico via the Allegheny River; mid-Atlantic Ocean via the Susquehanna River and the Saint Lawrence River and north Atlantic via the Genesee River and Lake Ontario.
