which stands for Falling Banks and maybe the unstable cliffs along the river  ,so maybe its a story they made up to scare people away from the river . But others thru the generations claim to have seen some kind of river monster  either described as a large lizard  or turtle some times with 2 heads and a long tail it uses to grab its prey. Or in the case of the Monongy  a half human half fish .

What ever it is it has been supposedly spotted many times over the years the latest being this past summer when people claimed to have seen an alligator looking creature in the mon.
 
Talk to any Riverman and they will tell you beware of snakes on the deck and with good reason there have been many cases of people disapearing around the mon either by accidental drowning suicide or murder and on average 2-3 body's a month are pulled from the 3 rivers around Pittsburgh.

So is there a river monster ? maybe maybe not but when you see a strange mysterious object floating in the river always beware.   

Thousands have passed this little known marker in Armstrong County Pa. which tells a tale of a now long forgotten and lost Indian village

As you drive along PA 66 also known as River road between Leechburg and Parks Twp when you pass the Bowling Alley and drive in theatre on the right hand side is an old grinding wheel

with a well worn plaque on it which tells a trail of travelers to an established Native American Indian village which once sat near where a waste treatment plant now sits

Most Villages lasted only thru the  summer seasons and moved on come winter  so this village was one of the few established villages which stayed year around.
Its inhabitants more than likely moved to one of the reservation areas set up after the great Allegheny uprising which saw native Americans defeated in a battle in near by Kittaning.
My 5th great Uncle Moravian Preacher and Indian Agent for the government  John Heckewelder  knew the area as  well

This township was named from the river which skirts its southern border. Kiskiminetas, says Heckewelder, is corrupted from Gieschgumanito, signifying, make daylight. Its etymology is: Gisch-gu---day; gisch-que---today; gieschapen---it is daybreak; manitoon---to make. It was probably the word of command, given by a warrior to his comrades, at night, to break up camp and resume the journey, or war-path. It is said in McCullough's Narrative, that the Indians called this river Kee-ak-ksheman-nit-toos, signifying cut spirit. Heckewelder's etymology and definition are more satisfactory to the writer.  Credit to pa-roots.com

The more you study native Americans in Western Pa. the more you learn  learn how a mostly peaceful people where forced to fight back when invaded by the white man .  and their history's and traditions trashed and forgotten. All those treaty's my Great uncle set up to have them broken .
