i believe justin mitchell in lake city has run it, among others....its basically a large falls to a room to a manky exit falls.....it is on private prop so you have to scout carefully and discreetly but it can be done....justin might be lurking? if he is, he's got solid beta
Argenta Falls: The Argenta Falls
thats the house that sits at the top of the falls themselves
there is another monster falls about a mile downstream called "crookes falls" although the RV resort that sits at the base calls it "granite falls"...its runnable too, but again, private property
its too bad, there are literally two monster waterfalls less than ten minutes from Lake City and the access has to naturally suck!
