Description

The Upper Ammo needs a lot water for a fluid run. Therefore you would be hard pressed to find this river running unless everything else in the neighborhood is at or near flood stage. The river itself is an easy class I-II at the begining and eventually builds up to a steady class II with a few small ledge drops. Gorge-us is the most difficult section in this run. It is recognized by a sharp right bend up against a shear granite wall on river left approximately 4.8 miles below the put-in. Gorge-us should be considered a class II+ or III depending on level. It is easily portaged on river right. Be aware that most of this run is wild and a difficult bush wack back to civilization, it makes for a great northern New England wilderness experience but a nightmare if problems arise.
