This is the best section of the Grass! The character of the run is classic Adirondack
"Pool-Big Drop" with sticky holes at high flows. Rainbow Falls, a.k.a. "Large
Marge"5.1+ (Bigger than Magilla) and "Twin Falls" IV+ (Beefed up Fowlersville
Falls w/o the hole) are the "Big Drops" of note. They are spectacular! There are six
other distinctive CL IV-IV+ rapids that are separated by some CL III+ rapids and a few stretches
of flatwater. The area is very scenic so relax and enjoy until you approach the next horizon
line. The run is essentially roadside, but the road is seldom visible. The road is always river

This is the first tree top horizon line you come to. Scout right side then left if you consider running this. It is normally portaged left. Safety is difficult. The hole at the bottom of the falls can be bad at high flows and the wall on the right below the drop is a magnet for flipped paddlers and makes rolling tough.
Lat/longitude coords are approximate, from online maps.
Ledge slide drop with multiple lines and a sticky hole at the bottom.
This 30'(+)ledge slide is a rocket launching pad! Scout right. If you don't see the line think about walking. Hint try and finish between the two Rooster Tails at the bottom right. Getting off-line or flipping can be ugly.
The Iron Bridge crossing the river marks this drop (bridge connects Lake George Rd to Tooley Pd Rd). Watch the hole at the bottom, it can/will eat your lunch, especially at high water. Scout right at Med and low flows, high flows scout left. Portage is easiest left I'm told.
Multiple lines. Left side slide is easier. The center ledges and holes offer a tricky CL V option. Scout the center and right lines from the right. Scout Left line from the left. -
