The portion of the gully near Woodmancy Road suffered from a landslide several years ago that destroyed part of the road itself and required extensive repair, which unfortunately disrupts the view of the upper falls. It's also important to note that the mud and clay make-up of the land in this area is very unstable at times of high rainfall. Be careful and check the weather prior to exploring this gully.

Many people are not even aware of the lower reaches of the ravine, that are in a much more natural and beautiful state (compared to the heavily constructed upper falls). The lower gully is surrounded by mature forests which command a beautiful view down into the Tully Valley. There are a few large pools for wading, and since you will be walking downstream, you approach falls from the top and can enjoy beautiful vistas as look downstream into the gorge. 

Once in the ravine, creek walking down some slippery shale will reward you with a much better environment than that closest to the road. There are numerous cascades that you'll have to carefully scale down to reach the top of the main waterfall. About a quarter of a mile from the road, you will reach the crest of the 65 foot Fellows Falls, which you won't be able to see to well. To get a decent view, cross the creek and walk to the right where you will see an opening in the woods and a rough game trail. If you carefully follow the wooded ridge that descends to the right of the gorge, you will be rewarded with brief peeks of the falls through the woods. Continue the descent on the ridge and eventually you will reach an area where you can get to the bottom of the ravine and walk right to the base of the falls. To view the final waterfall, continue downstream a short distance and walk on the hill to the right of the gorge. This will take you to the bottom of the fourth waterfall.

Note: Land to the right of Fellows Falls is posted. Most of the land along the gorge is public watershed land, but also interspersed near the bottom of the ravine is land that was once owned by Allied Chemical, and more recently, Honeywell International. Respect land rights and do not trespass onto posted land.
Markings: posted signs denoting private property.

The area around Onondaga Creek in Tully has always been known for its salt deposits. Native American and early settlers to the region were aware of salt wells at the south end of where Fellows Falls lies. 60 million years ago, the area below Fellows Falls contained shallow sea, which condensed to form salt mineral. This area was historically favored for excellent salt deposits. It wasn’t until 1889 that the Solvay Process Company began mining the salt (1300 feet below the surface). Mining continued until the mid-1980’s. The wells were plugged in the late 1990’s when the DEC became concerned about seepage into streams and ground water.

The area has recently been known for landslides that dropped portions of the clay-based hillsides down into the valley, the biggest being in 1993. This area, as well as the whole Onondaga Creek watershed, are often disturbed by farm run off, gravel mining, and denuding of the hillside for housing developments.
