Osceola Brook Valley. We descended Mt. Osceola back the same way we came climbing over East Peak Osceola. We finished the hike back to our cars on the Kancamagus Highway at 8.4 1940 4:00 PM. Back near the bottom and the junction with the Greeley Pond Trail we came across a White Mountain National Forest trail crew of four working on building bog bridges on the lower end of the Mt. Osceola Trail. We met a total of 16 hikers on this hike.
