This is one of a four-cache series along the blue trail on Illinois Mountain in Lloyd, NY. The four caches are:
Illinois Mountain Blue - Bearing (GC5524C)
Illinois Mountain Blue - Range (GC55271)
Illinois Mountain Blue - Base (GC5528Z)
Illinois Mountain Blue - Bonus (GC552A2)
To locate this cache, you must project a waypoint derived from information collected from each of the other three caches in the series. The container is an ammo can not far from the trail.
There are several trail maps of the area available online, one of which is on the Scenic Hudson website. Parking is available at Berian Park. See GC5524C for parking and other waypoints. To reach and circumnavigate the blue trail from the parking waypoint and then return the way you came is a moderate hike of about 4.6 miles, easily accomplished in about 2½ hours. You are of course free to pursue this set of caches in any order you please, but you will find it most efficient to start at the blue trailhead (see GC5524C) and hike the entire trail clockwise, proceeding from Bearing to Range to Base to Bonus. In particular, the trail makes a number of very pronounced switchbacks between GC5528Z (Base) and this cache. Don’t be tempted to abandon it - it’ll take you where you need to go.
This park is owned and managed by Scenic Hudson. Individuals seeking geocaches do so at their own risk and must follow the park rules listed on the park’s kiosk. This cache was placed with the permission of the Scenic Hudson Parks and Trails Coordinator.
