Welcome to The Overlook GeoArt series.
The Overlook Trail System lies within more than 450 acres of open space owned by the Masonic Health System of Massachusetts.
In honor of opening The Overlook Trail System to the public, we have placed 30 puzzle caches which will take geocachers on a wonderful hike on double-track trails through private forest. Please respect MHS's wishes and not use motorized vehicles (ATV, Off-Road vehicles, Quads, Snowmobiles,etc.) Bicycles are permitted, but will add to the challenge as some of the trails are rough.
The container is NOT at the posted coordinates. Simply identify the bird in the picture to get the actual coordinates. Some breeding colonies have been recorded as being located in the same place for hundreds of years. The cliffs containing the colonies appear white when seen from a distance, due to the number of nesting birds present on them.
