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. This bird forages for insects in a range of shrubby habitats, from cedar-studded fields to regenerating woods to mangroves in Florida. Winters in Florida and the Caribbean.
