A glacial erratic the size of a couple of 3 deckers (for those from Worcester, you know what they are) The road goes up near the "rock". Once you walk around it the enormity of this "stone" really hits home. There are no commercial points...More

Huge glacial erratic (larger than a house). It's fun to walk around it (but watch out for the obscene graffiti if you have kids with you...some people have to ruin everything!) Be careful on the road to get there, it's in pretty rough shape.

Definitely worth the detour if you're in the Madison or Conway Area. The Madison Boulder is tucked away off Rte 113. It's only a mile round trip hike and fairly level. While I read about how large the boulder was, it’s truly amazing when you’re...More

One of my favorite things to show visitors to my area. Off route 153 in Madison, between Conway and Silver Lake, is the Madison Boulder. This is a glacial erratic - a GIANT boulder left behind when the glaciers retreated about 10,000 years ago. This...More
