Madison Boulder Natural Area Details

Famed for housing the largest known glacial erratic on the continent, this area is a must-see for any nature lover. This granite boulder is believed to date back over 14,000 years and measures over 20-feet high, over 80-feet in length, and clocks in at a whopping 5,000 tons. Because of its uniqueness and size, the boulder is a designated National Natural Landmark. The boulder and the 17-acre area around it were donated to the state by a local family in the mid-1940s. Besides the small trail that leads the rock, there is not much in terms of outdoor activity. However, it is worth a quick stop to say you have seen one of the largest boulders in the world!
