    Lower Trent Conservation

At Bleasdell Boulder Conservation Area, you can take a journey through time with a short hike to the 'Bleasdell Boulder', one of the largest known glacial erratics in North America, estimated to be 2.3 billion years old. The Bleasdell Boulder, also known as the Glen Miller Rock, was studied by Reverend William Bleasdell in the 1800s who wrote of the rock in scientific journals and so brought it to the attention of geologists across Canada. The Boulder measures 13.4 metres long, 7.3 metres wide and 6.7 metres high (44’ x 24’ x22’). That’s over two stories tall
