Canadian Glacial Erratic
The Bleasdell Boulder was one of the first natural places we visited when I moved to Eastern Ontario and it left a lasting impression on me. I have always wanted to go back and decided to make a point of visiting it over the next four seasons. Back then you had to go through someone's property to find it. It was a little gem in the middle of no where.
Today, thanks to the help of numerous volunteers the Bleasdell Rock has its own parking lot and trail which connects to the Lower Trent Trail (Lower Trent Conservation). The loop trail from the parking lot to the boulder and back again takes about 30 minutes at a casual clip with intermittent stopping to take photos.
The Bleasdell Boulder is located in Glen Miller, Ontario and is often referred as The Glen Miller Rock. It was named after Reverend William Bleasdell who studied the rock and wrote about it in some of his scientific journals.
The Bleasdell Boulder is not just a rock but a "glacial erratic" (see more on this below), one of the largest in North America spanning 44 feet long, 24 feet wide, and 22 feet high. It has been estimated to be 2.3 billion years old. There something incredibly awe-inspiring about that last figure.
The Bleasdell Boulder was privately owned until 2005 when the Lower Trent Conservation took over ownership of the boulder and surrounding area which is home to wildlife and diverse vegetation.

Where Did Boulder Come From?
Based on its composition it has been surmised that it came from the southern edge of the Precambrian (Canadian) Shield.
