The Pingo Trail is an 8 mile hike around Thompson Common which takes in the delights of the ice age pools known as pingos. As the ground froze, water underneath froze to create little hills. When the ice melted the earth dropped back down and created the pingos. They are usually found in places such as Greenland and Alaska so it is an interesting and unique place to visit.
