One of the best places in the country to find cool and unusual sights is Nahanni National Park. Located in the Dehcho region of the Northwest Territories, the park is one of the first 12 World Heritage sites to be declared by UNESCO. It houses three of Canada's distinct ecozones that give rise to a wide range of geomorphological structures, including waterfalls, hot springs, canyons and tufa mounds.
Tufa mounds in particular are a special formation of rock pools made from mineral deposits. In Nahanni National Park, they are referred to as the Rabbitkettle hot springs, as they sit over geologically active areas where the water is heated from underground. Water that seeps up from the springs are oversaturated with minerals that eventually - that is, over thousands of years - precipitate into the pool walls.
The largest of the tufa mounds in Canada are 27 metres high and 74 metres wide. The characteristic stacking formations are rather fragile, so the entire area is protected as a Zone 1 Special Preservation Area. Those looking to see the rock pools with their own eyes must be accompanied by Parks Canada Staff as a precaution.
Don't skip out on the Northwest Territories - aside from tufa mounds, there are so many other cool things to see there!
