Ottawa's snow mountain just keeps piling up

Standing more than 50 metres tall and covering the area of several football fields, the snow storage facility on Clyde Avenue is Ottawa's largest, a towering monument to winter that remains long after the spring melt has finished with the rest of the city.

That's where the CBC's Hallie Cotnam caught up with Bryden Denyes, Ottawa's area manager for core roads, to learn more about the work that goes into stashing all that snow.

"This snow is predominantly from the downtown core area and a little bit south of the facility here," Denyes explained on Ottawa Morning.

The snow is blown into trucks, then dumped here. To get it piled so high, the city contracts special high-velocity snowblowers that launch it to the top of the mound.

Avalanche risk

It can be dangerous work.

"Once we have some warm temperatures there's always a risk of it sliding down, hence the avalanche risk," Denyes said.

Depending on the amount gathered, Denyes said the pile can last well into the summer before it all melts away.

"I've seen the snow here as late as the end of August, so it all depends on the summer we have."

Once that finally happens, the site undergoes a complete cleanup before the snow starts flying again.
