People in Saskatchewan had to endure some severe weather the last two days, with tornadoes spotted near Moose Jaw, power outages across the province and a family's camper flipped over with six people inside near Regina.

When the storm died down, though, the province was treated to a rare atmospheric phenomenon: mammatus clouds.

The shape of the clouds in this formation are variously describes as cotton balls, puffs, bubbles and, as the name suggests, breasts.
