Photo: Frost flowers on CamBay’s ice

A field of tiny frost flowers grows on the thin ice in Cambridge Bay Oct. 13. For frost flowers to grow, you need a minimum temperature difference of 15 C, between the ice surface and the air. Under bright sun and little wind, temperatures in this western Nunavut town ranged between -12 C and -16 C on Oct. 13. (PHOTO BY JANE GEORGE)
