“The day began as any other storm-chasing day in the Canadian Prairies. My girlfriend and I followed this particular storm from its birth and observed as it formed this gorgeous shelf structure eight hours later, at the end of the day. The photo was taken just southeast of Fillmore, Saskatchewan, along Highway 33.”
