Spring* is in the air in Alberta! It's gliding season again.
The Alberta Soaring Council's Scout PCK towing Cu Nim's ASK-21B two-seater XCN.
The town of Black Diamond is in the foreground and Turner Valley (home of the Western Canadian oil industry) is beyond the still-frozen Sheep River. The Rocky Mountain Highwood Range is 25 miles away. Black Diamond ground level is about 4000' and the peaks are about 8000'.
Extensive wave activity above 15,000'.

*For those unfamiliar with the Prairies, I should point out that although it's warm enough to spend the day on the gliding field, we won't see any green grass or flowers for two more months!
