Alberta Soaring Council

the Diamond &
record history of the
Cowley wave

 

compiled by Ursula Wiese - ASC Historian

excerpted from "Stalking the Mountain Wave"

and further current data added post-1996


ASC Home Page | Cowley home page


This data has been compiled from all available written sources and contact with individual pilots. It's possible that USA visitors to Cowley other than McClanahan in 1961 achieved Diamond climbs also, but the SSA does not keep this data.
