A Centennial History, p.15.
The development of hoodoos is an effect
of aeolian action. This picture was taken in 1984 of the Oldman River
Valley near Whoop-Up Drive and above Fort Whoop-Up. It shows the
laundry hill megablock (one of the geological layers) as well as the aforementioned
hoodoos. The wind action is occurring at the end of the coulee rather
than at the base of it, which would nullify the aeolian theory.
