From David in Yosemite National Park
My father was Chief Park Naturalist in Yosemite for almost 15 years during the '50s and '60's. Ansel Adams was a family friend who helped influence Dad to begin shooting large format black and white photography around the Park.
This particular shot was taken at the height of the Spring snowmelt as can be seen by the state that Yosemite Falls is in...Booming!
