While looking for pictures or brochures about Caberfae, I ran across this picture of a ski jumper taken at Caberfae in 1949. You can’t see the jump, but the form (1949 vintage) is unmistakably that of a ski jumper, not an (alpine) terrain jumper.
I have no other information about ski jumping at Caberfae, but the area dates to 1938 for alpine skiing with the first tow installed in 1940. It was not unusual for ski areas to include alpine, cross-country, and ski jumping well into the 1960’s.
If you have any information about ski jumping at Caberfae, please pass it along via the directions on the About MILSAP page.
