Which sport was originally called snurfing?

The Snurfer was the predecessor of the snowboard. It was a monoski, ridden like a snowboard, but like a skateboard or surfboard, it had no binding. According to the 1966 patent by inventor Sherman Poppen, it was wider and shorter than a pair of skis, with an anti-skid foot rest. Like a sled, it had a lanyard attached to the front ... Sherman Poppen originally created the device on Christmas Day in 1965, for the amusement of his children. His wife, Nancy, named the invention, noting that the board allowed the rider to surf on snow (thus the name combining snow and surfer).
