This etymological information from Wikipedia is for Jackrabbitt up there in Valhalla:
The word "slalom" is from the Morgedal/Seljord dialect of Norwegian slalåm: "sla," meaning slightly inclining hillside, and "låm," meaning track after skis. The inventors of modern skiing classified their trails according to their difficulty. Slalåm was a trail used in Telemark by boys and girls not yet able to try themselves on the more challenging runs. Ufsilåm was a trail with one obstacle (ufse) like a jump, a fence, a difficult turn, a gorge, a cliff (often more than 10 metres (33 ft) high) and more. Uvyrdslåm was a trail with several obstacles.
