both skis are doing the same thing—going in the same direction.
Do not start a descent without first fixing yourankle straps so that there is a reliable emergency connection between you and the ski should you fall and thebinding release. A runaway ski may strand you disastrously.
One of the most useful ski-mountaineering turnsis the short-radius, lifted stem-christiania with the aidof the inside pole. It is accomplished at low speed, andthe combined thrust of the inside ski and the inside polewill serve to drive the outside ski through any but theheaviest snow.
Keep skis together. Consider the photographers inyour party and don't leave a "railroad" track. A narrowtrack, besides looking better, indicates safer skiing. Balance, if upset, can be restored with the shoulders andample bending of knees and ankles; if worst comes toworst and a bump throws you, at least the bump willhave affected both skis equally. Most damage is wroughtwhen a fall, in and of itself, stops only one ski.
