Ski season will soon be here, so here is a guide to "snow" terms for beginner to advanced... ALP- One of a number of places to ski in Europe. Also a shouted request for assistance made by a European skier. An appropriate reply: "What's Zermatter?" AVALANCHE- One of the few actual perils skiers face that needlessly frighten timid individuals away from the sport. See also: BLIZZARD, CONTUSION, FRACTURE, FROSTBITE, HYPOTHERMIA, LIFT COLLAPSE. BINDINGS- Automatic mechanisms that protect skiers from potentially serious injury during a fall by releasing skis from boots, sending the skis skittering across the slope where they trip over two other skiers, and so on and on, eventually causing the entire slope to be protected from serious injury. BONES- Brittle things of which there are 206 in the human body. No need for dismay, however; there are two bones in the middle ear that have never been broken in a ski accident. CROSS-COUNTRY SKIING- Traditional Scandinavian all-terrain snow-travelling technique. It's good exercise. It doesn't require the purchase of costly lift tickets. It has no crowds or lineups. It isn't skiing. See CROSS-COUNTRY SOMETHING-OR-OTHER. CROSS-COUNTRY SOMETHING-OR-OTHER- Touring on skis along trails in scenic wilderness, gliding through snow-hushed woods far from the hubbub of the ski slopes, hearing nothing but the whispery hiss of the skis slipping through the snow and the muffled tinkle of car keys dropping into the puffy powder of a deep, wind-sculped drift. EXERCISES- A few simple warm-ups to make sure you've been protected for the slopes: 1. Tie a cinder block to each foot with old belts, and climb a flight of stairs. 2. Sit on the outside of a second-story window ledge with your skis on and your poles in your lap for 30 minutes. 3. Bind your legs together at the ankles, lie flat on the floor. Then, holding a banana in each hand, get to your feet. GLOVES- Hand coverings designed to be tight enough around the wrist to restrict circulation, but not so close-fitting as to allow any manual dexterity. They should admit moisture from the outside without permitting any dampness within to escape. GRAVITY- One of 5 fundamental forces in nature affecting skiers. The other four are: the strong force which makes bindings jam; the weak force which makes ankles give way on turns; electromagnetism, which produces dead batteries in expensive ski-resort parking lots; and the last one, that when an irresistable force meets an immovable object, an unethical lawyer will immediately appear. PREJUMP- Manuevre in which an expert skier makes a controlled jump just ahead of a bump. Beginners may execute a controlled pre-fall just before losing their balance and, if they wish, can precede it with prescream and a few pregroans and preobscenities. SHIN- That bruised area on the front of the leg running from the point where the ache from the wretched knee ends to that where the searing pain from the strained ankle begins. SKI!- A shout made to alert people that a loose ski is coming down the hill. Another warning skiers should be familiar with is "Avalanche!" which tells everyone that a hill is coming down the hill. SKIER- One who pays an arm and a leg for the chance to break them. SKIS- A pair of long, thin, flexible runners that permit a skier to slide across the snow and into debt. THOR- The Scandinavian God of acheth & painth. TRAVERSE- To ski across a slope at an angle, one of two quick and simple methods of reducing speed. TREE- The other method.
