The two things—snow and mountains—which are needed for a ski area, are the two things that cause avalanches, large mass of snow and ice crushing down the side of a mountain—often called White Death.
It was the threat of the avalanche and its record as a killer of man in the western mountains that created the snow ranger. He first started on avalanche control work in the winter of 1937 at Alta, Utah, in Wasatch National Forest.
This mountain valley was becoming well known to skiers. It. was dangerous. In fact, more than 120 persons had lost their lives in 1936 and another 200 died in 1937 as a result of avalanches before it became a major ski area.
Thus, development of Alta and other major ski resorts in the west was dependent upon controlling the avalanche. The Forest Service set out to do it, and did, with its corps of snow rangers.
It takes many things to make a snow ranger. The snow ranger must be in excellent physical condition. He must be a good skier and a skilled mountain climber. He should have at least a high school education, and the more college courses in geology, physics, and related fields he has, the better.
He studies snow, terrain, wind, and weather. He learns the conditions that produce avalanches. He learns to forecast avalanches and to bring them roaring on down the mountainsides to reduce their killing strength. The snow ranger learns to do this by using artillery, by blasting with TNT, and by the difficult and skillful art of skiing avalanches down.
The snow ranger, dressed in a green parka which has a bright yellow shoulder patch, means safety for people on ski slopes. He pulls the trigger on a 75 mm. Recoilless rifle, skis waist deep in powder testing snow stability, or talks with the ski area's operator as he goes about his work to protect the public from the hazards of deep snow on steep mountain slopes.
The snow rangers are employees of ______.
A.the Forest Service
B.the Resource Bureau
C.the Tourist Board
D.the Sports Bureau

M: Yes, nurse, I think so. I followed the hospital's advice, and I've only brought a few belongings with me.
W: Good, you can see the reasons why we ask you to do that, the cupboard is really very small.
M: Yes. Nurse, can you tell me what the visiting hours are?

M: I see. What other rules are there?
W: Yes. We start pretty early. We wake you at 6 o'clock, and breakfast is at 8 o'clock, lunch is at noon, there is tea at 3:30, and supper is at 6 o'clock.
M: Oh, that's very different from what I have been used to. You'd better tell me the rest of the rules here.
W: Yes. Well, you can see the no smoking sign. We don't allow smoking in the wards, and the same goes for alcohol. However, if you do need to smoke, there are special lounges.
M: Oh, I don't smoke, so it doesn't affect me.
W: Good.
