Two snow slides on Calmut Peak on the same day killed 73 people and destroyed 155 buildings. The town remains beneath the area’s wide, steep, and open slopes, and remains vulnerable to avalanches.
This famous spa is known for both its medicinal baths and its avalanches. In December 1717, snow fell continuously for ten days. On January 16 and 17, rain fell on already heavily snow-covered mountains. At 10 a.m., a small avalanche killed three people on the outskirts of the town. An unsuccessful rescue mission returned to town around 7 p.m., just as a second powder avalanche came and destroyed the Saint Laurentius Chapel, three of the baths, all the inns, and fifty houses. The slide also killed 52 people. Avalanches hit the town again in 1720 and 1758.
The so-called Galen avalanche killed 88 residents, 400 cattle, and destroyed more than 100 buildings in the village of Obergesteln. In 1852 another snowslide destroyed only the village bakery.

Three people in the Stura Valley of the Piedmont break a record for surviving after being buried for thirty-seven days. Maria Anna Rocha (45), her sister-in-law, her daughter (13), and her son (6) were trapped with the livestock in stables behind their home when 50 feet of snow buried the entire farm. Because the men of the family were not home at the time ane assumed everyone had perished, no rescue attempts were made. Meanwhile, the stable roof caved in under the snow’s weight, trapped the four people further in a space 12 feet long, 8 feet wide, an 5 feet high. All the livestock died except for two goats. The little boy died after twelve days. The women were driven nearly insane by the smell of dead bodies and constantly dripping water. On April 24 the spring thaw helped uncover the top of the shed. The men returned at this time to bury the assumed dead bodies, only to find the women still alive. The young girl did not seem injured, but the sister-in-law could no longer speak and Maria Anna Rochia had gone completely bald.

On January 9, a storm drops several tons of snow onto the slopes of 22,000-foot-high Nevado de Huascarán, the second highest mountain in South America. The next day, the fresh snow begins to melt and flow down beneath the layers of Glacier No. 511. At 6:13 p.m., about three tons of snow on the north summit breaks loose from the melting glacier and falls 3,000 feet into a gorge below. Two minutes later, after traveling one mile, tons more ice and snow wipe out the villages of Pacucco and Yanamachito, killing 800. The remnants of the village are carried down the narrow canyon, a solid wall almost 50 feet high hurtling at speeds over 100 miles an hour. A gale of compressed air pushes ahead of the mass, destroying buildings in Huaraschuco, Uchucoto, Chuquibamba, and Calla before they, too, fall prey to the avalanche. Exploding out of the canyon mouth, about 39 million feet of snow and debris cascade into the river plain and roll over Ranrahirca, burying homes, livestock, buildings, and over 2,700 people. A
slight bend in the canyon diverts the avalanche, saving the city of Yungay.

A 120-mile-per-hour avalanche rushes into this resort town in a wave 500 to 1,000 yards wide. It buries several cars, then smashes into a youth hostel. 40 youths, most of them Belgian, French, and German students on holiday, are killed while eating breakfast. The powdery snow fills the cafeteria from floor to ceiling, and rescuers use dinner plates to dig out victims. The next day, another avalanche 20 miles away at Bourg-Saint-Maurice takes a line of evacuating vehicles.
An avalanche strikes a military camp, killing twenty-nine officers of the Swiss army. Avalanche threats had been apparent for a month, for snow was laden heavily on the side of 10,200-foot-high Blinnehorn Peak, directly over the camp. The avalanche carried the stone officers’ barracks 200 feet from its foundation. Fortunately, the snow missed the main part of camp, where about 500 enlisted men were staying in wooden huts.
Seventy people, mostly young boys, are killed when a 60-foot-high wave of snow and rock hits two dormitories and a nurses’ residence at the Sallanches Tuberculosis Sanatorium. The snow rolled about 1,000 feet, sweeping up trees, rocks, and other debris, striking the hospital shortly after midnight. The house sheltered about 200 children.
At 3:23 p.m., while many of the city’s 20,000 residents were listening to the closing moments of the World Cup soccer game, a huge earthquake shook the northern half of Peru. The city was soon in ruins - walls collapsed, houses crumpled, and the city plaza was split open. The survivors of this worst earthquake in Western Hemisphere history then heard a low rumble overhead. Millions of tons of icy snow break loose from the high slopes of Nevado de Huascarán, tumbling down into lakes and reservoirs. The ice falls then cause lakes to overflow, sending a wave of mud, ice, debris, and rocks 10 miles down the valley at 3 miles per minute. The city and its 20,000 inhabitants, including some small villages, are buried beneath 100 million cubic yards of mud and rubble. Only 92 survive. This would be known as the worst avalanche in history. A Peruvian relief pilot, flying above the destruction, reported in disbelief, “Yungay no longer exists!”

Eleven mountain climbers are swept off the mountain’s face when a wall of ice and rock breaks off the face of a glacier and sweeps downhill. The bodies are buried under nearly 70 feet of ice and debris. The accident is thought to be the worst in the history of American mountaineering. It happened as 29 climbers tried to scale 14,410-foot-high Mt. Rainier, the highest peak in Washington State. They had reached the 11,000-foot mark when the ice fell. The other 18 party members survived without injury. Park rangers say that ice falls on the mountain are even more dangerous than avalanches because they can occur at any time and under any weather conditions.
