By Tracey Greenway 14 February Interesting Facts About Igloos. We have all heard of igloos, but what do we really know about how they are made?
What is an igloo? What is an igloo made of? How do you make an igloo? To make your igloo, you will need a snow spade and a saw, plus at least another person to help. How long does it take to build an igloo? Having a window is nice on sunny days.
Not all Igloos have windows, but some did. A good window may have a seal skin or Caribou pelt flap on it or others may have a special translucent seal gut to provide light but that will shield the wind. Occasionally a clear block of ice is used as a window. It was not a feature on Igloos; however, the sound of barking dogs will generally announce the arrival of visitors.
After the blocks are positioned, the interior floor area is dug out, so basically the blocks end up haven been laid around a hole that has been dug several feet deep. This gives more height to the interior. Once constructed, and before occupancy a few igloo builders will light a small candle or oil lamp on the interior and let the heat melt a thin layer of the interior snow.
Then the candle is put out and a thin layer of ice forms on the snow blocks inside of the igloo. This provides structural strength to the blocks and is usually strong enough, that a man can stand on top of the igloo without it crushing in. The floor inside is often terraced, with the upper terrace being for sleeping. The reason for this is that cold air is heavier than warm air, so by having the bed elevated, it would be warmer.
No carbon monoxide detectors were required, but some igloos have a small hole cut into the side of the blocks of snow, so as to allow a little air to enter through the hole in the side of the igloo and escape through the top hole. This helps to reduce the carbon monoxide concentration. Tools were often made of various whale bones or from the bones of what they hunted, such as Caribou. In some areas, if they had access to a few trees, then some tools were made of tree branches, etc.
One the more prized possessions one could own were a good set of wooden poles that could be used for supporting summer tents. Also, wood was used to build the dog sleds, another prize possession.
Many people believe incorrectly that Inuit live only in igloos. This myth couldn't be farther from the truth -- Inuit use igloos almost exclusively as hunting camps.
In fact, although most Inuit live in regular old houses now, igloos are still used for the occasional hunting trip. Traditionally, Inuit do not operate in an organized society or government. And, they've never established a widespread tribal identity.
They prefer to live without class divisions. Everyone in a given settlement is equally responsible for finding food and clothing. The family is the central focus of the community, and the senior male serves as the figurehead. Boys are raised to have an almost religious devotion to hunting, and girls have traditionally been taught to seek a talented hunter for a husband.
Today's Inuit primarily support themselves as artists, specifically as jewelers, stone carvers and painters. Inuit culture is very much alive and well. In fact, a study by the Multiculturalism and Human Rights Program at the Department of Canadian Heritage projects that there could be as many as 68, Inuit in Canada by , an increase from 41, in [source: Census of Canada ]. Forget Chalets -- Rent an Igloo Following a long day on the ski slopes, most people like to head back to a toasty lodge, sip on some cocoa and get a good night's sleep under a down comforter.
Others are willing to forego all of those niceties if it means they will get a head start on the slopes the next morning. Igloo villages are an unconventional option for these brave souls. Iglu-Dorf is a chain of igloo villages in five locations across the Swiss Alps. Standard and "romantic" igloos are available for rental during the ski season, from the end of December to the beginning of April.
Some amenities include access to group sauna and Jacuzzi, fondue dinner, nighttime snowshoe walk and subzero sleeping equipment. A few upgrades can get you a private bathroom and sheepskin rugs. In addition to standard overnight stays, Iglu-Dorf also hosts weddings, corporate events and parties. And if you're looking for an icy room that's really luxurious, you can always make a reservation at an ice hotel.
When most people think about igloos, they picture a small, dome-shaped structure built entirely out of blocks of ice. They might imagine a small tunnel leading into the igloo. Actually, this image is surprisingly accurate. We share a pretty similar perception of igloos in large part due to the many television shows and cartoons that have featured them over the years.
The classic s cartoon "Chilly Willy," about a wily and adventurous Alaskan penguin, prominently features his igloo.
