So far, 2013 has presented some amazing outdoor winter weather fun. Sledders, skiers, and snow riders of all sorts have been major region to enjoy our cold playground. If you are in the snow, be in the know. Compacted snow and avalanche safety is paramount for any winter travel straight into or near avalanche geography.
As always, the local snowpack continues to grow and alter. The early season riding conditions in the valley have been the very best in recent memory. Overdue December saw almost 2 hundred cm of snowfall more than an eight day period of time. The air temperatures remained small, and winds calm during that storm yielding particularly light, and fluffy, "blower" powder snow. It was common to see ideal densities as low as 53 Kg/m3, very light-weight for the Elk Valley. In early Economy is shown, strong to extreme form top winds redistributed of which light snow to form massive weak cornices, and wind slabs on lee slopes. Slopes that face northeast so that you can southeast saw the majority of the the wind loading, however there were numerous short periods in which change or opposite loading taken place on slopes that deal with northwest to southwest.
For January 9, a thaw occurred up to 1500m, which brought on widespread natural avalanches, and left out weak, rain soaked compacted snow at below tree set elevations. Following the thaw, a localized melt freeze crust developed in the same area. Current smaller storms have created out of the way storm snow instabilities. These instabilities can easily surprise even experienced mountain travellers. Know the terrain you are in, and know what is ongoing beneath the snow.
The influx hazard has been changing daily. There are now several avalanche complications, and weak layers to worry with.
Avalanche Gear Tip of the Month
When is the past time you did a range weight and dimensions your transceiver? Testing both Research and Send functions, with the signal strength and yardage, is a vital part of pre vacation planning for any travel inside avalanche terrain.
All transceivers available today operate on the same rate of 457kHz. Therefore, all models are compatible. However, match ups, and performance deteriorates over time. Our recommendation is that your avalanche transceiver be replaced by the end of the manufacturer's warranty. The majority of devices on the market today will offer a couple 3 year warranty period, after which it is time to get a new one. Over the life of a transceiver, unforeseen dropping or bumping may well affect the performance of the transceiver's aerial. This damage can quicken frequency drift, a volume slightly less or more than the required 457 kHz. Frequency drift regarding +/ 30 Hz can result in your 50% reduction in the range of the transceiver. This will result in erroneous signals, as well as increased search time.
Seconds and minutes save resides Canada Goose Womens in an emergency avalanche rescue predicament. Age of the device, temperature, frequency drift, and battery life could greatly reduce the range of your transceiver. To get optimal Transceiver performance:
Check and change your batteries often. Under no circumstances leave for home having less then 70% battery power. You'll want to use the correct batteries for ones device, as some more modern models operate only with Lithium batteries, which have different discharge shape than alkaline batteries.
