Avalanche believed to have killed three top climbers in Alberta, Canada.

Three of the world's top professional climbers are believed to have died following an avalanche near Banff in Alberta, Canada, this week. Austrians David Lama, 28, and Hansjoerg Auer, 35, and American Jess Roskelley, 36, failled to check in with Parks Canada at an appointed time during an attempt to climb the notoriously difficult east face of Howse Peak in Banff National Park, sponsored by clothing company North Face. This prompted a fly-over of the area, which found evidence of a large avalanche on the slope, with scattered equipment among the debris. Attempts to get a rescue team to the site on the ground are being hampered by bad weather in the area.

Avalanches are caused by the mechanical failure of snowpacks; essentially when the weight of the snow above a certain point exceeds the carrying capacity of the snow at that point to support its weight. This can happen for two reasons, because more snow falls upslope, causing the weight to rise, or because snow begins to melt downslope, causing the carrying capacity to fall. Avalanches may also be triggered by other events, such as Earthquakes or rockfalls. Contrary to what is often seen in films and on television, avalanches are not usually triggered by loud noises. Because snow forms layers, with each layer typically occurring due to a different snowfall, and having different physical properties, multiple avalanches can occur at the same spot, with the failure of a weaker layer losing to the loss of the snow above it, but other layers below left in place - to potentially fail later.

Howse Peak rises to 3295 m above sealevel, and 1600 m above the surrounding plain, making it the highest mountain in the Waputik Mountains (a subrange of the Rockies) and the 46th highest peak in Alberta.  The mountain has a subarctic climate with temperatures reaching as low as -20°C in winter, when significant snow can accumulate, feeding a glacier on the western flank, as well as the Howse, Mistaya, and Blaeberry rivers. In spring the the area encounters warmer weather, leading to significant melting and frequent avalanches.

I've been to other spell casters without seeing any result.I just wished I came to you earlier,I got the best from you. My ex husband was gone for a year and I went everywhere and other spell casters for help but no result until my friend introduced me to Dr. Miracle. After the Love Spell was done, I finally got a call from him.His spells worked wonders and my husband is back with full of love. It was like a miracle! He suddenly came back with flowers saying that i should forgive him,i was truly flabbergasted and shocked when my husband kneel down begging for forgiveness and for me to accept him back..I'm really short of words and joyful,you are a God sent to me and my entire family.. And now I am a joyful woman once again.Thank you so much Dr. Miracle.
