Kluane / Wrangell-St. Elias / Glacier Bay / Tatshenshini-Alsek

This site is an international park system that comprises 4 parks located in Canada and the U.S. This first postcard is identified as part of this park system in Canada but it doesn't say exactly which park it is.

Kluane/Wrangell-St. Elias/Glacier Bay/Tatshenshini-Alsek

 This postcard was sent by Natasha

These parks comprise an impressive complex of glaciers and high peaks on both sides of the border between Canada (Yukon Territory and British Columbia) and the United States (Alaska). The spectacular natural landscapes are home to many grizzly bears, caribou and Dall's sheep. The site contains the largest non-polar icefield in the world. - in: http://whc.unesco.org/en/list/72/

Mt. Logan in Kluane National Park

This postcard was sent by Steffi

Mount Logan is the highest mountain in Canada and the second-highest peak in North America, after Denali.

Mount Logan is located within Kluane National Park and Reserve in southwestern Yukon, less than 40 kilometres (25 mi) north of the Yukon/Alaska border. Mount Logan is the source of the Hubbard and Logan Glaciers. Logan is believed to have the largest base circumference of any non-volcanic mountain on Earth (a large number of shield volcanoes are much larger in size and mass), including a massif with eleven peaks over 5,000 metres (16,400 ft). - in: wikipedia

The glacier begins on the southern slopes of Mount Root, elevation 12,860 feet (3,920 m), on the Alaska–Canada border flowing southeast down the valley, then turning to the northeast toward its terminus in Tarr Inlet. - in: wikipedia
