Geography

Situated in the wide valley of the Yukon River and the Yukon Southern Lakes Ecoregion, the geography around Whitehorse is characterized by broad valleys and large lakes.  It is surrounded by three nearby mountains: Grey Mountain to the east, Haeckel Hill to the northwest and Golden Horn Mountain to the south.

Permafrost underlies less than one-quarter of the landscape in this ecoregion; east of Whitehorse, less than 8%of the Alaska Highway is built on permafrost.

This ecoregion also supports the highest diversity of mammals in the Yukon, with at least 50 of the 60 species known to occur in the Yukon at present.

The weather in Whitehorse ranges from sunny, warm summers to cold, snowy winters. In summer, the temperature can be plus 30 Celsius and the hot spot of Canada while in winter it can drop to minus 30 Celsius.
