Dynamic glacial landscape or tundra, in which there are many hours of sunlight during the summer, but very few during the winter; very humid summers but very dry summers because the water freezes and it is not available; short and temperate summers and very cold winters.

-It's located in Alaska, USA. Denali National Park includes the central, highest portion of the Alaska Range.To the north the park and preserve encompass the valleys of the McKinley, Toklat and Foraker Rivers, as well as the Kantishna and Wyoming Hills.

-Denali National Park and Preserve is located in the central area of the Alaska Range, a mountain chain extending 600 miles across Alaska. Its elevation of 20,310 feet makes it the highest mountain in North America. Its vertical relief (distance from base to peak) of 18,000 feet (5,500 m) is the highest of any mountain in the world. The mountain is primarily made of granite, a hard rock that does not erode easily; this is why it has retained such a great height rather than being eroded.
-There are three major rock provinces that run in east-west bands through the park. The oldest is in the north, and the younger ones in the south.
-The oldest rocks in the park are part of the Yukon-Tanana terrane. They originated from ocean sediments deposited between 400 million and 1 billion years ago. The original rocks have been affected by the processes of regional metamorphism, folding, and faulting to form rocks such as schist, quartzite, phyllite, slate, marble, and limestone.

Long winters are followed by short growing seasons. The weather is so unpredictable that there have even been instances of snow in August.
The north and south side of the Alaskan Range have a completely different climate. The Gulf of Alaska carries moisture to the south side, but the mountains block water to the north side. This brings a drier climate and huge temperature fluctuations to the north. The south has transitional maritime continental climates, with moister, cooler summers and warmer winters.
