Climate
The climate is typical of the Northwest. It is easy to stereotype the weather there as heavy, rainy winters and clear, mild summers. As with any outdoor recreation area, however, it is important to remember that inclement weather can occur at any time of the year. It's is not unheard of to have snowstorms in July at higher elevations!
Perhaps the most astonishing climatological occurrence in the the park is that it is home to the world record snowfall. In 1999, Mt. Baker received 1140 inches of snow. That's over 90 feet! Also Keep in mind that as soon as one crosses the Cascade crest, the climate becomes that of the eastern Washington high desert.
Flora and fauna
The park is home to a wide variety of species, most notably the Grizzly, the Gray Wolf, and the Canada Lynx. The extreme variation in elevation produce an incredible range of plant life as well, with the short flowering season of the alpine meadows being particularly spectacular.
Landscape
The park ranges from lowland valleys to rugged alpine peaks. There are two large lakes within the complex as well, Lake Chelan and Ross Lake.
