Change is ever-present in natural settings, and the landscape of Denali is no exception.
Over the course of a day, flowers open and close as light plays on mountain flanks. Across the seasons, lakes and rivers freeze and thaw. And over thousands of years, glacial advances literally carve the landscape we see before us. Although many changes are natural and can be expected, Denali's landscape may also be imperiled by changes - those brought on by human activities.
Human impacts can be seen most clearly in direct alterations of the landscape caused by infrastructure development, but there are also less obvious impacts resulting from our modification of the earth's climate system.

Climate Maps for Alaska
The PRISM (Parameter-elevation Regressions on Independent Slopes Model) climate mapping system was used to generate these products. This mapping system integrates existing climate station data with scientific understanding of general climate processes and local climate features. These climate maps feature a 30-arc second (approximately 800 meter) grid size resolution for the state of Alaska.
To obtain complete data sets, visit the NPS Data Store.

Mount McKinley, located within Denali National Park and Preserve, is the highest mountain on the North American continent. Measured from the 2,000 foot lowlands to its snowy summit at 20,320 feet, the mountain’s vertical relief of 18,000 feet is greater than that of Mount Everest.
