Denali Education Center Executive Director Willie Karidis began his 70-day winter expedition to retrace, research and celebrate the steps of pioneering naturalist Charles Sheldon on Tuesday, January 22, 2008. The trip has been a dream of Willie's for over twenty years, since he first read "Wilderness of Denali". That book chronicles Sheldon's experience as he spent the 1907-08 winter in the heart of the Alaska Range along the banks of the Upper Toklat River. It was during that time that he had a vision for a National Park to preserve the unique natural ecosystem he experienced for future generations. Willie is working as a park volunteer (VIP) during his expedition and is being provided support by the National Park Service. Willie planned to camp in the v...

Watch the glaciers of Kenai Fjords transform before your eyes as nearly a century of change is revealed by repeat photography. Dr. Bruce Molnia, glaciologist with the U.S. Geological Survey, has been conducting repeat photography research throughout Alaska for the last decade. His work in Kenai Fjords National Park focuses on photographs shot in 1909 by U.S. Grant and D.F. Higgins. Between 1905 and 1909, they completed the first detailed survey of the glaciers of Prince William Sound and the Kenai Fjords coast. Their photographs, archived in Denver, Colorado, provide an opportunity to document a century of change. With support from the Park Service motor vessel Serac, Molnia traveled the Kenai Fjords coast, duplicating the 1909 photos. Using clues such as mountain ridge lin...

The Shamrock Glacier in Lake Clark National Park and Preserve, Alaska, USA, has receded about 2 miles from its 1928 position near its terminal moraine. Some newly exposed morainal surfaces are now vegetated. 1928 photograph by Stephen R. Capps. 2004 repeat photography by M. Torre Jorgenson. The Southwest Alaska Inventory & Monitoring Network (SWAN) is an office of the National Park Service dedicated to providing the scientific foundation for effective, long-term protection and management of natural resources in five units of the national park system. Collectively these units comprise approximately 9.4 million acres, 11.6 percent of the land managed by the National Park Service, or 2 percent of the Alaska landmass, and include a diversity of geologic features, eco...

Climate Change ‘Magic’: Disappearing Lakes and Reappearing Artifacts In the summer of 1999, artist Hamish Fulton took a hike through the icefields of Wrangell-St. Elias National Park and Preserve (WRST). One highlight of his journey was a traverse near Iceberg Lake on the Bagley Icefield. Imagine his surprise when he crested a low pass expecting to see the lake, but all that remained was a small creek emerging from the melting terminus of a small alpine glacier. Icerberg Lake had disappeared. While in another area of WRST, scientists were discovering rare archeological materials melting from ancient glaciers. How and why these events happened is covered in the latest issue of Alaska Park Science. The tenth issue of Alaska Park Science, entitled “S...
