Burnt forest 15th June 2004 along Rocky Point Trail, McDonald Lake region, Glacier National Park, Montana, USA. This photo vividly shows a burnt forest. The forest fire happened one year ago in summer 2003. Some rare woodpeckers only inhabit recently burnt forest; the burnt forest also provides a chance for botanist to study plant succession in a dramatically altered ecosystem, and for geologists to study the landscape without being covered by vegetation.
