Nature and Science - Geology and Minerals
A study of the geology (landforms, rocks and minerals) of the Tongass and Chugach National Forests is foundational to our understanding of the forests. Geology reveals the history of the earth, including the landforms, rocks and minerals so prominent on the Tongass and Chugach. The surface and subsurface minerals provide valuable commodities for human use. Extraction of those minerals is not only significant today, but has been an integral activity in the history and development of both forests. Broken down, as components of soil, these minerals also provide basic nutrients and elements for forest plants and animals.
