Craters of the Moon National Monument and Preserve is a testament to the dynamic geological history of Idaho. Established in 1924, this area has undergone significant changes and expansions over the years.
Managed by the National Park Service and the Bureau of Land Management, it now covers over 1,100 square miles. This article explores the historical development and expansion of this unique national monument and preserve.
Establishment in 1924
The journey of Craters of the Moon as a protected area began on May 2, 1924, when it was established as a national monument. The initial designation aimed to preserve the "weird and scenic landscape" of the area, which was recognized for its unique volcanic features and formations. The monument was created to protect the extensive lava fields and volcanic cones that characterize the region.
The establishment of Craters of the Moon was largely influenced by the work of individuals like Robert Limbert, who explored and documented the area in the early 1920s. His efforts to raise public awareness and appreciation for the region's geological wonders played a crucial role in securing its protection as a national monument.
Expansion in 2000
In November 2000, a significant expansion of Craters of the Moon was enacted through a presidential proclamation by President Bill Clinton. This expansion increased the size of the monument by 13 times, bringing the total area to over 1,100 square miles. The expansion aimed to encompass the entire Great Rift zone and its associated lava fields, ensuring the protection of these important geological features.
The expanded area included the addition of the Kings Bowl and Wapi lava fields, both of which are approximately 2,200 years old. These fields are part of the National Preserve, which was designated in August 2002. The expansion also included about 400 square miles of sagebrush steppe grasslands, further enhancing the ecological diversity of the monument.
Management and Preservation
Craters of the Moon is managed cooperatively by the National Park Service and the Bureau of Land Management. This joint management approach ensures the protection and preservation of the area's unique geological and ecological features. The monument and preserve are located in parts of Blaine, Butte, Lincoln, Minidoka, and Power counties, highlighting the regional significance of this protected area.
The expansion and management of Craters of the Moon reflect a commitment to preserving the natural and geological heritage of Idaho. The monument serves as a valuable resource for scientific study and a destination for visitors seeking to explore its unique landscape. As a protected area, Craters of the Moon continues to offer insights into the volcanic history of the region and the forces that have shaped its landscape over millennia.
