A Legacy of Our Search for Mineral Wealth

Abandoned Mineral Lands (AML) include old mines and oil wells, buildings and foundations, and equipment and tools. There are many hazards at AML sites that need to be addressed, but they are also important as cultural resources and habitat.

Deserted, these sites stand in silent testimony to those who pioneered this country in search of wealth and freedom. Learn what the National Park Service is doing with AML and how you can help.
