The main purpose of this legislation is to officially change the name of Camp Nelson Heritage National Monument to Camp Nelson National Monument. This change aims to simplify the name and enhance the recognition of the site. Key provisions of the legislation include specific amendments to existing laws that govern the designation of the monument. It involves removing the word "heritage" from the name in various legal references and documents. This means that all mentions of the monument in laws, maps, and other official records will now refer to it as Camp Nelson National Monument.
