1852
in the mid 20th-century there was a cultural shift in wilderness ethics from woodcraft where wilderness travelers prided themselves on their ability to rely on the resources of wild lands to a post-wwii ethics of minimal impact on the environment. leave no trace began in the 1960s and 1970s. there was a large increase of wilderness visitation following the creation of new recreational equipment such as white gas stoves, synthetic tents, and sleeping pads. this began a commercial interest in outdoor recreation which in turn caused more visitors to national parks. in those decades, the united states forest service, the bureau of land management, and the national park service started to teach their non-motorized visitors how to have a minimal impact on the land. wilderness informational specialists were trained to educate visitors on minimal impact camping in the different parks. in 1987 the three departments cooperatively developed a pamphlet titled "leave no trace land ethics".
