Land art is made directly in the landscape by sculpting the land itself or by making structures in the landscape with natural materials. - Utah Museum of Fine Arts

I've expanded the definition to flexibly include works of art that explicitly interact with the landscape, are site-specific, usually relate to nature, and / or reject the traditional art system and their status as traded commodities. Look it’s my blog, I can do what I want! I waffle on whether or not it should be conserved or fully returned to nature.
