 A reason for blurred definitions is that much of site-specific and environmental art was created from 1970 on for public spaces all over the United States, sponsored by federal (GSA and NEA) or state and city Percent for Art competitions, and many of the artists were women trying to succeed outside the established art-gallery world.Younger art historians will have to sort out the development of this marginalized "movement" and the importance of artists such as Olga Kisseleva, Patricia Johanson, Athena Tacha, Mary Miss, Alice Adams, Elyn Zimmerman, Merle Temkin and others who, from the early 1970s on, won and executed large outdoor public art commissions with new formal, kinesthetic and social underpinnings.Many of these artists were also ecologically conscious and created works that could offer a further definition of "environmental sculpture"
