Begins the series Drawing Which Makes Itself, inspired in part by her visual memory of the track marks skiing through fresh snow. She believes that experience added significantly to her knowledge of line and drawing and using the body. Her study of topology with Max Dehn at Black Mountain College would help her to incorporate this idea into her work.
Building upon the series Drawing Which Makes Itself, she executes the Locus Etchings with Kathan Brown at Crown Point Press in San Francisco.
The Locus Etchings shown at the Stadtiches Museum (later, in 1981 at the Museum of Modern Art).
In April, she exhibits at Galerie Sonnabend in Paris, France.
That summer, she is invited to Argentina for a one person exhibition and to participate in a group show at the Museum of Modern Art in Buenos Aires. She travels to Brazil and Peru. Marvels at the archeological sites. This stacking influence is incorporated into such future work as Leveling and Scalar.
Shows Intersection in the group show, “Art of the 20th Century” at the Stedelijk van Abbemuseum in Eindhoven, The Netherlands. Joseph Beuys, also in the show, assists with the installation of this work.
Participates in two group shows at Bykert Gallery with Lynda Benglis, Porfirio Di Donna, Sol LeWitt, Brice Marden, Robert Ryman, and Richard Tuttle, Jan Dibbets, Agnes Martin, Eva Hesse, Ralph Humphrey, David Novros, and Alan Saret.
