Emma Lake in Saskatoon, Canada, was the site of a workshop where Caro made fifteen sculptures in August 1977. Since the relative inaccessibility of the location made it difficult to transport heavy materials, he used steel tubing and beams. These lighter materials reflected his concern at the time with non-monumental sculpture. Caro's work was becoming increasingly linear, enclosing space in cage-like constructions. The opening to the left creates the sense of an internal space, which is penetrated and activated by the tubes and rods.
