I just heard of this today on a tv documentary, I wish I could visit. The centre covers a vast rural area one hour north of Manhattan. It was established in 1960 by Ralph E. Ogden and its collection has been growing ever since. The image above, belongs to one of the most prominent works -in my opinion- of Menashe Kadishman and his 1977 collection “Suspended”:

With no visible evidence of the engineering holding the sculpture up, Suspended prompts contemplation of the relationship between its two conjoined, towering masses, coupled with questions about what lies below ground. Rich and rusted, the patina of the weathered steel wraps the stark geometric shapes in a skin-like sheath.

Excerpt from The Storm King Art Center webpage

The center also accommodates many of the works of Mark di Suvero, among which “Mother Peace” (image below), a work completed just before Di Suvero left the US to protest against the war in Vietnam.
