Towards the end of 2015, James Benning made one of his occasional expeditions to Utah, to the place where Robert Smithson's colossal land-sculpture Spiral Jetty (1970) extends out into the Great Salt Lake. The water-level was low, leaving the vast bulk of the Jetty exposed in the crisp air. His film measuring change captures two thirty-minute periods of that particular day, in the unblinking, unmoving takes that have become his trademark––beginning at 8:57am and 3:12pm respectively. A belated digital companion piece to his 16mm masterpiece casting a glance (2007), this new film hypnotically contemplates Smithson's art-work in relation to its wider environment and to the humans who walk on and around its gargantuan coils.
