French artist Pierre Huyghe has transformed the roof of the Metropolitan Museum of Art into what resembles an archaeological dig site.

The living installation is this year's roof garden commission, opening to the public on Tuesday.

A hunk of Manhattan bedrock rests among the roofas granite tiles, some removed to expose the Earth and activity underneath.

The focal point of the work is an aquarium that features a floating granite rock and ancient aquatic critters such as American tadpole shrimp a living fossils that have existed in nature for over 220 million years.

"Part of this exhibition is about a history that extends far beyond our imagination, to something very distant in time," curator Ian Alteveer said at a press preview yesterday.

The installation will be on display through Nov. 1, weather permitting.

The always popular Roof Garden Cafe also reopens for the season today, along with the martini bar on Friday and Saturday evenings.
