The Prospect Park Alliance and ArtBridge have collaborated to transform 300 feet of construction fencing in Prospect Park into a large-scale, outdoor photo installation. Natural Disruptions features the work of two Brooklyn artists, Mark Dorf and Anthony Goicolea.

Through digital manipulation, Dorf and Goicolea slyly alter our understanding of nature. Goicolea’s landscapes are like snapshots from a playfully dark daydream. Dorf’s work questions the ways that science and the Internet define our relationship with nature.

The installation will cover construction fencing at the historic 1869 Wellhouse, one of Prospect Park’s oldest structures, which originally served as a pump house for the Park’s water supply. The Prospect Park Alliance is transforming the building into public restrooms featuring composting toilets—the first to be installed in a New York City park.

Natural Disruptions will be on view from September 30, 2015, through Summer 2016. In addition to the Wellhouse, the exhibition will continue along Wellhouse Drive at Terrace Bridge, adjacent to the Park’s new Sunday Smorgasburg event (which runs through October 11). The photo installation consists of more than 40 artworks, running 300 feet along Wellhouse Drive, and ranging from 6 to 8 feet high.
