In April 2008, Gregg Treinish became one of the first two people to trek the length of the Andes Mountains, south of the equator — a journey that lasted nearly two years and 7,800 miles. Following the spine of the longest mountain chain in the world, he and Deia Schlosberg traveled to remote and often never-before-visited villages in the Andes. They experienced first-hand the lives of a people who have been living for centuries using sustainable methods.

Through intimate journal entries, stunning video, and captivating slides, Mr. Treinish will bring visitors to Wilton Library along for the journey on Tuesday, May 21, at 7 p.m. Mr. Treinish’s appearance is part of the Green Speaker Series, presented by Wilton Go Green, the Norwalk River Watershed Association and the library. He will be joined by international photographer Daryl Hawk, who recently completed his own trip to Argentina, in an interview format.

Mr. Treinish and Ms. Schlosberg were named National Geographic “Adventurers of the Year” for their endeavors. Today, Mr. Treinish is the founder and executive director of Adventurers and Scientists for Conservation (, a nonprofit organization focused on bringing the adventure and science communities together. He believes it is the responsibility of those who use natural areas for recreation to protect those same areas.
