Stephanie Straight, a freshman at St. Joseph's College, works on a natural materials sculpture by artist Patrick Dougherty in front of Pao Hall at Purdue University in West Lafayette, Ind. Tuesday, March 22, 2011.

North Carolina-based artist Patrick Dougherty has gained an international reputation for his natural-wood structures and has created hundreds of monumental, site-specific sculptures around the world. His work is constructed from saplings gathered from local sources and shaped into massive, swirling forms as high as 40 feet. In his work, Dougherty combines his carpentry skills with his love for nature. In the early 1980s he began incorporating primitive techniques of building and experimenting with tree saplings as construction material.
