Working alone, Wark has photographed the continent from Alaska to Labrador in the north; and from Costa Rica to the Lesser Antilles in the south. In eleven years he has flown more than 5,000 hours, and taken more than 100,000 photographs. To guide him, he uses aviation skills gained as a Naval Aviator and airshow pilot, and a love of the earth and its forms gained from a career as a mining engineer and geologist. The photography is represented by photo agencies in the U.S., U.K., France, and Australia. Membership is maintained in ASMP (American Society of Media Photographers) and PAPA (Professional Aerial Photographers Association). His work was judged "Best of Show" by PAPA for four consecutive years (1995-1998). See less
