Joshua Tree National Park This beautiful gem of Southern California was the destination for our 2004 field trip. We focused on the higher elevation, Mojave Desert portion of the park. SDAG members camped in the park and visited several geologic, mining, and cultural points of interest. Dr. D. D. Trent, co-author of "Joshua Tree National Park: Geology" joined us on our trip. Note that Sunbelt Publishing has copies of Dr. Trent's book (with Dr. Richard W. Hazlett, 2002) for sale! Contact Lowell Lindsay at

Joshua Tree shadow John D. Clark was born in 1957 and grew up in rural Maryland. For a family trip to Washington D.C. in 1974 he borrowed a 35mm camera from his science class and was hooked on photography. While following a career in chemistry, he returned to his love of photography. John's first large format camera was home-built from a kit and he currently uses both 4x5 and 8x10 view cameras. The view cameras allow John to create the landscape photographs that he enjoys searching for in the highest quality possible. The photographs were made with either a 4x5 or an 8x10 camera on traditional black and white film. The sheet films are individually developed by hand and prints are hand-crafted by John in his own custom darkroom in Oceanside, California. There are no automated processes, no lab assistants, no machines involved. More of John's work can be seen at
