Nature Notes

Grand Canyon began issuing the bulletin Nature Notes in 1926, the purpose of which was “giving information to those interested in the natural history and scientific features of the Grand Canyon National Park.”

Ranger Naturalist Glen E. Sturdevant served as editor and primary contributor to Nature Notes until his death in February, 1929 (see Volume 3, No. 8), after which Edwin D. McKee took over, serving both as editor and new Park Naturalist.  The bulletin was issued monthly by the park until 1931, when the Grand Canyon Natural History Association took over the publications, which continued until 1935.  Below are PDF versions of Volume 1, No. 1 through Volume 6, No. 5.  Later editions can be found on the Grand Canyon National Park Website here.
