Crater Lake's Merriam Cone is an underwater cinder cone—hidden from view in contrast to Wizard Island (another cinder cone), which can be seen from almost any place on the rim, including the Sinnott Memorial Overlook at Rim Village. While volcanic Wizard Island is named for its resemblance with a sorcerer's hat, the underwater volcano is named in honor of John Campbell Merriam (1869-1945) [1-5].
Merriam was a paleontologist, conservationist and educator. He achieved scientific prominence at UC Berkeley, California, from where he led expeditions to study fossils in California, Nevada and the Pacific Northwest. In Oregon, he was influential in turning the John Day Fossil Beds into a state park. In the 1920s, Merriam became director of the Carnegie Institution of Washington, fostering scientific research. There, he tapped Carnegie money to augment federal funding for the Sinnott Overlook with its educational exhibits. Merriam viewed the dramatic landscape of Crater Lake National Park as a “superuniversity of nature,” inspiring and educating visitors . Stephen R. Mark writes :
For Merriam, Crater Lake stood out as a superb case study, an opportunity to show how a scientist could develop a formalized program of “interpreting” nature for the general public.
Today, “nature & science lovers” can find various interpretive sites at Crater Lake, but also uninterpreted ones to test their own knowledge and skills in appreciating and understanding creation through natural processes—geological processes reshaping our dynamic Earth.
