Disclaimer: With the exception of corrections to a few grammatical errors (to improve readability), Nature Notes is reproduced as it was originally published. Much has been learned about the natural history of Crater Lake National Park since these notes were first published, rendering some of the original conclusions inaccurate or invalid, just as determinations of today may be rendered "obsolete" 50-60 years hence. The reader is advised to consult more recent literature to obtain a current understanding of the topic.
