This is the second of a series of bulletins issued monthly during the season to give information on subjects of interest concerning the natural history of Crater Lake. It is supplemental to the lectures and field trips conducted by the Park naturalist.
Publications using extracts kindly credit the bulletin and author.
For copies, which are free, address the Superintendent or Ranger-naturalist. This online edition of Nature Notes from Crater Lake does not contain the artwork, photography, charts and diagrams which greatly enhance the hardcopy edition. The reader is advised to consult more recent literature to obtain a current understanding of the topic. In the last issue of these notes, the evidences that a mountain did exist where Crater Lake now lies, were discussed. It may be claimed that no mountain existed and that the crater as it was now lies before us.
