More of the Story
If you would like to know more, the following will serve as a good introduction to the story of Isle Royale. You will see contradictions, so think about “facts” vs “what was the best information the writer had”. It is very interesting to read with an eye towards when each was written.
- 1934 by Adolph Murie
“University of Michigan Museum of Zoology, Miscellaneous Publications No. 25, “The Moose of Isle Royale”
“According to persons long familiar with Isle Royale, the last influx of moose occurred during the winter of 1912-1913. … it would not be surprising if the actual number of moose in 1930 proved to be two or three thousand.”
- 1936 event pointed to in a biography of Sigurd Olson by David Backes
“In 1936 Sigurd Olson was asked to chair a committee of the Ecological Society of America to promote the introduction of wolves to Isle Royale.” from “A Wilderness Within: The Life of Sigurd F Olson” (only page 122 is referenced here).
