All of you guys answered correctly in your own way but no one exactly provided the source of the pair's original fame. I just finished reading GREAT WYOMING BEAR STORIES by Tom Reed. This book is well documented and actually I know quite a few people mentioned. Nevertheless, Pope and Young were employed by the California Academy of Sciences in 1920 to hunt Yellowstone National Park for a grizzly family to be passed off in the museum as extinct California Grizzlys. They were supposed to use rifles to collect three bears even though hunting in the park was outlawing in the 1880's. Political connections in Washington allowed their activity. They sneaked in their bows and arrows and managed to pincushion numeous bears which did not bother the hunters in the least. After all they were POACHING well beyond the original three bears. This story was widely published in magazines and journals of the era. I was very much surprised to learn of these guys obviously well known unsportsmanlike behavior.
