Treasure Legends Klamth falls area?

[DPS]

I am very interested in learning about any lost treasure legends or interesting historical stories from the Klamath Falls area, especially around Bonanza, Langell Valley, and the surrounding countryside?
I have always been fascinated by local history, lost treasures, and old stories that may have been passed down through the years.
If anyone knows of any interesting legends, forgotten stories, or good books on these subjects, I would greatly appreciate any information or recommendations.
Thank you very much for any help or suggestions.
