About 12 years ago, I paddled and camped along the Peace River with some friends. On that trip, many people were using screens to find fossilized shark teeth and such. (I just floated along and took pictures.) Back at camp that evening, someone at the campground was showing off his find: a mammoth tooth! And part of a mammoth jaw bone! Through the grapevine, I heard this person found more related bones, and his collection went to the state natural history museum — but I can’t vouch for that info 100%.
