Here's a series that will hopefully be winter friendly (depending on snow levels).
Most of them will involve a short walk, hike, or perhaps a trudge through snow!
Sadly, the "mystery" Bonus Bones cache is no longer active, so the numbers you see on the bones are no longer pertinent. Please enjoy the caches for themselves.
(As with most bison tubes, please replace the log paper into the LID before screwing on the bottom.)
Head out towards Casino to find this "Lazy Bones" cache. Lots of parking at the dumpster!
