You may want to bring your gloves for this one (and no, not your white kid opera gloves). This is the bonus cache for the nearby Adventure Lab "On the Trail With Estes Park's Mountain Women." You get the coordinates by completing that AL, of course. You can access that Adventure Lab at https://adventurelab.page.link/f5M5
The cache is a small camouflaged bison tube in vegetation. There is not room for trackables or swag. It would be nice to hide a bigger cache in this area, but it is very busy much of the year and several previous caches have quickly gone missing. Here's hoping that this location discourages random Muggles enough.
There is parking very close to the cache. Practice stealth (practice stealth, practice stealth!). You can check out the hint and it might save you some digging around.
