Sometimes you just need a quick pit stop. This should provide one for you. The cache is located next to Spring Creek just off the intersection of Highway 385 and Calumet Road heading to the Sheridan Lake Recreation Area (South Unit). There's plenty of parking right off the road, and it's a short stroll over to the cache. You're looking for a simple bison tube, hanging around waiting to be found. If there are non-cachers also "hanging around" the area, you might consider holding off and coming back a bit later, if possible.
There's no need to tear anything up or destroy the area to find this, it's right there in front of you at pretty much eye level. Enjoy the area, and have fun!
