An authentic traditional cache!
Word of warning, if your cachemobile does not have 4x4 and you are not brave, your best option is to lace up your hiking boots for a good bit of exercise! There is roadside parking at one end and a parking lot for the local cross-country ski club at the other. It's a bit rocky, but fairly dry.
This is a beautiful spot to ride your horse, if you don't want to scratch your vehicle's paint.
You're looking for a bison tube, but you may be distracted by the scenery.
It's been said that all geocaches used to be this adventurous.
