If you look on the trail map and find the box on the lower left corner for trail conditions and look to the right of the box you will find section 17. also on the map you will see road 296 veering to the North in section 16. Up to that point 296 follows along the North side of a wide open canyon. Instead of following 296 North follow the Canyon West. There is a faint 2 track through the middle. After leaving 296 you will go approx. 1 mile and the canyon will get narrower and will turn to the South. Immediately look to your Left to find snowmobile tracks going up the hill through the trees. towards the top there will be a bare spot that has been used as a turnaround. The cave will be just below that turn around. There are no signs for the cave.
