There is nothing hidden at the posted coordinates.
To find the coordinates, first complete the fantastic 'Old Town Pocatello' Adventure Lab - your reward is the coordinates to this bonus cache. This requires the adventure lab app but still uses the same geocaching account you are on right now.
The final is within 3 miles of the bogus coordinates so a car is handy. It is among sagebrush so be weary of ticks during summer months. The cache is placed with permission and has plenty of parking nearby.
