The cache is in an ammo box and is easy to find. It includes a logbook, pens/pencils, lots of treasures, a disposable camera, and garbage bags (to encourage people to clean up on their way out). The area is home to rattlesnakes and black widow spiders, so use care in hiking.
The day we placed the cache we saw wild horses, a coyote, prairie dogs, and buffalo as we drove through the park on the way to the geocache.
