The cache is located near a trail constructed by the women of the
nearby Fire Crew 13 facility.
The name of this trail is "Agony." And from the location of the
cache, a tall person can see the Backbone Trail a little way below,
hence the name "Bagonybone."
There are several ways to get to this point on the trail. You
can come from the west, starting on the Backbone Trail where it
crosses Encinal, and turning down Agony, and then climb that hill.
And if you're looking for a real challenge, try running up it!
The easiest way is probably to come from the east, where it
intersects the Backbone Trail.
The most interesting way is to come along the trail with the
"Crew 13" cache. Trailhead and parking information is on that cache
page.
