There is a large "B" painted on a hillside above Henderson.
Beneath it runs a paved bike trail that is one section of a future
31-mile biking/jogging/equestrian loop circumnavigating the River
Mountains. The path runs through mostly empty desert along the base
of the mountains and is virtually unknown, even to local area
cyclists.
The north end of the trail crosses under Lake Mead Drive near
the entrance to the Lake Las Vegas resort. A large dirt parking
area can be found at N36° 04.778'; W114° 56.018'. Entering from
this end, the trail is totally paved and suitable for street
bikes.
Near the south end of the trail, the pavement passes the water
treatment facility located in the desert east of Boulder Highway
between Henderson and Railroad Pass. There is a large paved parking
area at the south entrance to the trail. You'll find it near the
intersection of Equestrian Drive and Magic Way (N36° 00.822'; W114°
56.350').
As noted, this multi-cache is designed primarily for bicyclists.
Although the coordinates of the first leg are closer to the south
end of the trail, the interim legs will pretty much take you from
one end to the other. A quick look at the lay of the land will tell
you that it is mostly uphill coming from the north; which means
it's all downhill coming from the south. Patty recommends doing the
hard part at the beginning so you can coast home!
The interim repositories are small Altoid tins that contain
nothing but directions to the next leg. The final stash is a medium
sized ammo can that is (at least initially) stocked with some
pretty nice stuff. Be sure to re-cover all caches completely.
They'll still be easy to find, given the hints and coordinates, but
we need to keep them from being noticed by utility workers and
passers-by.
Update 4/13/2011: The second interim stash has been lost. I
eliminated it so that the coordinates provided in the first one
send you directly to the final one.
