Geocache Description:

Congratulations Wal-Mart Man. txlabguy and CoolInTexas for the co-FTF!

This is the last of 4 caches representing the largest moons of Jupiter.
**This is a puzzle cache. There is no cache hidden at the posted coordinates.**
**You use the values found in one of the other 3 Galilean Satellites caches to compute the true coordinates.**
Ganymede
Ganymede [GAN-ee-meed] is the largest moon of Jupiter and is the largest in our solar system with a diameter of 5,262 km (3,280 miles). If Ganymede orbited the Sun instead of Jupiter it could be classified as a planet. Like Callisto, Ganymede is most likely composed of a rocky core with a water/ice mantle and a crust of rock and ice. Its low density of 1.94 gm/cm 3, indicates that the core takes up about 50% of the satellite's diameter. Ganymede's mantle is most likely composed of ice and silicates, and its crust is probably a thick layer of water ice.

Ganymede has no known atmosphere, but recently the Hubble Space Telescope detected ozone at its surface. The amount of ozone is small as compared to Earth. It is produced as charged particles trapped in Jupiter's magnetic field rain down onto the surface of Ganymede. As the charged particles penetrate the icy surface, particles of water are disrupted leading to ozone production. This chemical process hints that Ganymede probably has a thin tenuous oxygen atmosphere like that detected on Europa.

The correct coordinates are:
N  33 02.[134 + A]
W 096 40.[B - 145]


This cache started out with some blank CDRs, a compact battery charger w/ 2 rechargable batteries and some 33mm containers that can be used to create new hides.

You will have to leave the beaten path to find this one. Be careful of thorns, (PI in season) and dropoffs. Please hide the cache as good or better than you found it.

Additional Hints (No hints available.)
