Pluto

In this model, the Grouse Ridge Lookout represents the Sun, and each “cache” represents the location of a planet at its scale orbit. The lookout building is the correct scale size of Sol for this model – 14.4 feet across. (Ok, so it’s a square Sun, sorry!) Some caches have a reference stick – a tagged object in the cache of the correct size – but please bring a measuring tape or something to use (reference sticks have been known to wander off!)

Please Note: Most of this series lies above 7000 feet. The caches are under snow from about November to late May.

Geocache Listing

This is at Drum Forebay, next to the inlet.  The cache is at the base of a tree. View Sol from N39 15.124′, W120 44.934′ (not at the cache.)

It can be difficult to locate Sol – very small at this distance.  Here’s a trick: find the cache, then set your GPS to find Sol (N39 23.178′, W120 36.759′, waypoint GCG3AG.) That will give you the heading you’ll need to pick out Sol with your binoculars!

There is an intense waterfall – the forebay inlet – very near the cache location.  It is fenced for safety, but prepare to exercise judgement with children.
