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.
