This earthcache and has no container. It is located on the Alaska highway at km1152 in Yukon Territory, Canada. You are looking at what remains of the ancient land of Quesnellia (Quin-ell-ia). Here, the volcanic Islands of Quesnellia have long since eroded but we can see the granite roots of a once-mighty volcano and the angular spikes of an ancient magma chamber.
Granite cooled in the earth’s crust 206 to 144 million years ago, during the Jurassic period of the Mesozoic era. Undersea volcanoes erupted above the granite. The granite base and volcanic islands of Quesnellia, were crushed against the westward-moving North American continental plate Please send the answers to the following questions to the cache owner. 1) What is the name of the lake at ground zero? 2) What plate was Quesnellia on? 3) How tall is Simpson Peak? 4) What is a terrane? 5) What is the elevation at ground zero? 6) Finally, even though pictures are optional, please post a picture of you and your party (or of your GPS if you are caching solo) for all to enjoy. Do not include the sign at the posted coordinates in your photo.
