   So, you want to see the beautiful
of "The Boulders" up close?
   This is a polished section, at a magnification of about 3x.  The majority of what you see is a mineral called feldspar, some of the gray crystals (clear, in reality) are quartz, and the black ones are a type of mica called biotite.
   These minerals cooled from a molten state about 1.4 billion years ago, during time.
   The shapes of the boulders you see now behind the lodge are much, much younger.  They have been formed by fracturing and erosion over the last 12 million years or so, and actually are still in the process of formation -- slowly, slowly.

   You can ponder these facts while playing golf at one of The Boulders' famous courses!  Or you can take one of our weekly hour-long tours up into the rocks.  Just ask at the Concierge Desk.
