Odd Rock

(Click to enlarge)

I'm a little bit of a geology buff, and so this rock near the top of Mount Washington caught my eye. It appears to be quartz, with pieces of graphite wedged in. The rest of the rock on Mount Washington is good ol' New Hampshire granite. A rock out of place is known as an 'erratic'. Normally, an erratic is taken from its home and deposited by a stream, glacier, or landslide. Gravity is involved. But at the top of the tallest mountain within thousands of miles, how did this get plopped down?
