The coolest xenolith ever! (prove me wrong!)

For those non-geologists amongst you, imagine a mass of molten rock, deep under the earth's surface. As it moves into place, it disturbs the rock that was surrounding that area. A xenolith is a chunk that fell in and was preserved without melting. This one is so cool, I think, because it is such a darker color and has that spectacular, squiggly quartz dike within. The xenolith is ~40 cm high.
