Day 117: a geode

27.04.14: yeah, I had to look this one up before I began. Wikipedia describes them as 

"Geodes are geological secondary structures which occur in certain sedimentary and volcanic rocks. They are themselves of sedimentary origin formed by chemical precipitation."

     For us normal mortals, they basically are beautiful crystals found within volcanic rocks... Or something like that... 

     Why I decided to throw inJon's secretary, Miss. Hills, in the background, I could not tell you...

 

     And starts another week. Have a great week.
