Thanks, Longhorn, glad you like it.
Smoke, I hope you do get to visit these places some day.
Foy, "laccoliths", thanks, I'll try to remember the scientific term. "The word laccolith derived in 1875—1880, from Greek, lákko(s), meaning pond, plus -lith, meaning stone." - wikipedia. So, lake stone, now with a mnemonic I'll have a better chance of remembering. ;-)
