Armchair Pirate's Ship of Stone!

Actually, this is Arizona's Hickey Formation. The Hickey Formation is the name given (by geologists) to a sequence of basaltic flows and associated red-brown sedimentary rocks exposed on the east side of Estler Peak in central AZ. The Basalt volcanism part of the formation is dominantly subalkaline (a rock that contains no alkali minerals other than feldspars). The lower sedimentary part of the formation consists mainly of conglomerate, sandstone & siltstone interbedded with olivine basalt. At first glance, this DOES resemble the prow of a pirate ship made of stone. What's that you say? You haven't a clue what a PIRATE is, mate??? Please CLICK! December 13, 2008
