Dwarves' Earth Treasures Museum:
Friend Ranch Thundereggs
Friend Ranch, Ashwood, Oregon
.
  I was informed that the owner of Friend Ranch has died (Jan 2009) and the ranch is currently closed to any further collecting/digging expeditions and its future is uncertain.
     The Friend Ranch is one of few fee-basis rockhounding site that is still open to any people and the thundereggs found there has very rough and prickly appearance making them not quite look like the typical thundereggs of Oregon!  The "prickles" are the streteched porphyic feldspar crystals sticking out of the thundereggs and the feldspar crystals had formed in the magma first before it erupted. The crystals were preserved by the growth of cristobalite forming the thundereggs after the rhyolitic lava have cooled.
    The thundereggs contain at least two different types of agates. It is more common to find those with colorless agates sometimes with black swirls while many others contain more desired color combo of blue, black and rarely red that are not resticted to the bands. Such distributation of colors can produce the patterns reminding of any objects like face, ghost, animals, whatever (Aparitions).

Rough Appearance: Gray with light stretched feldspar crystals sticking out (dead giveaway), often with yellow/rusty streaks along the ridges.
Will come with either clear agate or blue agate sometimes with white, black and red colors..
Is there a ghost in one of those thundereggs? Black Pac-Man!
