Hauser Bed Thunderegg Polished Rock Large Geode Stone
This is a larger Hauser Bed Thunderegg from the famous Hauser Geode Beds located in the Wiley’s Well rockhound district (near Blythe, California).
This thunderegg half has been cut and polished on one face, left rough on the back. It has nice blue fortification agate and a solid crystal center.
It is 6 inches by 5.2 inches and 2.2 inches at its thickest.
Joel Hauser-first discovered the Hauser Hole- later renamed the Potato Patch, in the 1930's. After all the thundereggs on the surface were collected, people thought it was played out. So, in 1937 Joel went to the west side of the Black Hills and worked his way east in search of new deposits. He discovered the Hauser Geode Beds, which soon became far better known than his first discovery. Although they are less than one air mile apart, today the Potato Patch and the Hauser Geode Beds are correctly viewed as two separate and distinct collecting areas, mainly because the thundereggs they produce are different.
A Thunderegg, is a spherical geode rock with a rough and unappealing surface, but when cut in half is filled with agate, jasper, quartz and/or other minerals. Typically, they are about two to six inches in diameter, although very large ones have been found!
Thundereggs were formed in the rhyolite lava flows and tuffs within the gas or steam pockets that served as molds. The pocket cavity was filled with silica-rich fluids and later solidified and crystallized. Mineral impurities are collected along the bands creating concentric colorful rings.
The name “thunderegg” is believed to have originated from Native American folklore. Native American legend reportedly considers the rocks to be the eggs of the thunderbirds which occupied Mount Hood and Mount Jefferson. Thunder Spirits on the mountains hurled the "eggs" at each other.
