Baker Ranch Agate Polished Thunderegg Slab Deming New Mexico
A Baker Ranch Agate thunderegg from the famous Baker Egg Mine near Deming, New Mexico.
This large thunderegg polished slab is 8.5 inches by 6 inches and .68 of an inch thick.
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 or even crystal pockets! 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.
There are several thunderegg collection sites within "Baker Ranch". One of the better-known mines in this area is The Baker Egg Mine. The Baker Egg Mine is located in Luna County, about 28 miles southwest of Deming, New Mexico. This mine, discovered in the 1950's, is famous for its colorful thundereggs, which are uncommon.
The eggs have been mined from the surface down to sixty feet. They are commonly formed in smaller pockets, as opposed to a larger flow.
