Dugway Thunderegg
Dugway Range, Tooele Co., Utah
 .
     Locally called as "Dugway Geodes", the Dugway Thundereggs are one of well known and locations in the western states and they have been dug for many decades. Coming from the clay layers (decomposed pertile lava beds), the thundereggs are generally large sized geode-types with sugar-like quartz crystals lining the blue to lavendar agate rims. It is rare to find the thunderggs containg solid and well banded agates and purple color is supposed to be a rare color. It is not known how much percentage of the Dugway thundereggs contain solid agate or geodes since it's common for them to focus only on the hollow thundereggs that feel quite light for their sizes while heavier thundereggs with solid agates may have been ignored.

Rough Appearance: Brown thundereggs with ridges, usually showing strong flow bands on them.
Seems to be mostly geode-types lined with blue to purple agate, but does not know the ratio of solid agate to geode types.
