Situated along the "Sugar Bowl" strike which the thunderegg-enriched perlite flow occurred in lens (pockets) and the Black Queen pocket is the latest "Sugar Bowl" pocket found. Discovered by his mining partners (including myself), the claim was placed in name of Paul "GeodeKid" Colburn and several mining attempts were made but it turned out that like the original Sugar Bowl mine, the pocket is not big enough for commerical mining efforts. So it had been reclaimed.... a high percentage of the thundereggs is containing white bladed calcite inclusions in geometric patterns and psilomelane (manganese) inclusions.
