“...Yakutia is bigger than Alaska and Texas combined. Rich in coal, diamonds, frozen wooly mammoths and other minerals and precious metals. Yakutia is rich with many agate areas too. These thundereggs are found near Mustakh-Yarjakh river.These agate have large bubbly like extrusions poppong out of the skin. Probably evidence of the volcanic boiling mud that created the opportunity for these agates to form.These agates were mined by the USSR for stone industy use. And brought out of the rugged Yakutia wilderness with helicopters in the 1980's. Some eggs weigh over 1200 lbs ! ..”
