	What is a Thunderegg ? Thundereggs are spherical masses of rock that range in size from less than an inch to four feet in diameter . Most are about the size of a baseball . They have a knobby rind of drab , siliceous rock and a cavity filled with agate . From the out side they appear nondescript , but when sawed open and polished they may reveal the most exquisite and colorful designs ranging from five-pointed stars to miniature gardens .
	History of The Name : The Warm Springs Indians have been given credit for "long ago" originating the name . As the legend goes, ". . . the two adjacent snow capped peaks - - Mt. Hood and Mt. Jefferson - - would at times become angry with one another . During these disputes, accompanied with thunder, Mt. hood and Mt. Jefferson would hurl these spherical masses of rock at each other . Stray shots would land over in the Indian reservation, hence the Indian name of ' thunder eggs '."
	Origin of Thundereggs : Thundereggs are only found in areas of previous volcanic activity . As silicic lavas poured out on the ground, the gasses made it frothy and bubbly . The lava cooled and over a period of millions of years, became buried . Water, which contains many minerals including silica, penetrated the gas pockets through a crack in the nodule. As water slowly dissipated, the solution deposited agate ( chalcedong SiO2 )
