.	Dwarves' Earth Treasures Museum: Lake Superior Agates Minnoseta and Iowa	.

    Here be the famous "Lakers" a short name for Lake Superior Agates well known throughout the Midwest states especially Minnoseta, the source of best Lake Superior agates. They can be found in other states like Wisconsin, Michigan, Iowa, and some states along the Mississippian river. They were formed in a billion years old basaltic lava formations of Lake Superior (all the way to Kansas), and the actual age of agates themselves are not known since they can be formed any time after the solification of basalt lava beds. If they're that old, I would be quite amazed that they're still intact despite hundreds of millions years of weathering. Those agates are really lucky that they escaped the destructive tectonic forces of the active and everchanging Earth.
    Red, brown, gray, orange and white seem to be most common colors of the Lakers, but they can include other but more rare colors. Alternating bold red and white bands seems to be most desirable of any Lakers. They had been found in their basalt lava rocks, but most agates found in the Great Lakes states were removed from their host rocks and deposited by the ancient glaciers several tens of thousands years ago. So the agates were scattered all over the glacial deposits and along Lake Superior shorelines in Minnesota (most adundant), Wisconsin and Michigan, and some agates were carried to the south by the Mississippi river. Even so, good sized agates of good quality are hard to find.

	Small but very pretty!	Rare sagenite type

This is actual Laker Superior Agate from Cedar River, Iowa! The polish is so good that all of those annoying mirrorlike reflection can't be avoided no matter how I tried!	This is a Moss type of Lake Superior Agate from Minnesota. That showed how reddish moss minerals were formed before being covered by agates. I don't know how rare the moss agates are.

Really big Lake Superior Agate! It was polished by its previous owner
(it came with the big old collection I got from him). I think it's about 2 pounds (no scale on me).
