Lake Superior Agate
Rock-collecting on the shores of Lake Superior is a fun activity (even more fun if you actually find "something"). All of the smoothed beach stones are very attractive when wet, but agates like the one in the picture are a special "prize" for the observant rockhound.
This is a Lake Superior Agate, the "State Gemstone" of Minnesota. In the U.S., it is found on the shores of Lake Superior (Minnesota, Wisconsin and my home state of Michigan.). The colors distinguish it from agates found in other locations. Iron oxides give Lake Superior Agate rich tones of red, orange, yellow and red-brown.
Note:
This small specimen, measuring 1.25 x 1.25 x 0.62inches (3.2 x 3.2 x 1.6cm) was found by my Flickr friend Kevin ("Lakerdog"), I confess I could not find one on my recent trip to the U.P. Many thanks Kevin, for your expertise and generosity..
