There is also a wide variety of rock types and colors in Lake Michigan. Photos 3&4 are of rocks from SW Michigan shoreline. Photo 5 is from the final stretch from Milwaukee to Chicago. One even looks like a fossilized tooth (photo 6).
The final handful are not natural stones at all. This is cast-off slag (the impurities separated out during the refining process) from a steel mill that has been tumbled by the lake for decades.
Around the city of Leland, Michigan, these are called 'Leland Blues.' Local artisans there make earrings and other crafts using these intriguing 'stones.'
The colors of tumbled slag range from turquoise to milky blue and all shades in between.
Cool stones. I'd heard about, but never seen, petosky stones. Ann Welch wrote a story in which they figure, which was my introduction to them. Sounds like you had yourself quite an adventure. Looking forward to reading about it eventually.
