The primary trap that youâll find with aluminum cans is a higher than normal premium on the product. With a $0.60 per pound market rate for general aluminum, the least you should receive for your cans is $0.30 per pound. Anything less than that is a scrap yard dealer attempting to maximize their profits at your expense.
Lake Superior agate. The Lake Superior agate is a type of agate stained by iron and found on the shores of Lake Superior. Its wide distribution and iron-rich bands of color reflect the gemstone's geologic history in Minnesota, Wisconsin, and Michigan. In 1969 the Lake Superior agate was designated by the Minnesota Legislature as the official state gemstone.
Rock hunters and agate collectors traveling around Lake Superior should consider taking a slight side trip (on Interstate 35) about 36 miles south of Duluth, Mn to see the very impressive Lake Superior Agate collection and rock displays at the interpretive center located with the Moose Lake Park Visitor Center.
