Lake Superior Agates

These are Lake Superior Agates found on Minnesota beaches. The agate on the left is one of my all-time favorites. It has three distinct regions: an iron-rich, red shell, characteristic of almost all Lakers; a large central region of clear crystal that looks almost like the meat in a citrus fruit; and a third region (on the left of the photo) of thin, parallel layers of the clear crystaline material. The agate on the right reminds me of a piece of Christmas candy.

Here are some more Lake Superior Agates. You can see that while they are similar, each is quite distinct. This broad range of features is why I really like to tumble polish agates. You will see more in the School of Hard Rocks.
