Hi from your traveling bunny friend, Buster! We visited the A. E. Seaman Mineral Museum in Houghton, Michigan and saw a lot of cool rocks! Some were found locally in Michigan, and others were from around the world.
In the first photo, I am standing in front of some big quartz crystals. Quartz is the second most common mineral in the earth's crust. It is very hard. When it crystalizes (forms into crystals) they are often hexagonal because the molecules that make up quartz, silicon oxide, tend to stack on top of each other in hexagonal shapes.
In the second photo you see me in front of a geode. A geode is a round hole inside rock that is filled with minerals. In this case, it is filled with little quartz crystals. This geode was found in Keokuk, Iowa.
In the third photo I'm in front of some hematite that formed as a stalagmite in a cave. Water with dissolved iron in it dripped down into a cave. As the water evaporated, the iron oxide in it slowly grew into round globular shapes.
Just for fun, I am including photos of some other cool rocks from their collection.
In the Copper Pavilion just outside the museum is a piece of native copper that was found on the bottom of Lake Superior. It is the Guinness World Record holder for the largest boulder of copper!
Museum tickets are very inexpensive, and the museum is free for kids under 8.
Did you know? Little balls of hematite have been found on Mars!
