I've loved geology since I was a child. My dad and I would collect rocks and he would teach me about them. I love your clips about geology so much that I've started my own geology folder to store many of your clips. Thanks for the great clips.

Willhelm, thank you for the message and your interest to what I collect in Clipmarks. Geology is really a challenging science. Plus a hobby, and a lifestyle for me.
If not Geology, I would have never found my way to America, which was not easy to come true.
