Racetrack Siim

Sandatlas is written by Siim Sepp. I am a geologist (MSc) and nature photographer from Estonia. In this blog I will share stories collected during my trips to geologically interesting places. I also attempt to educate by explaining geological concepts with the help of my photos. I mostly focus on materials our home planet is made of (rocks, minerals, and sand). I live in Estonia with my wife and children. I work at the University of Tartu.

If you like my stories and photos, you can easily follow me via RSS or e-mail. I also have a Facebook page and Twitter account (@sandatlas).

You may use my photos for educational purposes or for non-commercial projects without asking me but attribution is required: Siim Sepp (www.sandatlas.org). Please make the link (to the page from where the photo was taken) clickable if you use my photos on the Internet. However, only non-commercial use is free. I do expect you to pay me if your intended use is for profit. Just contact me for further details.

If you prefer to purchase my photos from an established photo agency, take a look on Alamy. There is a small but growing selection of my photos.
