- Ron Schott's sandy meme. Ron's got some nice photographs of sand from different places. His challenge was to tell him where it came from. I left a few guesses, but perhaps you have other thoughts.
- Callan's NOVA blog. Some Q&A with Michael Welland, the author of "Sand." Callan's students have asked some interesting questions about "sand."
- Clastic Detritus: anthropogenic forcing of fluvial systems. Brian has some cool pictures and discussion about human-induced changes in a big river system. Neat stuff.
- Michael Welland's Sandglass. Speaking of "sand," author Michael Welland wrote an entire book devoted to the subject. Being a clastically trained sedimentologist, sand is near and dear to my heart. I haven't read the book yet, but Clastic Detritus has a review and interview here and here.
Oh, and don't forget to cruise on over to the Hairy Museum of Natural History for some kewl links about fossils...
