If you have not discovered Dirtgazing already, here is a plug for the blog. One of my photos, which appear here from time to time is in this edition combined very sympathetically with photos from other bloggers. Get out your “dirty” pictures and send some along to Melinda, she appreciates submissions.

You are welcome. I am hoping some of my archaeologist friends will get the courage up to send along some nice pictures of old dirt.
