Mystery Rock #6

Back in December, Diego emailed me pictures of an interesting looking, rounded rock that has some lighter markings on it that look like pictures. Diego wrote: Hello Evelyn, My name is Diego, and since you like to study rocks, I do have one for you! I was told it was sediment that created the pictures on the rock. Is it possible?

Mystery Rock #5

I haven’t posted a mystery rock in awhile, and I have some catching up to do! A little over a month ago I received an email from Liz, who is a Middle School teacher in the Boston area. Liz wrote, Once you have a moment and are not too busy with post-wedding stuff, could you take a look at the rock pics I have attached? The 8th grader I work …

For awhile I’ve been meaning to post Mystery Rock #3. A couple of months …

Mystery Rock #2

Earlier this month I posted pictures of a mystery rock that were sent to me by one of my blog readers. On Friday I received an email from someone who had been directed to my blog from the Skeptics Guide to the Universe Forum.

Mystery Rock

Mystery Rock, Photo 1. A few weeks ago a blog reader named Bob wrote me to ask if I could help identify a “mystery rock” in his backyard. Bob sent me several photos of the rock and wrote: Hi Evelyn, I’m reasonably sure I’m wasting your valuable time with these “silly”rock pictures, but I’ve been searching the web for similar pictures ordescriptions with no real satisfaction. I am a computer …
