It’s Amethyst, I know that. It may also be a geode, so crack it open and see what’s inside! It’ll look alot better on the inside.

DEBORAH, where do you live? I live in Northern California and I can tell you exactly where to go to find geodes in the wild for your son. They are everywhere at this site and I have shown people that do not have a smooth surface nor do they look like they are from this planet and yet there they are…

It’s conglomerate. It is not a thunderegg or geode as we have many where I live and they are very distinct. We have conglomerate from all over the u.s. and this looks like some of the conglomerate that we found in upper washington this past spring.

Deborah, I do not know all that much about the Alamogordo area. I’m not sure which crinoid you are talking about … maybe you can link to it? In terms of the ‘rock eggs’, my best guess w/out seeing them is they are some sort of concretion, but that’s only a guess!

Forgot to ask…..Do you know if there are any geodes in the area ? I’d love to show my son

one “in the wild”……Any area you think would be interesting to a nine year old ? We’d love to

hear about it……….. Thanks, Deborah

Brian,
So happy to find your site. I am a very amateur geologist. And I came from British Columbia, Canada to Alamogordo New Mexico. I am very interested in the Lake Valley Region, and my house is so full of rocks that myself and my son have collected it’s crazy. So many unusual things here. We have found many small fossils, and these odd round rocks that, when broken open have three or four layers of solid rocks that are distinctly colored. They all seem to have a solid central core. My son calls them ‘rock eggs’. Your site is wonderful, and very helpful to someone like me who has a deep interest and respect in the earth. We would like to see the crinoid fossil that you found, do you know how you got there ? Also, any idea what the rock eggs are ? I’ll try and post a pic.

A cannon ball that has been steeping in a chemical stew for a century or so?
