I’ve developed a grudging respect for fluvial sediments… but Tertiary is too old to be really interesting. And I’m still pissed off that blackboard chalk is made of gypsum, and not really chalk. The world owes me one for that.
Where are you off to?

There are no good rock exposures in mississippi. Nothing “hard rock”. just a buncha boring old chalk and tertiary fluvial sediments. All the rocks here are Cretaceous and younger. none of which are well exposed.
Thankfully, I’ll be leaving this shithole forever in about 1 week.

It’s not a continuation of the Duluth complex, is it? So many maps have an unfortunate tendency to stop at the border.
We went to a nice gabbro-with-multiple-diking-events roadcut in Baja my sophomore year, grain size wasn’t so impressive though. I know there’s some entertaining stuff in Death Valley but haven’t ever visited it. I don’t even own a rock hammer, sadly enough.
Are there ANY good igneous outcrops in Mississippi?

Gabbro is one of my favorites. There’s a really awesome gabbro complex in Canada along the North SHore of Lake Superior that I remember going to in college.
Damn, right now I can’t remember where it is, or what its called…but to this day I can remember those HUGE awesome pyroxene’s. It was one of the first rocks I really Cracked with my new (at the time) rock hammer.
Quite honestly, I don’t think I’ve been to another gabbro since then…I just don’t live in the right area.

Friday Ark
Cats, Dogs, Spiders and ? every Friday. We’ll post links to sites that have Friday (plus or minus a few days) photos of their chosen animals as I see them (photoshops at our discretion and humans only in supporting roles). Leave a comment or trackback…
