I went out picking rocks today with my 10 year old. We got about 50 pounds of cuttable rock. Here are a couple interesting ones. Anyone know what they are?   |

Don't know and maybe some type of jasper for the red one. That red one is nice. Find any more garnets when you were out?

Saskrock, I have had someone I.D. the red one as brecciated red jasper. I did find a large rock(about 10 pounds) with some red spots that may turn out to be garnet.
Dixie, I am half way across the country from you, Saskatchewan Canada.

That's one of the few states that I am not working in . If you do make it to South Dakota and I might head that way . Meanwhiles , if you have any for sale , shoot me a private message . I am compiling a batch of diverse and varied rock to send to china to have carved into animals so I am always looking to buy different types of rough rock .

GO TO THE BLACK HILLS IN SOUTH DAKOTA, collecting opportunities abound there. If you make it, be sure to start at the School of Mines museum in Rapid City. Assistant curator Kelly Clever can get you pointed in the right direction (assuming she's still there since I was there 3 years ago, of course). Also look for Dan Patch for pretty-decent schorl, Bob Ingersoll for tourmalines, and any of the other way-accessible pegmatite mines visible while driving around the Custer/Keystone area.
Also, try to get a copy of the old Roberts and Rapp publication, a great study of Black Hills mineralogy.

I think the brecciated material has some hematite which will polish up nice along side the red jasper it looks a little like maryellen jasper from Minnesota's iron range.

The one with the red in it looks close to some pigeon blood agate I have that came from Utah.

well comments five months later aren't too late are they? the first rounded brown is quite water rounded and polished, however there are sharply angled light areas that have a prismatic shape to them that suggests feldspar, if it is igneous in origin then you may have something like a pegmatite, however the crystals look a little small for that, if you have not identified it yet, you don't have to slap it, just knock a corner off with a hammer and cold chisel.
I would take the id of a breccia with jasper for the second.
You are very correct about the glaciers doing a job on all of the Canadian plains. I studied glacial geomorphology in upstate New York, where a whole pile of glacial features are found.

Well personally I'm still waiting for that switch to get fixed.
