While pruning elm that will be collected this winter, and collecting cacti my 7 yr old son and I picked up these stones. Please enjoy and offer opinions.
Thanks,

The last is the largest. About 18 inches across.

Hi Neil,

Several of the stones remind me of the kind of rock we found in the grasslands of North Dakota. It's tan jasper and is found in the Great Plains. Jasper has a tendency to chip or flake ... your first stone, is from what I can see, almost perfect! You also have a couple of nice plateau or step stones.

Where did you find your stones and did you share the fun with your 7 year old son? Children love rocks and can see shapes that you might never see.

Thanks for sharing!

Norma,

Yes.....My son loves collecting just about anything. Especially stones, cacti & even some bonsai. He's got a great imagination for seeing shapes in stones....and also a way of not seeing any limitations........... a few of the best stones he found & wanted to take home I could not carry out!

We live on the edge of Tulsa and found these just north about 20 miles on some Bureau of Land Management property that was extensively grazed for decades. As a result the winged elm have twiggy stunted growth with great trunks and aged bark. The area itself was strip mined and the bedrock exposed. Subsequently erosion and polishing has occurred (cattle, rain, wind, sun etc..). These Tan cobbles are to be found literally everywhere you look over a good number of acres & in the creek beds.

Upstream, the same type of stone can be found near coal operations. The run off has stained many of the stones black. I've not been there yet, but anticipate a trip in the next few weeks. Should be fun.
