What are these colorful rocks?

[treasuresalvor]

For years I've wondered what these rocks were in this old outdoor fireplace. I've never seen any like them along this shoreline so I assume they were gathered somewhere else to build this. There was also an old large wall built with these in it but most of that has crumbled away.

Someone's rock collection. Lots of mineral collectors do this. A lot of it looks like mixed jaspers.

Very interesting. Thanks for sharing. Sorry I can’t help with the ID.

It's unique for sure. There are a lot of different types of rocks, some agates, and even the occasional gemstones found along these lake shores because of the glacial drop but I haven't seen anything like that anywhere.

It looks like banded iron. Gary

Rhyolite, probably "Wonderstone rhyolite". I'm guessing the location is Nevada/California?

I love cutting this stuff, makes really nice cabochons

It's actually in Iowa.

You're absolutely right! I just finished burnishing two three pound barrels today. We collected them over around Fallon, Nevada. Beautifu stuff! Love your cabochons!

Lovely and artistic fireplace. Hope it doesn't get destroyed for the rocks. I missed out getting to view an indoor fireplace made with Silver, Nickel and Cobalt rocks. The original home owner was a mine owner. There was a house tour last year that I missed by a few days.

Looks like agate, but I am no expert on geology

Someday it will probably be destroyed to redo the landscaping. It's a very steep bank and some of the wall that extends to the left of the fireplace had crumbled away and was removed this summer. I should have took some of the rocks that fell out this spring but I didn't.

The banded pieces definitely look like wonderstone I've collected in the West, Central desert of Utah
