Possibly Vistaite Jasper Rough Chunk!

This is a chunk from an old estate sale.  This could be vistaite, as I've seen similar stuff come from that area, but I could be wrong.  

Vistaite is an old stock Oregon stone that was mined in the Ochoco Mountains of Oregon.  It was a highly popular stone back when it was actively mined, and after he got his fill, the original mine owner left the mine to the county as a public mine for all to access.  Sadly, the National Forest service decided this was not a good idea and spent tens of thousands of dollars to cover the public deposit with loads of dirt to make it undigable.  Still, every once in a rare while some small chips can be found, but any rough on the market is generally going to be old stock material, like what you see here.  It is a pretty hard stone, and takes a pretty decent polish.  It often has a blue green tint, and can somtimes have rolling hills pattern.  It is a pretty neat one to work with for sure!
