The slab picture best shows the pattern. The colors are similar to Biggs and Deschutes but not a good pattern match. I bought a chunk on ebay and was described as "Ruffas / Biggs Opal Silicate type material found Vantage WA." I found this on wikipedia: "Biggs jasper is found between two of the basalt lava flows that once covered the U.S. states of Oregon, Washington and parts of Idaho."

Rufus is the next town upstream from Biggs, there is a couple deposits across the river in Washington also. Lots of similarities and differences in them all.

Lots of similarities and differences in them all. Yep. Rufus is the least silicified of the 3 - can have big, flowing hill patterns and soft blues on cream. I don't think stardiamond's piece looks like Rufus at all. The Biggs triangle goes from Biggs Junct. over to Rufus, then southwest to Wasco (the hamlet, not the county) with several deposits in addition to the original highway dig under US 97 south of Biggs (best known are Jolly Roger, Fulton Canyon, China Hollow, Beer's Mt.). If I had to make an educated guess based upon just the preform, I'd go for Fulton Canyon. As you said, there was some right across the Columbia from Biggs, but that wasn't dug for very long.

China Hollow was the best one to mine... The owner flat out will tell you no! No collecting anymore...

I suppose other than providing the collected location I could refer to it as from the Biggs family. The pattern looks like little puffy clouds. It is closer looking to Deschutes except that Deschutes has a swirling pattern. I got the piece for $17 delivered and it will produce 6 or 7 cabs. The biggest problem with the cabs is that they are dark and I don't know how much interest will be in the, because of that. I sold a Deschutes that was also dark but had the classic swirling pattern. Thanks, everyone for your help. I took a picture of the remaining slabs and had to use photoshop to adjust the exposure and color. It photographs bluer and lighter when photographed so I made the picture redder and darker. I have bad color vision so I could only make the picture look like the slabs.
