"I think this chunk is possibly about 18 inches in length and about 2 feet in diameter. My son has tried to take a sledge hammer to break it up, but he simply got some of the outer stuff off. Some spots look just like brown chert, and then some lighter browns with some lines do show up in other spots, so I feel there has to be something within that rock (hopefully, I have to justify having my husband help lift it into the back of the van!!)."

"It is browns. Looks like those nice creamy cocoa colors that first got me hooked, seems like some nice lines. I guess it could be about 500, I know this stuff is quite dense, so that might not surprise me. I had thought that if someone could bring a cordless drill with a masonary bit, make a few strategic holes, then take a chisel and hammer of some sort, and pop it off in chunks, may be the only way to handle something that big (besides, does anyone have a saw big enough to cut that one?). We were finding some small stuff with the blue, very pretty blue. Pictures on the internet I have seem of the blue Biggs was a sorry gray color, and so I did not think I liked it that much, but the blue we were finding was almost a sky blue with some brown lines, maybe not as much as the older stuff. We also noticed that some of the jasper were were seeing this time, although pretty in colors and lines, was rough and not as dense. Maybe a lesser stuff, not as well formed?"
