Was out trying to beat the heat and looking for new swimming holes to splash around in this past weekend with a old friend and decided to hit up the snoqualmie river in northbend. After some said cooling off I started to see some smaller jasper pebbles worth keeping for beads and eventually found a few cobbles worth keeping to try and cut. Heres my haul on a hot lazy day :-) hope your all staying cool out there!!

Ahh little chunks of heaven!  Be sure to post us the products you create from these beauties!

Nice pickins' there, Gergis!  I want to see what the second one looks like once you cut and polish it!

Unexpected from that river to be sure.

I had a feeling you were gonna say that frank. I assumed these were brought in by glacial movements and not from a nearby source although the sharpness of the bigger pieces made me think they wernt brought from very far.

Oh I also was at a spot just past the top of snoqualmie pass at lake kachess called box canyon that feeds the lake fresh cold glacial waters. Saw alot of blueish schist type stuff and some things that resembled variolites.. heres some of the rocks from there.

Kachess is interesting in that the Darrington -Devil's mountain fault zone has been forced east at that point. It extends in bits and pieces to the hills just south of the eastern most highway exit that is in Ellensburg. The offset is 156 kilometers . The same amount of offset exists on the other side of the fault but there it is the intersecting fault that is 156 kilometers north. The Straight creek fault drove the piece of the D-D Mt. fault south and east but up north it just goes north south. Schists from Marblemount are also found at Harrison lake B.C.  due to the fault off set.

I need to know what this one is, i find alot of them on my gold creek, i call them embedded hay from a hurricane rock

[Gergis]

I think its a type of porphory or chinese writing stone.

White feldspar crystals in diabase most likely, I think Gergis has it right.

[Gergis]

Quite alot of it in the creek but mostly smaller cobbles.

Rarely this happens to basalt but for the most part it happens in the lower part of the melt that provides the basalt and is only exposed when the bottom of the magma chamber is exposed by erosion. The diabases are extremely tough rocks so they last in the environment .
