|The Olympic Range is well-known for weird volcanic rock. Outcrops like this were all over Tyler Peak (6,364 ft) on the northeast corner of the range. Though it doesn't show real well here, there was a distinct gray-green hue to the main constituent. Any ideas on the type of rock this is (a conglomerate of some sort)?
EDIT: my geologist friend Steve Nelson guesses it is "brecciated pillow basalt, intermixed with volcaniclastic siltstone and sandstone."
