I have gotten into it in the past few years, and been into gold panning for quite a while.
The wife and I head up to red top mtn. east of the mountains, found a few nice pieces of agate and chalcedony, and supposedly there are grapefruit size geodes on the tree'd side of the hill. Last year I found a nice hunk of Ellensburg blue with geode crystals. My favorite piece. There is a place called the rockin' tomahawk ranch out there where many people search, and many find squat.
Lately I've been heading up to greenwater though, and finding black and red agates in the old highway 70 landslide area. (then I go shooting!) Got a few fist sized pieces, and even a piece of botryoidal chalcedony. It's a bubbly textured piece. It's an easy 1 mile walk up there, but my last two trips, a buddy helped me haul out two 70 pound agate boulders! I sweat my ass off getting those back!
And now that the rain has come, I wait until spring to rockhound. I like it, but not freezing my butt off for it.
I did hear there is a spot on the carbon river that has petrified wood too, I'll have to ask my buddy where.
