Went up the Clackamas with @pnw_rocktography, who knows how to find the zeolites. Found this fairly huge pocket of siderite on common opal with big old opal coated selenite clusters. We busted up the huge boulder to more manageable sizes and got a lot of good display material and learned quite a bit too! Hit a quite productive calcite vein later, and I'm sure you'll see photos of that material on his feed soon. Damn good day out there in the snow, and it's only 3! #rocks #crystal #crystals #minerals #zeolite #zeolites #siderite #selenite #commonopal #botryoidal #vug #pocket #mthoodnationalforest #clackamas #clackamascounty #clackamasriver #rock #basalt #rockhounding #oregon #geology #silica #rockhoundingoregon (at Mt Hood National Forest)
