The Cliff Bed, located in Malheur County, Oregon, is a rugged thunderegg site known for producing nodules with striking agate interiors and dramatic matrix contrasts. Eggs from this bed often contain translucent to semi-translucent agate in shades of gray, blue, and white, sometimes accented with moss or sagenite inclusions. The rhyolite matrix tends to be coarse and reddish-brown, with nodules typically forming along exposed cliffs or steep slopes—hence the name. Collectors value Cliff Bed material for its bold internal patterns and strong visual presence when cut, making it a sought-after choice for both display and lapidary work.
