Thundereggs from the Crane Creek area in Oregon are lesser-known but offer a unique mix of textures and colors, shaped by the region’s volcanic past. These nodules are typically medium-sized and feature agate interiors in shades of gray, tan, and occasionally soft reds or blues, often with subtle banding or mossy inclusions. The rhyolite matrix is generally rough and weathered, giving the eggs a rugged, high-desert look. While not as widely collected as those from more prominent beds, Crane Creek thundereggs are appreciated for their natural variety and their potential to reveal unexpected detail when cut.
