The elusive Hell’s Canyon Petrified Wood has been one of the most popular petrified woods for decades. It was once collected along the Snake River, bordering Oregon and Idaho, until the Hell’s Canyon Dam construction. Now the entire collection site is underwater.

This was a unique find, and there has yet to be another like it since. Hell’s Canyon Petrified Wood is known to be from the Cretaceous and Miocene era (25 to 145 million years ago). It displays beautiful wavy patterns, known as herringbone, which was the natural growth rings of the ancient Sequoia trees. It also contains dry rot holes that have since been filled with silica and micro drusy cavities.

NIPOMO MARCASITE

Many of the digging locations for this marcasite are on private property. It was allowed at one point to collect with the owner's permission, but a few rockhounds ruined it for the rest by trespassing, trampling newly-grown crops, and opening and closing gates not allowing cattle to get to their water sources. As a result, this material hasn’t been dug for a few decades.”
