FJD WYO 9. Museum specimen, old-time surface collected Eden Valley hardwood. Rare full round log from the Blue Forest/Eden Valley area near Farson. It’s a hardwood with prominent rays. It looks like a piece of wood, but it’s a rock. It retains lichen. This is one of those scarce specimens that’s great from any perspective – no bad angles. No glue or filler. The polished face offers a window into the interesting world of wood structures. Great example of Eden Valley, Wyoming, wood.  5 by 5 cm mirror-polished face; 7 cm tall; twelve ounces.  $150

FJD WYO 8. Museum specimen Blue Forest, WYO.  Rare full round log from the Blue Forest area near Farson. It’s a hardwood typically noted as pepperwood. This one has a lot going for it: note how much of it is coated with a thick natural shimmering and botryoidal blue chalcedony layer. It was a surface-collected piece that had been exposed to the elements for many moons, resulting is a gnarly, beautiful, interesting piece fit for any museum. Although the polished end is attractive in its own right, the exterior offers stiff competition insofar as interest goes – you can look inside at the botryoidal chalcedony that coats internal structures. It is cut and polished on one end and just polished on the other end, which I did to knock down some sharp points. 16 cm long; polished face measures 5.5 by 5.5 cm; two pounds and three ounces.  $300

FJD WYO 7. Dubois Limb Cast museum specimen. This is a specimen round fossil tree section. It has one natural end and one that is cut and dome polished. From an old collection and collected most likely before 1970. Nice external character and a lovely agate face.  53 by 38 mm mirror-polished face; 17 cm long; one pound and fourteen ounces.  No glue – No fillers. As solid as the Rock of Gibraltar. $75 

Note: since I did not personally collect this, I based the ID on experience – it’s possible this came from north of the Wyoming border in Montana - it’s the same general geologic formation and the fossil woods can be indistinguishable. Dubois is a type as well as a location, in my opinion.

WYO 27. Eden Valley museum specimen. Surface-collected full round Tertiary hardwood with a woody-appearing exterior. The polished face is beautifully preserved in black and brown with accents of blue chalcedony. Well-preserved cell structures. It appears to have been squashed a bit somewhere on the way to fossilization. Evidence of borers. No glue – No fillers. 9 cm long with a mirror-polished face of 6.5 by 11 cm; two pounds and seven ounces.   $85

FJD WYO 3. Big Sandy museum specimen. I’ve seen tons of wood from Wyoming, enough to know that this is rare material. The label on the back reads: “RARE WOOD ... Schilderia wood, Big Sandy, Wyoming (from Leroy Gearing Collection)”. I trust the source for the location, however this is not Schilderia. This is old time stuff. Found more than 50 years ago. I’ve seen other old-timer collectors call it shea oak or casuarina. I don’t know what it is other than that it’s a hardwood with characteristics of tropical wood. This is in excellent condition and is nice and thick like they made them in the old days. 3 cm thick! 11 by 13 cm mirror-polished face; one pound and fourteen ounces. $100

FJD WYO 4. Eden Valley museum specimen. This is an especially nice example of the wood from Eden Valley. Full round branch end of black beautifully preserved pepperwood, surface-collected, wind-blown with attractive patina, and undeniable evidence of borers that once tunneled beneath the bark.

No glue – No fillers. 9 cm long; 5 by 6 cm mirror-polished face; one pound.   $65

FJD WYO 5. Eden Valley museum specimen. Full round surface-collected forked branch, wind-blown with attractive patina. Nice cabinet size. Beautifully balanced, alluring. You will handle it and caress it. No glue – No fillers. 9 cm long; 5 by 6 cm mirror-polished face; one pound.   $85

WYO 29. Eden Valley museum specimen. 100% au natural. I got this from the collection of a rockhounding couple who collected all over the West starting in the 1940s. Back then the wood bearing areas of Wyoming had not been hunted and they found some great specimens like this one. It is a surface-collected piece with patina and wind sculpting. Nice eye appeal and knots. No glue – No fillers. 10 cm long by 6 by 5 cm; ten ounces.   $65

WYO 30. Large Eden Valley museum specimen. 100% au natural. I got this from the collection of a rockhounding couple who collected all over the West starting in the 1940s. Back then the wood bearing areas of Wyoming had not been hunted and they found some great specimens like this one. It is a surface-collected piece with patina and wind sculpting. Obvious growth rings on the end. No glue – No fillers. 22 cm long by 8 by 5 cm; two pounds and three ounces.   $75

FJD WYO 10. Museum specimen Blue Forest, WYO.  Rare full round hardwood log from the Blue Forest area near Farson. This baby is cut and polished on both ends and has the pleasing shape of a can of soup. A thick layer of blue agate all around, as well as blue agate within as seen on the ends. Overall a special Blue Forest specimen.  8 cm tall; polished faces measure 9 by 7 cm; two pounds and four ounces.  $175

FJD WYO 11. Museum specimen Blue Forest, WYO.  Rare full round log from the Blue Forest area near Farson. This is why they call it Blue Forest. All natural but for the one cut and polished end. It appears to have been partially exposed for many years prior to its discovery by a happy rockhound. The face is remarkably pristine. As frequently occurred in this location, the tree experienced substantial drying prior to petrification – note how the rarely preserved cambium separated from the heartwood. The exposed blue chalcedony is smooth and pleasant to the touch. Excellent cellular preservation. No filler/No Glue.  10 cm long; polished face measures 52 by 75 mm; one pound and six ounces.  $85
