New US State and a Super Rare Location – Avon Montana

Avon01It is an unusual event to introduce a new US state to the Eibonvale gallery these days, but here is a first egg from Montana – an Avon thunderegg, collected from the surface of a parcel of private land in Avon.  This is not to say that this is the only Location in Montana by any means – I am aware of a few others, most notably several beds in the Bitterroot area, but finding them will be a challenge!  For now, this is the first and only Montana thunderegg I have ever seen.

PS. The famous Montana Dryhead Agates, though very nodular, are not thundereggs.

Tidying Up Succor Creek and a Seascape

Succor Creek thunderegg – Seascape

Finally polishing a few new specimens from Succor Creek has given me the chance to tidy up the page a little, booting out several specimens and uploading a clutch more.  This is a location I have not paid a huge amount of attention to in the past, something I am starting to rethink after getting some new specimens.  Especially after encountering the seascape specimen above – which seems a very good representation of the stormy North Sea. Like killer Green, these eggs seem to stick to their formula quite reliably, so when something else comes along, it tends to stand out.  Here, for instance is a specimen with yellowish agate. Succorcreek06One thing that makes the Succor Creek stones into something exceptional is their snowflake dendrites, which are very common here and often provide that touch that makes an egg into something amazing.

Opal Butte and Turkey Tail


Opal Butte Turkey Tail Thunderegg

Opal Butte has been on the gallery for a while, stinking the place up with it’s rather muddled collection of stones – not a page that befitted such a grand location.  Now, as well as finally tidying it up a bit by adding my own specimen to the gallery, I have also added the sister location known as Turkey Tail, an absolute stunner of a location with an amazing matrix.  I look forward to exploring these more.

Rare Agareless Giant from Gold Basin, California

goldbasin04Not a new location, but this 23cm monster has been hanging around for a while awaiting polishing – and here it is.  This is an unusual Californian location that i have yet to see any agate in.  Instead the cores are complex blends of crystal and minerals of various kinds.  I also took some detail shots as the stone is so big and busy.  You can see the other smaller Gold Basin thundereggs here.
