Nice pieces Geoff. Nice colors in the 1st, and I like the white squiggly line in that 2nd one.

Alaskan Thundereggs are something you don't see too often. Do you by chance have more you'd like to trade? I'm a die hard egg collector and trying to fill my collection from every location I can. Maybe flat rate for flat rate - I have lots of Oregon Thundereggs. In fact today I visited my mine and dug another 100lbs.... Colder than heck up there... Only 26 when I was digging lol

Wow! Those are the first Alaskan T-eggs I've ever seen. Those pale colors kind of remind me of the t-eggs from near Naches in Washington state. Very neat to have a member posting Alaskan stuff. Can't wait to see more from your region.....Mel

No strike out there. Beautiful stuff.
What classifies a stone as a thunder egg? I have some round rocks that are agate but I see that one of those is not round. I do not know if mine are thunder eggs or not. Jim

The white squiggle line is an interesting feature! .... What classifies a stone as a thunder egg? I have some round rocks that are agate but I see that one of those is not round. I do not know if mine are thunder eggs or not. Jim en.wikipedia.org/wiki/ThundereggI think rhyolite and a deformed star pattern are the main things.

Geoff - Sure thing on the eggs. I do like em around baseball size, but anything I can get my hands on is a fantastic achievment! Thanks much.
Jim - Thundereggs are typically volvanic in origin and are typically found in Rhyolite and Perlite flows. Most all Thundereggs are solid filled with agate, jasper, quartz and various forms of opal. One of my claims produces small thundereggs with precious opal cores. Often times we do find Thundereggs with a hollow center, however we call these Thundereggs with a "geode center". People commonly refer to Thundereggs as geodes, but most geodes are sedimentary in formation, but again not all. In Oregon we have lots of basalt. Some places contain a vesicular basalt with forms various agate and quartz nodules and often times these are hollow, so I guess we can consider these a geode as well.
Most Thundereggs are round in shape, however they vary greatly in shape - Some are round, flattened like a U.F.O. or even stretched out, what we call Torpedo's. It's very uncommon to see a smooth, round Thunderegg. Most all Thundereggs will be very warty on the exterior and have a raised ridge we call pressure ridges. These show where the agate has expanded to the outer edge of the matrix.
There's nice book called "Geodes" - Natures Treasures that explain things pretty good. One thing to watch out for is the Thundereggs the author used are not labeled correctly with the proper identification.

Hi! Great to see some more Alaskan thundereggs - these are such rare stones. Here's a few pics from my own collection, from the Talkeetna Mountains: There's a few more on my gallery (see my profile). For those interested in collecting some, i got these from Curvin Metzler at www.redundancydept.com/forsale.htm They were a bit more expensive than many of the US ones, but such interesting rare stones! I love them!

David - I see my emails came through. Glad you joined the group and thanks for sharing your Talkeetna Mt. Eggs. Still have not got one of those in my collection either. Had a fellow who lived in Alaska "supposed" to get me one lol, but that's as far as that went.
If any of the other group members would like to see more Thundereggs check out Eibonvales website. David has created a fantastic website dedicated to the worldwide locations of Thundereggs.

Wow that green matrix one is neat. Again, it reminds me of the green thunderegg matrix out of Naches, Washington except there the t-eggs are small and in aggregations throughout the matrix....Mel
