Dodging the weather is tricky but we did have one day that was nice enough last week before several days of -20 to -30 lows that followed.....BRRRR!
I agree good eye on that Swizz, those pressure ridges (seams) you noticed are a dead give away on the T-eggs. The ridges form from the slow filling of the silca (quartz) material into the gas bubble of the rhyolite flow. Over a very long time the layers formed enough to swell the bubble beyond it's original size causing the pressure ridges to crack the shell of the bubble. First pic is on the saw for cutting, alignment is just about how Denise has it in the first pic above. Ironically enough the cut ended up right between the bubbles on the outside in that picture too. 
Another 30 minutes later or so here is what showed it's pretty face to the sun for the first time ever seen, we'll be looking for more of these soon to verify this might be a new thunder egg bed locality for Colorado too!  Nice contrasting colors/blend of banding and small plumes with a very solid form. Not to bad at all for a surface/aluvial find......enjoy.
