Thank you for posting this.
In looking at the two pictures, I notice an immediate difference involving the amount of dendrites in the Cosmos agate.
I also, in the Brian Head, I see more of a consistency (in this sampling) of the colors - the Reds and the blacks, whereas the Cosmos seems to have more of a dispersal of color.
Though similar - your description of location and seeing the material side by side seems to indicate that they should be treated as different - though related by proximity.

Lowell and Don: Boy that is a tough one I've never had the Cosmo or hunted the Cosmo agate location but I've had a whole bunch of Brian Head stuff mostly from an old Utah collector and he said his came from high altitude by the Brian Head ski area, and it is so variable that it mirrors the patterns in most every example of Cosmo you've shown. What I had left before my move was mostly tumble stuff so I didn't move much to Texas ( did you get the pile from my yard Lowell, or did someone else? *L*). I do know a lot I had was extremely dendritic, much was mossy or brecciated or cloudy etc and in every shade of reds, yellows, oranges with black etc etc. I don't see any reason why they can't be listed under separate identifications if the spots are widely separated. Definitely very very similar stuff though. ( Funny but Brian's -beefjello's Anderson Mine stuff is almost a dead ringer for some of the Utah stuff too)....Mel

Mel, I got quite a pile from your backyard. Some went to the club (there was so much I grabbed when you moved, I needed to send some elsewhere). Don, Here are some pieces from that pile: I'll look at those buckets again tomorrow to see if I have any others that show much difference from what I just posted. Don't know if this helps. ---Oh - Don - if you have shots of material from other collecting sites in that area - especially the ones you've just mentioned - can you post them here so I can see other differences between locations. Much appreciated. Utah is a place I have a lot to learn about. Much thanks, Lowell

Lowell: Far as I'm concerned, for location vs variety information for the index, I'd always give the nod to the collector with the local info and knowledge. Since Don has collected the areas recently and my Utah stuff was either self collected or bought form that old collector many years ago, I'm sure he has the best knowledge of the area and what is to found therein.....Mel
