Sweetwater Dendritic Agate; Sweetwater River region near Jeffery City, WY. Youngite: Near Glenwood Reservoir, Guernsey, WY Rough: Very druzy Slab: Petrified wood with stromatolites: Delaney's Rim area near Wamsutter, WY Turritella Agate: Delaney's Rim region, Wamsutter, WY I have a bunch of this rough and slabbed so I can take more pics later.

Here's one more. Pretty scarce stuff these days. I know it's from Wyoming but it's only found in old collections and I understand the location died with the finder. Also heard a lot of different stories about how the material got it's name. Stefoinite: Wyoming

Here are a couple more. I'm appalled at how much stuff I've built up over the years and since the move, I keep stumbling onto stuff I'd forgotten I had. *L* Medicine Bow Dendritic Agate: Location: a manganese mining district just north of Medicine Bow Wyoming. The black plumes in white agate often tend to be somewhat soft and dusty. Turritella Agate slabs: Delaney's Rim area, Wamsutter, WY

It's so depressing. I don't have much from this region - mostly what others have posted but theirs are better specimens. All I have worth this index is a rough piece of Sweetwater.
