Do you know where the first one came from?

Do you know where the first one came from? Good question. It looks like silver to me.

ashleeannajones - Not sure about the first ones...they're a cool find though!! I'm a little north-east of you up here in South Dakota. I frequently find pieces of (what I believe is) Jasper with those white "fortification" pockets in them like those last ones.

Thanks for posting! Makes us all think. Silver is my guess. Why is the west so different from the east? Because we were grazed by a comet 100 million years ago! That gave us many unusual minerals. Geologists don't know this because they don't understand comets. Comets do not explode on contact. Think "dirty water Balloon". That built the Rocky mountains as it raced from the Beaufort sea to Mexico and then submerged them under the Western inter mountain Seaway for 40 million years, until the asteroid hit the Yucatan and liberated it Creating the greatest Magic trick of all time.

Try to scratch the pyrite/silver with a knife or something. Native silver is pretty soft and will be easily scratched, pyrite is harder and brittle and will crumble/flake off instead.
By looking at the first few pictures I'd guess it would be a sulfide like pyrite or galena (lead sulfide). When soft metals like gold/silver are cut on a saw they "smear" from their softness, while pyrite/sulfides will break apart and cause pitting like the pictures seem to show.

Imagine A wall of water 5 or more miles high under a 500 mile diameter Comet racing Southeast across Utah carving and washing away rocks through Monument Valley and down the Grand Canyon.
