Video: ESCONI October 2020 General Meeting - October 9th, 2020 at 8:00 PM via Zoom - "The Blue Forest of Ancient Lake Gosiute” #fossils #paleontology #PetrifiedWood #chalcedony

 

At the October 2020 General Meeting, we had Mike Viney speak about the petrified wood of the Blue Forest in Wyoming.  The Zoom meeting video has been processed and is now available for viewing.  After the presentation, Mike sent a pdf with many of his slides (RBlueForestOfAncientLakeGosiute).

Mike is a Teacher in Residence at Colorado State University and a long-time collector and researcher into petrified wood. The title of his talk was "The Blue Forest of Ancient Lake Gosiute: Sweetwater County, Wyoming". The Blue Forest is a famous source of petrified wood known for its blue chalcedony. Lake Gosiute was one of the lakes in the Green River region during the Eocene.

Mazon Monday #26: Braceville Field Trip Report #fossils #MazonCreek

This is Mazon Monday post #26.  What's your favorite Mazon Creek fossil?  Tell us at email:esconi.info@gmail.com.

-----------------------------------------------------

The weather could not have been better for the annual Fall trip to Braceville, IL for Mazon Creek concretions this past weekend.  For both days, we had lows in the 50s and highs around 70 degrees.  There were 51 participants on Saturday and 42 on Sunday, with 9 of those on Sunday from the Kalamazoo Geological and Mineral Society (KGMS).  Thanks for joining us!

We had several donations of fossils.  Most notable was the donation from Ralph Jewell, Thanks!  He donated several buckets of concretions, Mississippian fossils, Ordovician fossils, Pliocene fossils, and some fossils from Morocco.  Hopefully, people won't be too confused with their findings!  Everyone went home with something... be it finds from the spoil pile or the donated fossils.

There is a great field trip report by Ralph Jewell on the Fossil Forum.  If you aren't a member over there, you are really missing out on some great information and discussions.  Sign up... it's free!  You will learn more than you ever imagined about fossils and their place in the natural world!

Here are a couple videos of the distribution of donated material on Saturday.

Sunday.

Here is a photo of the hill... it's shrunk since my first visit in 2004.

ESCONI Field Trip Report - Braceville Fall 2019, #fossils #MazonCreek

The Fall 2019 trip to Braceville was on September 14th and 15th this year.  The weather was great on Saturday, maybe a little hot for digging.   On Sunday, the day started out wet, with a steady down pour in early morning, but a few hardy souls went in right from the beginning!  It was two good days of fossil collecting, renewing old friendships, and making some new friends.  It may take a little while with the freeze/thaw preparation, but hopefully, we'll all come away with some awesome new fossils for our collections!

With all the rain we have had this year, the path got pretty overgrown this year.

There were some wet areas and they really turned to mud on Sunday.  Here is a little video summary of the trip.

We did the customary dump of fossils on both Saturday and Sunday.

 

There was a special visitor on Saturday...  A caterpillar from an Imperial Moth was found.

Here are various pictures from the 2 days of fossil fun!
