This is Throwback Thursday #17.  In these, we look back into the past at ESCONI specifically and Earth Science in general.  If you have any contributions, (science, pictures, stories, etc …), please send them to esconi.info@gmail.com.  Thanks!

Here are some ESCONI patches and logos through the years.  The first few date to the 1960s.

This one dates to the 1980s and was sent by John Liskey.  Dave Liskey is his father and was the Junior Study Group Leader in the 1980s.

Found in the warehouse.  Most likely pre-1980.

Irene Broede’s trilobite pin!

I think that is the trilobite that Rob Sula created… 1990s or 2000s?

Messenger bags… again Rob Sula’s trilobite

Hats from the 2010s.  Care of Keith Robitschek
