50 Years Ago – June 1971

• The June 1971 bulletin refers to someone who is a member as an “ESCONIan”. Now you know the proper term to use…
• The “Coming Events” section of the bulletin lists a “Gem and Mineral Fair” in Belvidere, IL. Anyone know which club put this on?
• The Western Springs and Downers Grove juniors groups took a field trip that included collecting fossils in black shale from Pit 14.
• ESCONIan Verne Knight presented a program to the Ozark Earth Science Club in Arkansas.
• The Archeology Study Group visited the Forest Home cemetery in Forest Park, which is built partially on a Native American burial site.
