On the morning of July 30, 2023, AGS hosted a field trip to investigate exfoliation popup “explosions” recently observed at Davidson Arabia Mountain Nature Preserve. Twenty-two attendees, including 17 AGS members along with Alan Cressler of USGS, Ranger Rick Kersey, park volunteer Darling Ngoh, and two park visitors, investigated a field of exfoliation structures of many shapes and scales, formed in connection with an explosive event around 12:15 pm on July 17. Read all about it in the August issue of the Atlanta Geological Society Newsletter available to all members. To join AGS click here.
