The Chesapeake Bay impact crater and its impacts.
Research Geologist, Geology and Paleoclimate Science Center, United States Geological Survey, Reston, VA
About 35 million years ago, during late Eocene time, a 2-mile-wide asteroid or comet smashed into Earth in what is now the lower Chesapeake Bay in Virginia. The oceanic impact vaporized, melted, fractured, and (or) displaced the target rocks and sediments and sent billions of tons of water, sediments, and rocks into the air. Glassy particles of solidified melt rock rained down as far away as Texas and the Caribbean. Models suggest that even up to 50 miles away the velocity of the intensely hot air blast was greater than 1,500 miles per hour, and ground shaking was equivalent to an earthquake greater than magnitude 8.0 on the Richter scale. Large tsunamis affected most of the North Atlantic basin. The Chesapeake Bay impact structure is among the 20 largest known impact structures on Earth. Continued subsidence and sediment compaction within the structure has maintained a topographic low that has caused geologically recent and modern rivers to drain toward it, thereby controlling the location of the Chesapeake Bay to some extent. These observations point to the fact that this 35-million-year-old impact structure is still affecting us today.
Non-Smithsonian visitors will be escorted to the Q?rius theater at 6:45 and 6:55 p.m. Society members will host the speaker for dinner at the Elephant & Castle (1201 Pennsylvania Ave.) prior to the meeting. Members may meet at the restaurant or inside the Constitutional Ave. entrance of the NMNH at 5:00 and walk to the restaurant as a group.

Fairfax Urban Search and Rescue in Nepal.
The description will be: After the April earthquake in Nepal, the urban search and rescue team from the Fairfax County Fire and Rescue Department responded and rescued two victims from collapsed structures. The team is one of two search and rescue teams sponsored by the federal government to conduct international search and rescue.
John Morrison serves as a Planning Section Chief within the Urban Search and Rescue team, Virginia Task Force 1, which serves as one of the 28 domestic response teams under FEMA and as one of the two response teams under USAID/OFDA. The planning section is responsible for situational awareness, information technology, mapping, finance and documentation while the team is deployed. He has been a member of the team since 2003.
Meeting Room and Dining Arrangements: We meet in the glassed-in room at the back of the main dining room, The Fife and Drum. We order individually from the Club menu, which has a nice variety of dinner offerings. We pay a single bill, so we collect $25 from each member and $30 from each non-member. If a diner orders more than $20 in food and drink, he adds the amount over $20 to his contribution. The $5 overcharge goes to the Room Fee, Tax, Gratuity, and the Speaker’s Dinner. We collect on the Honor System. Reception is at 6:00 p.m. downstairs in the Old Guard Lounge. We order dinner at 7:00 p.m. The presentation is at 8:30 p.m. Please note that the meal orders will be taken at 7:00 p.m. Allow 15 minutes for security entering Ft. Myer as all civilian vehicles are searched. To ensure access to and from Fort Myer, use the Hatfield Gate, open 24 hours a day. Reservations are not necessary, however, we need a head count; so, if you wish to attend dinner, please inform Bob Fraser at 703-624-3965 or via email at email@example.com. If you wish, please feel free to attend the talk without dinner. Non-members and guests are welcome. Please send changes of address or email to firstname.lastname@example.org.
This 3 hour event specifically caters to Webelos Scouts – but is open to other youths, Girl Scouts, homeshoolers, etc.: 5th through 8th grade. Registration through the Boy Scout Council at http://www.ncacbsa.org/events/event_details.asp?id=699709&group=118988

The Role of Paleoecology in Everglades Restoration
Research Geologist /Project Chief, Eastern Geology and Paleoclimate Science Center, United States Geological Survey, Reston, VA
Restoration of the Florida Everglades is projected to take 30-50 years and the cost is currently estimated to be almost eight billion dollars. Success is contingent on restoring more natural hydrologic flow through the ecosystem and on understanding how the ecosystem will respond to projected climate and sea level changes over the next century. This talk will illustrate how paleoecologic data is guiding restoration efforts. Applied paleoecology is a reality!
Non-Smithsonian visitors will be escorted to the Cooper Room at 6:45 and 6:55 p.m. Society members will host the speaker for dinner at the Elephant & Castle (1201 Pennsylvania Ave.) prior to the meeting. Members may meet at the restaurant or inside the Constitutional Ave. entrance of the NMNH at 5:00 and walk to the restaurant as a group.
