Aerospace engineer and meteor scientist Rob Matson has taken a first crack at an estimated strewnfield for the Lorton meteorite. Since no video of the event has yet been released, Rob used multiple witness reports, radar data, the hammer stone location and wind speed information to plot the possible locations for other meteorites from this fall. Rob has stressed the importance of searching within a 1 mile radius of the Dr’s office first but has provided this additional information should those search areas become exhausted. One should not interpret these coordinates in an x-marks-the-spot type of way. They should serve more as a general guide to areas where different sized stones would be if they existed. The strategy Rob suggested was drawing a line between the dots and covering those areas, but only after exhausting the areas around the Dr’s office.
Here is a map of the coordinates plotted in Google Earth.
Here is a copy of the Google Earth KMZ file for the Lorton Meteorite Estimated Strewnfield. You will need Google Earth installed on your computer in order to view this file.
Here are the raw data coordinates for the various masses:
Mass Longitude Latitude Dist (mi) Bearing

It looks like one of the points is on the driving range of the Fort Belvoir Golf Course. That would be a nice easy place to search if you had access.
There have been no new discoveries reported.
If you are a local resident in the Lorton area you are encouraged to be on the lookout for meteorites. Should you find one, please record the exact location where it was found and contact me at mike.hankey [AT] gmail.com
