A chance discovery among some photographs in the BGS Geomagnetic archive included this interesting image of a lighthouse. After much searching, this was identified as the Isla Observatorio at the southern tip of Argentina.
The following photograph is a good match for the fifth photo down on this history of the island, further evidence that this set of photographs is indeed the observatory on Isla Observatorio.
The Observatory was run by Lieutenant Commander Horacio Ballvé, who may be among the people pictured in the photo below.
Lastly are two photographs, one showing a small ship and the other a beach with southern sea lions.
