OAT Patagonia trip, Dec 2013.
Ushuaia- I took a little walk down from our hotel that is about a block away. Probable translation of the plaques:
"The city of Ushuaia in tribute to the civilizing action of the Argentina Navy. 4 October 1971"
"Symbology The sea, symbol of majesty and power, marks with the union of the Atlantic and Pacific oceans, the geographical location of Ushuaia. Between the waves, emerge the Republic. Guarded by three dolphins that represent the components NAVAL POWER (Ships, Marine Corps, and Naval Aviation) and symbolize fidelity and permanent custody of the LIBERTY of the COUNTRY.
December 13, 1971"
