Yesterday the USGS GNIS data base was unavailable. Today it's back and now displays latitude and longitude in ddmmss format rather than decimals of a degree

I had a look at the USGS GNIS database. I note that the database is for The United States And Its Territories. Does the US claim the South Shetland Islands? Under the 1959 Antarctic Treaty no claims of sovereignty are recognised including those of Britain, Chile and Argentina.
Out of interest I searched for Howland island and Mystic Seaport and can confirm that both these places exist (-; A minor deficiency in the web site for someone outside the US is that there is no "All" option in the state list, making necessary to guess which state a location is in. Howland was obviously a Minor Outlying Island and Mystic Seaport had to be in a state near a coast so that narrowed down the search.
