I had wondered about that.

From http://www.navcen.uscg.gov/Loran/ , I gather the CG are keeping
these transmitters working:

Canadian East Coast GRI 5930 (Caribou ME, Nantucket MA)
Canadian West Coast GRI 5990 (Shoal Cove AK, George WA)

and

Russian American GRI 5980 (Attu AK)


The CCG already seem to have expressed their opinion that LORAN wasn't
necessary for safefy (with GPS/DGPS having better resolutions). I would
be surprised if they would pickup the tab to keep it running.

The question will be how long before they make an announcement.

I've heard after Memorial Day through an attenuated grapevine, can't vouch
for accuracy but there it is.
