A very recent visit to Narsarsuaq with a following boattrip through the fjord proved that the wreck has disappeared with no trace left.
The history of it - at least according to the sign at Narsarsuaq Museum - tells that the ship was built in 1939 as the S/S "Hertha Maersk" of 1890 BRT. Impressed into US service, it was renamed the S/S "Montrose" transporting cryolite from the mine in Ivigtut, Greenland, to the US. It ran aground in the fjord on July 6th 1942.
Nobody I asked could tell when it disappeared. My own guess is that it was probably moved by the ice ans eventually quietly slid down the side of the reef.
I hope this cleared up the story?
Right now, the runway is very short due to repairs being made, but normally GLA (Air Greenland) runs a service a couple of times weekly with a B.757-200 all round the year, so it's not down to just Dash-7 and the odd ferry-flight...
I recollect a diversion in early 1970 when a BE80 called at night asking for diversion due to fuel. The night was crystal-clear and he was overhead with lights in sight. After the necessary half hour to put out goose-necks on the runway, I told him to start his descent - keeping the runway in sight at all times - and he made an uneventful landing, just to be frightened discovering the mountains the next morning!!! It is not a joke, but the facts" His only map was a Jeppesen chart (about A4 size) covering the whole of the North Atlantic and only showing coastlines, so he thought the terrain was flat!
MSA to the SW is 7000 and to the NE 11000 FT!
