Have a look at KMS's nice site of Greenlandic maps ( www.kms.dk ,
choose "Find et sted", then "Find et sted i Grønland"). The
quadripoint is there all right.
But have a look at the municipality of Qaqortoq: it consists of two
parts, the bigger part with the municipal centre and some other
settlements, the smaller with the settlement Qassimiut. The
municipality is cut in two by Narsaq municipality. This is also
described on the site of Qaqortoq municipality (
http://www.qaqortoq.gl/english/historie.html ).
Apart from that, I think all those q's are also great.
