sgarecfinders | Atlantis cut off from Earth

I'm maintaining a thematic list of stories with Atlantis cut off from Earth, either involuntary or by secession, or in which the expedition settles as a colony in Pegasus, i.e. all stories in which the Atlantis expedition has to fend for itself in the Pegasus galaxy, but I haven't added any recently. I've been thinking that this probably is due to me not scanning for them enough, so that I just haven't come across them at the same rate as I used to.

It's been over six months since I searched here last, so I wanted to ask whether you know of any other stories that would fit, but that aren't already on my list: http://ratcreature.net/fannish_stuff/sga_thematiclist_atlantiscutoff.php
