There is a game options setting that when being disabled does not show the compass mark. Cannot remember which one it was. And there was also a bug but I think that it got solved. https://forums.daybreakgames.com/eq...doesnt-show-instanced-zone-directions.266606/ The entrance to Deepest Guk is always the fallen tree in the NW part of the zone.
Deepest Guk has two possible entrances. You need to read the adventure window to find out which you need to go to. It can either be through a rotting tree trunk in Innothule Swamp or a barricaded door in Upper Guk. If it's the barricaded door, you won't see a mark on your compass until you enter Upper Guk.
