Well, since I was searching for several hours despite the tips I've read, I add my own, standing right in front of Wilkes' Base. The koordinates shown on my minimap are X: -278 Y: 761 Z: 443 All the Dune Sea comments are confusing me because I never left Jundland to get here. The entrance is in Jundland - Southern Chasm, right south and a little bit west of Mos Anek, exactly west of Outpost Varath near the left corner of the Jundland map. I had to go through the PVP Area to reach it without going through Mos Anek. Oh, when you start from Outpost Salara, go first a little south, turn west to get up there (don't follow the valley to Dune Sea!), then follow the trail north west until you reach the PVP Area (all the flags are clearly visible), then cross the PVP Area to the south, get past Zaroshe and all the way down south on the map. Hope this post will help.
