I've made a few tunnel openings along the way as well to hopefully provide ocean access to anyone how wants to settle nearby as well.
1. Opening (work in progress not all that pretty yet)
2. Tunnel access point (Area where I dug a small bond and open area since from what was once very dense fir tree forest)
Don't mind help (good mining skill preferred to dig straight) and since this is a big project I'll try to make it easy for others to continue if I run out of steam from time to time. Don't have vein breaker and I am follower of Fo so just going around veins for now.
Oh and Silent lake is already connected to the boat tunnel in the south, I've just not yet had the time to put cat-eyes on it.
The tunnel Tekada mentions is now complete and access from North Liberty to the southern lake will be available once Vipsu breaks through with his tunnel. Cheers to all who helped, Tekada, Taka, Bern, Zuell. Now players travelling to Ivan's Folly rift events have an alternative.
