Sorry to ask, but I can't remember what its called nor can I find it ... so if any one here knows what I'm talking about I'd appreciate it

The mod changed the landscape of Solstheim, it came in 3 esp's ... one added a cliff and waterfall just south of the main quest village (Skaal?) ... the second increased the amount of trees, creating a forest in one area ... and I believe the third created a sort of palisade around Thirsk.

Does anyone know which mod this is?

BAM!
