Mount Waterdeep

Trying to follow the elevation lines on the waterdeep map is giving me a headache. I dont think this was ever intended to be a proper elevation chart. Anyway, going to follow what I can, and make up the rest. Ultimately, it appears that Waterdeep mountain is going to top off in something like a spike 9" tall. Not terribly sure how I am going to pull this off yet but I have a few ideas.

Here are a few pictures of how this is going forward. Just getting the main structure cut and fitted.
