This one took way more time than I anticipated; It's difficult to try and capture something like an internal 3D environment without resorting to topography lines or relief shading. If I was going to do it over I'd probably add some "cutoff" lines to indicate intense slope, along with darkening some of the trail lines to give it more depth.
Also, while it seems pretty concentrated given the size of the Permian Basin Superorganism, it didn't make sense for there to be an even distribution of human development throughout the anatomy. Instead, "pockets" like this one are spread around major extraction/research sites within the park, connected by long stretches of tunnels.
