WOW!!!!

Ok cool :)
You're most welcome, its a wonderfull blueprint!

I added a link to this screenshot from the item description so that other people could see your notes on temperatures and creatures. Thanks again!

You're welcome.
I think it has something to do with the fact that also in the main base i've had dust devils, though not as many as now in the biome...
I mean... having the canyons next to the base and all... ;)

That's cool that you are seeing a good variety of creatures. I haven't seen any of the Dustevils in my build, so I am glad that you are getting them! Thank you for the details!

Oh yeah, and these chizzards.. seen 2 of those so far.
Regular and arctic (each 1 time seen)

Other trees wont grow.. i tried... though might just change the surface block where i want to plant it....

On the 'upper circle level' its around 42°F at noon.. around 24-35'ish between 9pm and 10am...
Around 35° at noon on the roof - incl freezing debuff! :p

Rambou (everywhere, peekstone ^^)
Pigsies (day, night, feral)
Leavy (regular, mossy)
Dust devil (lots!)
Turg (lots!)
er.. adult Krab... (day, night)
Arctic Miru

I just placed some 'try grass' blocks at borders of sand/rocky and rocky/'exit'.
I want to get one of those mice with a fire-tail ;)

Fun fact:
During the 'pool' build, i had to remove like half the corrals i was using later for the roof.
I placed no shell or grass (but like 3 'blocks' of tallgrass/weeds) until i've seen that stuff grew by itself.

I see Rambeau and Feral Pigsy in that image. If I may ask, what is the air temperature, and what other creatures have you seen spawn at that elevation? (Also, that may affect your saplings - I remember reading that Elderwoods will grow in the cold, but the others will want it to be warmer.)

I do not believe Autumnwoods give saplings, just Ashenwood, Elderwood and Cragwood. So if you like the Autumnwoods, you will need to build them. But other trees would look nice there, too.

Oh yeah, hope you see the sapling there... i was lazy to build all the trees.. specialy as i had saplings for it :)
Still searching for autumwood saplings... 1800 leaves and none so far...
