It's in the Beorning section, but it's not Beorn's House. Is it Woodmen Town? I feel like I've read about it, with the tunnel, but I can't seem to place it.
(This is Beorn's House, in case anyone is wondering; it took me FOREVER to find, because it's in Tales, coincidentally on page 44).
My guess is a small, nameless Beorning settlement. It doesn't seem to fit anything else.
The other one looks like a nameless Woodman settlement. It's definitely not Rhosgabel, Woodland Hall, or Woodland Town (those are pictured Heart of the Wild 93 and 96).
I smashed down the light and dared Valinor
I smashed down the light, revenge will be mine
Morgoth is right - both unnamed dwellings of their respective peoples. If you have an hour so you don't want back there's a video of the creation of the Beorning's dwelling here: http://www.youtube.com/playlist?list=PL40E83D2190D4B7E7
