They only could excavate a small portion of the mountain because he said that the blocks deteriorate fast when exposed. I saw the portion the excavated. Very large formed blocks. That looked very much like what you’d see to build a pyramid. The other structures all looked like hills from a distance as well, but there are very much structures under all of that. The caverns under the town near that large pyramid mountain are very interesting with large monoliths which have inscriptions. I thought they looked like similar symbols you’d fine on runes.

I suggest anyone to visit this area. Also go and see the weird giant spheres in the forest. They’re not concrete yet don’t seem like meta either. They’re really interesting!
