The Hole in the Forest

Royal Explorer's Journal, travel day 37 of the third month of travel.

We are taking measurements of the large chasm adjacent to the village, the inhabitants swear that it already existed when they started building the first houses; I want to believe them even if I have doubts about their honesty. The walls show clear signs of excavation and also appear to be recent.

However, I wonder where all the removed earth and rocks are, furthermore there seems to be an opening under the surface of the water, I continue to investigate.
