After study this cut (SU568) is interpreted as relating to the construction of a hut. It is aligned with SU530 and SU615 and this set of features can be interpreted as the foundation trench and settings for upright posts that would form a hut or another small structure.

Square cut in the bedrock (posthole?) with the N and S sides partially eroded and the E side completely eroded - pickmarks on the E preserve the rough dimensions of the bottom of the cut. Aligned with two other cuts to the W (SU566 and SU567) and very likely related to them functionally (the space between each is ca. 35cm). The arrangement of three square cuts in a line is very similar to the three square cuts SW of here (SU533, SU547, SU549) and the dimensions (length and width) of all six are also similar. Spaces between SU566, SU567, SU568 is ca. 35cm; spaces between SU533, SU547, SU549 is ca. 45cm.
