Mako started moving further away from the shelter but still, he didn't have any luck finding an information tablet. He had been moving for a while and was a decent way away from where the shelter was so he decided to turn back and circle around back toward the shelter.
This way he could check the remaining perimeter for the tablet before arriving back at the shelter.
The structure of the mountain was such that it had uniform steepness all around for most of the way up, but coming close to the top, one side of the mountain started to become less steep and eventually flattened out, this was where the lake was situated and where the group had decided to build the shelter.
However, the other side of the mountain was significantly longer than the other. This long side appeared to be incredibly steep, with sharp cliffs and jagged rocks that tower higher than the other side of the mountain, reaching its true peak.
