We also see that she's placed down a recharge pod, some other gear and what I think could be some kind of handhold/rock-climbing thingamajig hammered into the wall:
So it is logical to assume that they entered through there and set up a mini-camp rather than entering via the main shaft, super-jumping to the top of the room and then planting all their stuff there.
