Female Muscle : In peril

Entry for this month's theme of

Rhyna has climbed this cliff to investigate if she could uncover some animals to bring back her tribe.
Winter is always harsh in the Amazon Mountains, but this year has reached record low temperatures previously untold of, even from the old Ones's toothless mouths.
Since all the male youngs had already been put to death and eaten, and all the game hunted down to the minimal sustainable number, the strongest have scattered, on a mission to bring more food.
If they don't succeed, they would come back to offer their own flesh to the young trainees.

But Rhyna didn't find anything but trouble in this cave : as she was going back to the entrance, she bumped into some rock that apparently maintained the structure in place.

A big rock fell from the top, and Rhyna could onlyuse it as protection from the other rocks falling. The added weight is building up, she doesn't know how long she can hold like this.

She's thinking of trying to jump out. Will she have enough strength and speed to do it before she's crushed ?
