Is this a repeated pattern when you are at the cabin, or did it just happen this time? If it's just this time, I woudl have a vet see her-major changes in behaviour can indicate pain or illness. Bladder infections are a common cause of behavioural changes.
If she is not used to being crated, you might have to do crate training with her. Has she been to the cabin before? What is she like at other people's houses? Are there mice or bugs at the cabin that might be driving her crazy?
Things like Rescue Remedy or something else might help ease her anxiety, but definitely look deeper and see if there is something else going on.
