Still on South Maroon?

I receive this text at 4:00am:
Hi. Stefan and I on south ridge of south maroon. My leg is so bad can barely move. Can you reach James.

I have tried to reach both, but have not heard back.  No SOS has been called, but I don’t know what is going on as the tracker seems to have stalled on the ridge.  Either it is having issues again, or he is just sitting there.
