While not always true internationally, at least in the US most jurisdictions won't charge for rescue as long unless you weren't careless and reckless.

(Keep in mind that rescue in the wilderness can easily take 12-48 hours.)

That said, laws allowing the state to recoup rescue costs are becoming more common as satellite messengers have become more prevalent, leading to more non-emergency nuisance calls.
