safety is a personal responsibility - rescues in natural environments are expensive and complex, and can take days and cause a lot of damage to the environment, therefore it is good to avoid risking this when it is not necessary.

it is advisable to calculate the total time that will be spent traveling, and leaving a travel itinerary with a trusted friend  with instructions to take action or come to the rescue if necessary.

it is also a good idea to inform the administration in the area to be visited of the individual or group's experience, the size of the group, the equipment that will be brought, the itinerary, and the expected return date - this information will facilitate a rescue in case of an accident.
