The Park Rangers team is in charge of:

– Keeping the order 
– Checking cleanliness
– Controlling the Mt Aconcagua camps
– Helping and informing climbers
– Controlling the service providers (in case of problems or complaints report immediately)
– Exercising power of police *
– Coordinating evacuations **
– Checking admission permits (in Horcones and Punta de Vacas)
– Controlling waste collection (of individuals and service providers)

These are some of the duties, among other.

* When the park ranger or physician judge that the climbers’ equipment or physical conditions are poor, they will be advised in writing “Not to ascend”.

** Together with the medical service and the rescue patrol to the park exit. Evacuations will be coordinated by the medical staff in charge of emergencies, by the means they consider necessary or which are available (mules, helicopters, ambulance).

The responsibility for control and watch only includes from the Mt Aconcagua park entrance to the base camps (4300 meters above sea level). Beyond that altitude, they perform only evacuation and cleaning duties. For all these tasks, the park rangers have an adequate equipment and modern communication systems which allow them permanent radio coverage all over the park in VHF to prevent emergencies. The radio frequency is 142.8 MHZ FM.
