The first porters worked independently, dictated their own rules, managed their logistics and went into the summer season through the horcones and cows ravine, settling with their tent and equipment in the base camps and offering their porterage service to whoever I would like to save efforts in its ascent to the summit.
As the Aconcagua park was gaining relevance worldwide in economic, tourist, etc. The provincial state of Mendoza, together with the business sector, issued regulations and imposed restrictive measures on suitable high mountain workers, excluding them. In 2005, the Directorate of Renewable Natural Resources (DRNR) BY RESOLUTION 1332 modifies the regulations for the use of the Aconcagua Provincial Park, according to which since then the porter is prohibited from working independently and can only enter the park through the payroll of employees of a company, this measure made the porter’s job significantly precarious, adding to it a large series of abuses by the employer.
Seeing all this, the workers concerned about their precarious work situation began to meet, several years passed until in the 2008-2009 season the general assembly was held during the season in which more than 60 porters from different companies attended and stayed agreement to create an institution that would give union and strength to independent work. On June 22, 2009, the founding assembly was held to give legal start to the legal person, that day 44 people signed the founding act giving the newly created APA its statute and the 1st board of directors approved unanimously. In the summer of 2009-2010, after a long management and commitment, the APA set up its own camp for the first time in Plaza de Mulas.
