Context
June 1966. A team of about twenty workers from Chile's National Health Service was camped at Los Morros, in the commune of La Higuera, Coquimbo Region. Patrick Gross places the camp about 160 km from La Serena, at about 1,500 m. That night a medical emergency sent two of them down to the village of Incahuasi. Manuel Muñoz Carvajal drove, with Luis Astudillo Marín beside him.
