We can find many cactuses around the 4-km point (about at 3100 m asl) on the way from the Operations Support Facility (OSF) at 2900 m asl to the Array Operations Site (AOS) at 5000 m asl. The cactuses began to bloom all together from the end of November. They bear yellowish-white cute flowers vigorously in an inhospitable environment in the Atacama Desert.
