Purev's reflection is perfectly captured in the icy water in Altai Mountains, Mongolia, September 2016. Navigate the snowy wilds of Mongolia with this nomadic reindeer herding family. Photographer Joel Santos dived 1000km into the depths of Northern Mongolia to visit the Ganbaa family near Khovsgol Lake. Despite only being able to spend three days in the Tsaatan familyÌs camp, Santos travelled for four days to reach them – three driving and one on horseback – before repeating the epic journey to return home. Travelling with an interpreter and a fellow photographer from Màràn, Mongolia, the photographer met the Ganbaa family, led by matriarch Purev who lives with Buyantogtokh, a widowed reindeer herder.
