Bert Heusinkveld, researcher in Meteorology and Air Quality
Where most of us see a boulder or a steep rock face, Bert Heusinkveld sees a challenge. Like this one, one of the Freyr rocks at Dinant in Belgium. A favourite destination for climbers. ‘How do I get up there? How do I figure it out? That's the essence of it, for me.' It looks deceptively easy when he conquers a rock face. Just look at the films of him bouldering on Youtube (search term: BertNederland). Or have a go at the climbing wall at the Bongerd.
