Costa Rica's Corcovado National Park protects one of the world's premier rainforests. Rainforests are somewhat of an illusion. The profusion of growth is built on but a few inches of nutrient-rich topsoil that is consistently regenerated by fallen leaves and other decaying plant matter. Underneath is thick clay that is largely devoid of nutrients. Since rain is abundant and nutrients are only at the top of the soil surface, tap roots that reach deep below the surface are unnecessary. Rainforest trees have evolved to have serpentine buttresses that spread out laterally to gather water and nutrients while at the same time helping to stabilize these giants of the forest. I photographed this ancient wild fig tree at the end of the day as late afternoon sun broke through the forest
