From Caldera we continue to Copiapo in heavy fog which makes it more difficult to drive. About 20 kilometres from Caldera we come to an interesting place where no cacti were found but only carpets of Tillandsia lembkei. The plants only gets its water and nutrients from the fog! - though they are settled on the ground they don't have any roots at all. Close to Copiapo we find the first population of Copiapoa megarhiza which means the Copiapoa with thick roots. Later in the outskirts of the town we found another population whith healthy grown plants. Unfortunately we didn't observe any young plants or seedlings.
