An international team of explorers set out to explore the secrets that lie deep within the largest alkaline lake on Earth. The team was made up of seasoned archaeologists, historians and photographers. Considering that the lake has been in existence for millennia, the consortium of researchers knew that this was not going to be an ordinary undertaking. They all knew that they were going to spend a lot of time on the investigation, and they were well-prepared for it.
Were they the first to do so? No, because a team of researchers had already carried out such an investigation. So what made them stand out? They had learned from their predecessors and were convinced they had a better chance of discovering the truth. The bottom of Lake Van is covered in a layer of mud several hundred metres deep. Every summer, a layer of lime about an inch thick settles at the bottom of the lake. The lime mixes with the pollen grain that floats to the bottom of the lake, forming a layer of sediment. In the winter, clay is deposited on top of the pollen mixture.
