Titicaca lake and its ruins

On our second day in La Paz, we took a bus to the village of Copacabana, close to the Bolivian/Peruvian border.

Then we took a boat to the mighty Isla del Sol, located at the heart of the Titicaca lake, the highest navigable lake in the world.

Our interest in the island was the remote incan ruins located at the southern portion.

It was a sacred place since a period earlier than the Inca occupation, back to the Middle Horizon period.

The architecture is a mix between the ancient Tiwanaku style (the earlier inhabitants) and the later Incas. This made the ruins a very unique archeological site to be visited.

While trekking in hills, we stopped close to a local house and while trying desperately to recover my breath, I found something different in the middle of the stones close to my feet.

It was a mollusc fossil shell. A little bit eroded for the millions of years exosed in the high hills of the incan island.

This fossil I accidentaly found belonged to the Lower Tinajani Basin, which lacustrine sediments of the ancestral Titicaca lake were deposited between 18 and 14 millions years ago. But very few is known about this stage of the Tinjani Basin because most of its deposits lays in the bottom of the lake.

We then finished our treeking at the Bolivian island and took our way back to La Paz.

In the next post we will describe our bike ride through one of the deadliest roads of the world.
