Thank you that is an interesting read. It almost seems to be a part of another document I found
In the article they quote that the water level has receded nearly 800 feet over the ten to twelve mile distance to the current shores. Using Google
Earth and the elevations I come up with about 100 feet over the same ten to twelve mile distance. While the accuracy of Google Earth may be
question... one thing still remains.
Water levels... for the levels to have been high enough for Puma Punku to have been a lakeport, the lake would have stretched well into what is now
Lake Poopo. The majority of Southern area of the Alto Plano would have been lake. Using Google Earth and elevations one can get an idea of where the
lake front property would have been.
Timing...(High/Low)..Through an article I found HERE
we can get a general
sense of lake levels since the last glacial maximum. There is a possible time when the lake could have been low enough for an underwater city. I
remain skeptical about underwater ruins until allot more documentation can be found. None the less the dates provided here can give some insight.
After analyzing all three core samples, the scientists concluded that the lake - and therefore the entire Altiplano - has undergone a series of
dramatic changes since the Ice Age was at its peak between 26,000 and 15,000 years ago. ``Lake Titicaca was a deep, fresh and continuously overflowing
lake during the last glacial stage,`` according to the Science study, ``signifying that the Altiplano of Bolivia and Peru and much of the Amazon basin
were wetter than today.`` Then, about 15,000 years ago, the Altiplano underwent a significant change. A dry era was launched, which continued for the
next 2,000 years, causing Lake Titicaca to drop significantly. Between 13,000 and 11,500 years ago, Titicaca began overflowing once again. This wet
period was followed by 1,500 years of relative dryness, followed by another 2,500 years of heavy precipitation as the lake again rose to overflow
levels. Then, about 8,500 years ago, the lake level fell sharply as the Altiplano again became dry. But heavy precipitation would return for another
1,000 years, only to be followed by an extremely dry period between 6,000 and 5,000 years ago, during which Titicaca fell some 250 feet below its
present-day level - its lowest level in 25,000 years. Titicaca finally began rising again 4,500 years ago. Since then, the southern portion of the
lake has overflowed its banks numerous times.
I was able to find one graph of a sediment core that showed a tephra layer in it, but it did not give any dates. That page since has become lost in my
bookmarks. I will have to do some digging to find it again.
Edit: It is also possible that the Desaguadero River which is the outlet of the lake at some point in the past may have been much higher, allowing
for higher lake levels. Over time the outlet could have eroded down with progressively lower lake levels, to it's present point.
