Lake
Atitlan is in the Highlands of Guatemala.
It was
born violently, long ago, probably before the emergence of man here.
Scientists still debate the exact nature of its birth, an event which
created a nearly circular depression of 11 miles in diameter, 95 square
miles of area, and over 1,000 feet deep. However, the
consensus is that
Lake Atitlan was
formed in an immense volcanic explosion 85,000 years ago. Like Pompeii and
Mt. St. Helen, volcanic pressure was released with devastating results.
However the explosion here was much more destructive. The explosion at Mt.
St. Helen released 2 cu. kilometers of rock and ash, Pompeii blew out 6
cu. kilometers. Atitlan discharged over 180 cu. kilometers of hot ash and
rock.
The steep sides of the
crater continues deep underwater.
An immense hole was left in the earth's crust, leading to Atitlan being
one of the world's deepest lakes. One of the more interesting
effects of the explosion is that deep, large fissures were formed, out of
which the water flows. Atitlan is unique in that it is a fresh water lake
with no river outlet.
Tens of thousands of
years later three volcanoes grew on the southern shore.
85,000 years ago it
must have been horrendous. Everything died for thousands of kilometers
around. A more dreadful sight is hard to imagine.
It is intriguing to
think that out of such horror came the splendor we see today. |
