Chichen Itza Mexico

Why did the Maya abandon their magnificent temple cities?

Drought?; War?; Spaniard?; Disease? …
no Starbucks? … ??

All of the above?

Maybe none of the above?

Somebody knows. 

As the Spring and Fall equinox sun sets, a diamond-backed snake (shadow)
makes a snaky pattern on the way down the pyramid staircase.
Here people gather and celebrate.
The Mayan may have left their Temple Cities, 
but they did not leave. 
Many still practice their religions
such as Popul Vuh.
And speak their native language and dialects. 
They are still here.
