Does that mean a 'minor' drought was in the making prior?
It seems that at least around lake Chichancanab, which is in
central Yucatan about 50 miles south of Chichen Itza, drought
was 'normally' roughly periodic on an approximately 50 year cycle,
but that around 750 one began that lasted at least 200 years.
This dry period has also been found in the Sahel of Africa, so it
is not a smallscale event.
