Critics of the drought theory question the spatial patters of drought and its relation to the timing of the degradation of Maya city-states. Archaeological research demonstrates that while many regions of the Maya Lowlands were indeed abandoned during the eighth to eleventh centuries CE, others regions only experienced minor disruption, or even flourished .[33][28] Although the spatial patterns of societal collapse are complex, population centers continued in many coastal regions and in the northern Yucatán Peninsula, including as Chichen Itza, Uxmal, and Coba, whereas most states in the central regions collapsed and landscapes were depopulated. The reasons for this spatial heterogeneity in societal disintegration are largely unknown, but researches have hypothesised that central regions may have been more affected because of a very deep water table (which would have exacerbated the effects of drought), or that the longevity of the northern regions was likely facilitated by access to the coast, and thus trade routes.[28]
