The Sierra Los Tuxtlas has no rivers that might be considered navigable except by
old fashioned dugout canoes or modern kayaks. But once these Tuxtlas rivers drop
to the below the 150 feet elevation line, some become fairly passable.
The big rivers on the fringes of Los Tuxtlas were one of the lifelines of Los Tuxtlas
until the advent of railroads and highways.
Before Cortes, the fertile land of the deltas of the major rivers gave rise to the Olmec
civilization and allowed them to transport massive statues and commerce goods.
