Perhaps the greatest Maya mystery of all is the cause of the civilization's abrupt decline. The last dated stela erected at Tikal was put up in A.D. 869; the last anywhere in the Maya world, in 909.
During the Spanish conquest of Mesoamerica in the 16th century, the Catholic Church's Friar Diego de Landa supervised the burning of hundreds of Maya codices - fig-bark books rich in mythological and astronomical information. Only four Maya codices are known to have survived.
When you sling a saddle atop a llama's back, just after he's rolled in the dirt to scratch the unscratchable tickle of having lugged an ungrateful hiker's 90 pounds of impedimenta another eight miles along the trail, you're struck by how matted, coarse, and snarly the wool seems. But that's why it makes for versatile outdoor wear.
I knew that alpaca wool, with its cashmere-soft weave, had been transformed into cuddly knick-knacks ranging from pillows to teddy bears. But through selective breeding over the past 6,000 years, alpacas have so diverged from their llama cousins as to become quite different animals.
As scientific research demonstrates, llama wool's very coarseness and its range of fibers from fine to thick mean that it can be woven into clothing that's superior to down, fleece, sheep wool, and alpaca wool in criteria ranging from warmth to water resistance to usable life.
