Global warming: Are we doomed? A poll.

[Jackalope]

This picture is quite misleading - perhaps intentionally so.   Being a little more than 200 km from Mazatlan, you might expect that this is a tropical zone.   It is not.  Based on the distance to Mazatlan, this picture was taken somewhere between La Palmita and El Tecuan on Mexico 40 in Durango, this area is over 8200 feet in elevation and snow is not that unusual.

Although snow is uncommon in most parts of Mexico, it does snow each winter in some parts of the country, especially in areas located at altitudes greater than 10,000 feet above sea level. It snows in 12 of the country's 32 states (31 states and 1 federal entity), most of which are northern states. It also snows on mountain peaks and volcanoes, where the snow can be up to 10 inches thick. Some regions that commonly receive snow include the northern altiplano, high peaks such as Iztaccihuantl, Citlaltepetl, and Popocatepetl, and the highland areas such as Toluca, and Durango. Although Mexico City is surrounded by large mountain ranges, it does not receive snow. In fact, Mexico City has not experienced snow in 50 years.

I can't speak to the others, but there is nothing particularly extraordinary about snow in the Durango highlands.
