Reply #5: Why does the smoke stop at the Mexican border?

[harlinchi]

Is anyone asking whether the type of development in the area is a factor in the level of fires seen? It cannot be possible for the terrain or climate to undergo that significant of a change over that short a distance. I see brown coloring further south. Maybe it's a sandstorm or something. I see very little smoke.

Reasons? Developmental differences between Mexico and the US? Arson in the US?
