Here are some images of those wind-thrown Saguaros from the far west side of Avra Valley & to the ESE of the Waterman Mtns.( approx. Lat. 32 degress, 19 mins. N. & Long. 111 degrees, 25 mins. W. ) These all were leveled by the same event prior to their discovery by two pilots returning to their home base in Avra Valley on Saturday, 10 September 2011.
I figure this was the result of either a “gust front” or a “microburst”!
The jpg 3900s are from one area – “blow up” jpg 3923 to see “fallen troops” strewn about the back-ground slope. Only a few of those have had significant enough “freeze damage” to aid their falling. West is approx. to the left in these three images.
In the background of jpg 3821 at the ground horizon line in the mid-level background and partly “eclipsed” by the twin branches on the left side of the Palo Verde tree, is another fallen Saguaro.
These are two Saguaros of a “group” of five that are in relatively close( in sight of each other ) proximity to one another. The area of wind-thrown Saguaros reaches from behind this image to, at least, the “pass” to the left of the small dark hill on the horizon. The view is towards the NE.
