Patch of Blue



The sky closed up this evening leaving this little opening in the clouds. It may rain later. At the least we will get some wind and perhaps a lightening display.

Watched a program on KAET, the PBS channel here in Phoenix, called Saguaro: Sentinel of the Desert. Was not a recent production, from 1989, though one was able to interpret issues of climate change in the Sonoran Desert without the hysteria of "global warming."For instance the droopy arms of this giant were caused by a freeze sometime in the past.

The greatest threat to the Saguaro is loss of habitat. Grasses imported to feed cattle have encroached on native habitat and greatly increased the occurrence of wildfires. The Saguaro can be fatally damaged by fire.
