[ RadSafe ] Los Alamos Evacuation & Fire

[Dan W McCarn]

Hello Group:

At least 113,734 Acres (46,027 Hectares) have burned so far, Los Alamos is
still under mandatory evacuation, and there is now some talk about a phased
return, but the schedule has yet to be determined. 

We have 3 dogs, 2 cats and 1 horse with us in Santa Fe.  The evacuation of
over 100 horses, a dozen goats, 5-6 alpacas and quite a few rabbits, ducks,
chickens and turkeys went very smoothly.  Several horses could not be
initially loaded onto trailers and required sedatives to load.  One horse
was injured during the evacuation but is recovering from leg lacerations.

White Rock (a suburb of Los Alamos) was never placed on mandatory
evacuation, but because of the smoke, burned fragments of bark and other
tree fragments and dense smoke, most of the residents have evacuated.
