RAINBOW CLOUD; Quartzsite-AZ

October 26th: We drove to Parker-AZ this afternoon to grocery shop; on the way to and fro, we were treated to a landfill burn :-(

Landfill on fire between Quartzsite & Parker-AZ

A thumbs up mountain formation ;-)

3 hrs. later …

The stench was awful.

Thankfully, neither of us suffered any breathing issues - though the stench was slipping into Betsy's cab even with the windows tightly rolled up.

Later on, after things were put away and I was walking the shopping bags out to Betsy (where they are kept between shopping trips) … I saw something in the sky I've never seen before. Anywhere.

As far, as I could ascertain, there was no moisture in the atmosphere: it was 91-degrees, and wonderfully warm here, on a Fall day in Arizona ;-)
