Both are 6 x 8, oil on primed paper. Done in the car as we traveled from Las Vegas back to San Diego last month. There was an unusual quality to the sky color to the southwest, and I didn't know the reason for it. Eventually we came upon the smoke plume from the huge Blue Cut fire which was raging in east San Bernardino County. In fact, we were delayed getting through on highway 15 by another fire that had just started. Sadly, it's the new normal.
