An autumn season peek into the Colorado wood area around the St Vrain River as the season and colors start to change from fall foliage to winter on the way. In Colorado one good wind or snow storm could wipe this all away. But most of the time it is a very long nice weather autumn season starting with the high elevation in mid September and works its way down to the plains that starts in mid October. The days are warm and nights are cool. Good sleeping weather. Photo: © James "Bo" Insogna
