The fall colours continue to amaze, though the leaves were blowing off the ash trees and drifting down around me today while I worked outside.  Some maples are especially red this year, apparently because we've had a dry September with cool but not freezing nights.  That sort of weather promotes the formation of anthocyanins which make the red colours.

The virginia creeper has been looking bright red for 2-3 weeks, tangled over the trees and shrubs where it's grown.  Looks a lot like poison ivy, but with 5 leaves.

Other maples just look yellow or orange, but the combination of all these colours is making the valley a thanksgiving wonderland.  There'll be hundreds of people out walking to see the fall colours this weekend.
