Red Maple Fall Leaf Color Changes

Red Maples offer the most impressive color change in my opinion. I've been watching this set of maples near an apple house a few miles away on 52. The colors have stuck in my mind since last fall. The red Maple is at peak while a sugar Maple is beginning to take shape and will become a brilliant yellow.

Maybe it's not a Red maple but a Scarlet Red Maple?

Here's a great source of foliage activity in state parks. The source seems to be very current.
