On hard maple the center will have a redish-brown center and on soft maple the center will be more of a gray-silver color. At least that's what the grader at the log yard pointed out to me when I sell a few logs along.
Thanks. If that's accurate, that will be a big help.
Found this book in my wife's collection:

Lists 10 different types of maple around here with Sugar (hard) Maple and Silver & Red Maple (soft) being the most common.
Sugar maple: mature bark grey, irregularly ridged, sometimes scaly; wood light yellowish-brown
Silver maple: young bark grey, smooth; mature bark grey, often shaggy with thin strips that peel from both ends; wood pale
Red maple: young bark light grey, smooth; mature bark dark greyish-brown, scaly, with thin plates that peel from both ends; wood pale brown
Soooo, at what point in a maple tree's life is it considered mature?
