Tips on photographing Crystal Mill

We are thinking of making a trip over to the mill. We have been there before in the fall but missed colors being there to early. We are looking for some input as to when the aspens there might change and what time of day is really best to photograph it.

Okay, I'm just looking at Andy Cook's book. It says..."Aspen trees in the Marble area often peak the same time as Maroon Lake aspen, usually during the third week of September." and "The lighting is best here in the afternoon."

Andy's book is really great. You can find it here:

Hope this helps.
