The colors were affected in different area by the late freeze many areas had in June. At my place in Leadville the leaves were almost out when it hit...turning everyone of them brown and making them fall off. As aspens will do...they releafed....however, the second set of leaves were very small and they turned brown this Fall almost overnight and fell off the trees without changing to their normal gold.
Here in the Vail Valley the trees were unaffected by that cold snap and we had some of the most intense color I can remember in years.
thanks again for the pics
