Every year I record the date when most of the trees are bare on my favorite hillside in Schenley Park — the hill at the end of the Greenfield Bridge.
In 2008 the leaves were gone by 2 November. In 2012 Hurricane Sandy stripped them from the trees by 4 November.
Last year the changes happened much later. In 2017, the leaves were still green in late October and more than half were still on the trees on 27 November. Here’s a 2017 slideshow of autumn trees on that hillside.
This year is similar to last so I wonder … When will most of the trees be bare? November 15? 20? 30? Later?

HINT! Two factors that affect leaf loss on this hillside: (1) More than half of the trees are oaks; oaks drop their leaves later than maples. (2) This city location is warmer than surrounding counties.
