Interesting that dead leaves laying on the deck with the catkins, aren't the same as the green leaves in the previous pictures.

Can you supply a close up picture of the green leaves?

Also a close up of branch ends for leaf arrangement and trunk bark would be helpful too.

Some sort of hickory??

There are two different trees in the top pictures. One has pinnate leaves and catkins and one has entire leaves that resemble a maple. The debris on the deck has catkins from the former and leaves from the latter.

Ah yes,

I can see the 'maple like' leaves in the third picture.

Still too far away for my eyes. :-)

Not sure if these will help, but this as close as I could get:)

thank you all

Hickory is foreign to me so you'll have to take the others word for it. :-)

Shellbark hickory leaf on my lot.

mine looks similar yet not as big or purplish as yours

Looks like a hickory, to me. Mockernut or Bitternut?
