It looks like a maple

Have you seen the flowers or fruit? The leaves look similar to Maple...maybe a striped maple?

Acer rubrum.

No flowers. No fruit. No berries or seed pods...

I orig thought it was some type of maple...the leaves on the striped maple look similar but the bark on the tree looks nothing like that of a striped maple. Bummer. At first glance I thought we had it :-)

The leaves on the "acer rubrum" are too serrated (sp?) I think... the leaves on my tree are smooth around the edges with the exception of the 3 points.

Thanks for all your responses and suggestions :-)

Actually it might be a trident maple.

Leaves on Acer rubrum can be highly variable, btw.
