    Image: Allegheny stream #3
    Image Owner: Ken Tamminga

    Taken by: Ken Tamminga

    Image: Allegheny stream #3
    Image Owner: Ken Tamminga

    Image: Allegheny stream #3
    Image Owner: Ken Tamminga

    Description:

    I can't get a good enough view into this thicket; my sense from the branching structure, and the available light, is that it's sumac. Still, compound leaf could suggest ash or black walnut. Any thoug...
