Tree Down - Good for firewood?

Can you  help me identify this tree? It fell in my neighbor's yard, and I'd like to use it for firewood - if its good for that. Its about 45 feet long, and the diameter at the base is about 50 inches.

Below is a close up scan of some leaves, and below that are some overall images of the situation. You can email me or call me.
