Hard to tell from one picture, but it looks like walnut. The sapwood is actually quite pale, the heartwood is the dark color we all think of, but it can get quite washed out with light exposure while drying. Depending on how deep that dark brown actually is, it could also be butternut.

Definitely a member of the walnut family. If it is soft and lighter-toned, butternut. If it is just a little bit lighter than what we generally think of as walnut (‘black walnut’), then it could be common (or ‘English’ walnut) – not native, but in places like New England it was planted here and there, so you might come across it in a more urban setting. Pretty rare though. Most likely, it is eastern black walnut with a bit of sun-bleaching on the ends.
