If you find an oak with a shaggy, flaky bark, it's probably a white oak or swamp white oak.
White Oak
Swamp White Oak
The leaves of the two are very different. The white oak has lobed leaf edges.
The swamp white oak has leaves more like a chesnut tree.
The acorns of a white oak are about the size of the end joint of a little finger and kind of egg shaped, much longer than round. Swamp white oak acorns are much larger, more the size of the end joint of your thumb, or larger. White oaks produce acorns about every 2 years.

Members of the Red Oak family have a smooth, by comparison, bark that will give you a road rash type wound if you slide down one. Their acorns are smaller, maybe a half inch long, round but flattened on the top and bottom.
