Now that you know it's Oak , If you look at a piece that has been planed on the face or edge , The pores on Red Oak will be open , and the pores on White Oak will be closed (filled with a sort of foam like the pith of a tree ).It looks like tight rings ( Grown in colder climate, shade or poor soil. ) which usually means harder , more dense wood.Should work out well for you . Red or White , Oak is a good choice for a new bowyer.Not very finicky and easy to work with good sharp tools.
