Kenny, The Audubon Field Guide series has a book for the Eastern US and the Western US. These books have pics of bark, fruit, flowers, leaves, a pic of the trees skeleton and a good written description of twigs, buds, habit, culture and native area. It is in a pocket book size so you can take it along with you.
Also, your local Cooperative Extension Service agent might walk your land with you and help you ID your trees.
