Pine Tree

We have a pine tree in our yard that is giving us difficulties identying it. It has needles in bunches of 3 that are 6 inches in length, but we can't find pine cones. How can you have a pine tree without pine cones? The closest match that I could find was the Loblolly Pine. However, it would make more since that it is a Ponderosa Pine since they are common in Idaho. The ponderosa pines don't produce pinecones until they are 7 years old, and our tree is still a young tree.

We will have to observe the tree year round to observe its flowers before making a conclusive decision.
