It is probably a Hemlock from Mt. Hood though it is possible that there is a native sub-species. I know there is one from a place called Iron Springs in California. However; Hemlocks are Hemlocks and they do not back bud too well. I would start working on some styling for this tree starting with the removal of the lowest branch down on the left that you have proped up. Take the branches up high, put some decent weight wire on them and start pulling them down, curving the branch tips upward. You need to tighten up the growth pads and give them some shape and you really do need to do it now. Hemlock do not grow into an idea, they grow all over the place, they have to be forced into it while those results are still achievable, the wood is soft and the end points are still green and soft.
Sorry Just realized I need to pay with a tree photo.
