Anyone recognize what species of manzanita this could be? The bush is about 3 years old, 5-ft in height.

Before I hit every one of the 76 species on this page, I thought I would see if anyone might recognize what species of manzanita this is.

Location is western Calif. Thanks in advance.

Hard to tell from the photo -- the leaves are in bunches of 4 with a thorn in the middle. Each group of 4 alternates on opposite sides of the branch. Branches are reddish brown and green mixed together (photo is pretty true).

Oh, and the thorns are sharp (YEOOOOOWW!!!)
