"Thanks for the alder info I have heard of and read about alder for smoking but we dont have it around here I will get out the tree book so I can identify it out west thanks again"
The genus is Alnus.
The most widely distributed Alder is white alder, or, Alnus rhombifolia, followed by gray/mountain alder, or Alnus incana. The latter can be found up to about 8,000 ft; the former, to about 5,000. There are five other species or subspecies, but they have narrower distribution, limited mostly to the northern coast and northern ranges of Ca. The first two extend variously into Canada, up through Idaho, and from southern Ca east as far as New Mexico.
If you're in the Sierra Nevada at an elevation low enough for fires to be legal (and without any other fire restrictions regardless of elevation), and it's in a place where collecting wood is legal, but high enough to find mountain mahogany (Cercocarpus ledifolius), you'd be hard pressed to find a more magnificent wood for adding flavor. I don't encourage it, as they are very slow growers, but they're common enough that it wouldn't be the end of the world if you did.
