I actually thought the same as you, Lori, but alders here could be very different from ones there so I'm really not qualified.  The lenticels and branch configuration look very alder like to me.

But then I was kinda thrown off too, because I assumed all alders had these kind of "cones", but I guess not.  (At least, all the ones native here do.)

We only have 2 alders here, the ones Cohan mentioned, and they both have persistent cones unlike birches.  Very impressive, Rick - I need to learn to distinguish more trees/shrubs on the less obvious characteristics... thankfully, we don't have all that many species to distinguish!  (Excepting the plethora of willows...) 
Trond, our diversity of alders and birches (4 possible species in this area) isn't a whole lot greater than yours!

You have too many different plants of all kinds in your area, Cohan! Here it is no problem differentiating Alnus and Betula (two species of Alnus (both trees) and three species of Betula (2 trees and one shrub and some common hybrids between these).
Salix is a different matter. Scores of species and hybrids too!

As Lori said, not so many species of trees/treeish shrubs here! Just my greenness at looking at them makes any confusion--and the fact that in the kind of habitat I am looking at, almost everything is bushy multistemmed shrub with smallish leaves!
Nice to think of my area as having an overabundance of species (not bad, I think bordering a couple of different biomes helps, and the often non-intensive nature of local agriculture), but its not really true, just an underabundance of knowledge  :-[
