Well, whatever these are... they look pretty.

MD...i'm sure Mira Bilis knows more about them than i do but i love white birch...a beautiful tree...

Well girls..... now I can see how they've been publishing Tree News for 40 years!!! There's so much to say about them. LOL!!!!!!!!!!!

Good one MD!  :D

I assumed they were aspens because they thrive in high altitude regions like this place.  I don't think white birch grows as far south as Utah ... but I know they are abundant in your state Trix.  :)

Mira Bilis... in that Tree News there was this little gem:  1 tree can make 10,000 matches. 1 match can destroy 10,000 trees.

i thought they were white birch....

I love the aspen trees.  :)
