Bush/Tree seen in Zion Park, Utah

I made this picture, running along the Watchman Trail in Zion Park, and now I am wondering what was that? Any suggestions?

I think it's an ash (Fraxinus).

 

Taking a cue from what Ron said, I see a page with photos of "Singleleaf ash (Fraxinus anomala) (I think) in Zion national park",
http://www.bomengids.nl/uk/soortenusa/singleleaf_ash__fraxinus_anomala_zion.html
That species is listed as being at Zion.

 

Fraxinus anomala for me too.

 

Thank you all! Looks very reasonable, as I myself photographed it on the same trail two years ago. But that one was with fruits:
