My guess is elderberry.

Guess I should have tried a google before I posted! Just figured out it is an ash, though of the variety I can't be sure. Anything I need to know about the ash before I decide if it stays? It is in a place that gets sun to part shade, somewhat dry soil, and it is about 25' away from the house.

Yes, I agree that it looks like an Ash. I know nothing of Utah so I can't really comment on what it would like in your area. I would try to figure out which kind of Ash it is and how that tree grows in your area.

Looks like Green Ash is the most likely candidate if it seems to have grown there naturally.

Here is a link that might be useful: Green ash
