Both Lupines

There are two species of lupine in Sabino Canyon. Hooray! The one above is Desert Lupine (Lupinus sparsiflorus). Occasionally, you'll see one with all white flowers. That's just a variant, not a different species. Lots of these along the road into Sabino Canyon.

This is Elegant Lupine (Lupinus cocinnus). This species has very hairy leaves, as this photo shows well; and it 'likes' the sandy soil of the dam area.
Both are in the Pea family; and both are blooming now. (Unlike many pea-family plants, though, these are not edible. The seeds of the Desert Lupine are particularly nasty.)
