Balsamorhiza deltoidea

Of the three species of balsamroots found in the Columbia River Gorge, I believe this to be Balsamorhiza deltoidea, or northwest balsamroot, but I could very well be incorrect in my identification. The backlit spikes of flowers are lupine, likely Lupinus onustus – these are a week or two behind the ones in the other photograph, the difference between a flatland exposure with other herbaceous perennials forming a shaded cover and a southern hilly exposure with little competition.

This was photographed at the Tom McCall Preserve at Rowena.
