See the horizon? Those white vertical not-egrets? They flank the Columbia River at Biggs Junction, great for parasailing and wind turbines.
Found this little gem hugging the ground, with lovely about 3cm diameter flowers. ID conclusion: Lewisia rediviva. Grateful for assistance from iNaturalist, which indicated it was a Lewisia species.
I wondered what the (free!) app would do with this, as it is just vegetation without blooms. But, I thought, it has distinctive configuration. iNaturalist suggested Lithospermum ruderale, and (after comparison to multiple pictures) I concur!
