Having too much fun with iNaturalist
Some people in Arizona are having far too much fun with iNaturalist. Take a look at this map of Creosote Bush, Larrea tridentata, a dominant plant of the Sonoran Desert. Each dot = 1 posted observation. Zoom in on an area east of the southern end of the border of Arizona and Mexico. 🙂

(There's another north and east of those.)
