The desert was in superbloom. Our UFO is a scarlet beehive or hedgehog cactus, Echinocereus coccineus, exploiting a crack in a huge hematitic concretion. There were many concretions on the hillside, each with its resident beehive. The yellow carpet is probably Fendler’s bladder pod: Physaria fendleri.
