The sand squeaked underfoot as she toed it. She looked more closely: dark grains of basalt, mixed with minute seashell fragments, and a variety of colorful pebbles, some of them no doubt brecciated fragments of the Hellas impact itself. She lifted her eyes to the hills west of the sea, black under the sun. The bones of things stuck out everywhere. Waves broke in swift lines on the beach, and she walked over the sand toward her friends, in the wind, on Mars, on Mars, on Mars, on Mars, on Mars.
