      Arctic deserts are also a thing (e.g. Iceland). The similarities tell the whole story:

      • Poor access to liquid water
      • Need to insulate body from temperature extremes, wind
      • Food sources are sporadically available at best
      • Need to minimize contact with ground or insulate feet
