The period of darkness in this expansive arid region presents a stark contrast to its daytime conditions. Marked by a significant drop in temperature, this time of day transforms the landscape from scorching heat to a cool, often surprisingly cold, environment. For example, temperatures can plummet from over 100F (38C) during the day to near freezing at night.
This nocturnal transformation plays a vital role in the desert ecosystem. The lowered temperatures and increased humidity support the activity of nocturnal animals adapted to these conditions. Historically, understanding and adapting to these nighttime conditions has been crucial for nomadic peoples traversing the area, influencing their travel patterns, shelter construction, and survival strategies. Navigation, too, has historically relied on celestial observation during this period.
