"The desert has its own currency and it is measured in water," emphasizes the unique relationship between the desert environment and water resources. In deserts, water is scarce and highly valuable, serving as a vital measure of life and survival in such arid landscapes. The quote highlights how in harsh environments, natural resources like water hold more significance than conventional currency, shaping the way life exists and persists there.

In Terry Tempest Williams' "The Hour of Land," this notion underscores the importance of understanding and preserving vital natural resources within America's national parks. The desert's delicate balance depends on water, making its conservation crucial for maintaining the ecosystem's health and ensuring future generations can experience its rugged beauty.
