A very original and eco-minded trip around the world comes from David and Janet Carle who traveled around the world following the 38th parallel in search of water related stories, problems and solutions in a world ever more battling and fighting for this valuable ‘blue gold’

38th parallel team

Between extremes of climate farther north and south, the 38th North parallel line marks a temperate, middle latitude where human societies have thrived since the beginning of civilization. It divides North and South Korea, passes through Athens and San Francisco, and bisects Mono Lake in the eastern Sierra Nevada, where David and Janet Carle make their home.

Inspired by their home’s location and with a occupational background as former park rangers, the couple set out on an around-the-world journey in search of water-related environmental and cultural intersections along the 38th parallel.


Their adventure is extensively chronicled in their book ‘Traveling the 38th Parallel: A Water Line around the World’. It documents their trip as they meet people confronting challenges in water supply, pollution, wetlands loss, and habitat protection. At the heart of the narrative are the riveting stories of the passionate individuals—scientists, educators, and local activists—who are struggling to preserve some of the world’s most amazing, yet threatened, landscapes.


Traveling largely outside of cities, away from well-beaten tourist tracks, David and Janet cross Japan, Korea, China – including the amazing annual Yellow River sand washing phenomenon -, Turkmenistan, Turkey, Greece, Sicily, Spain, Portugal, the Azores Islands, and the United States—from Chesapeake Bay to San Francisco Bay. The stories they gather provide stark contrasts as well as reaffirming similarities across diverse cultures. Generously illustrated with maps and photos,Traveling the 38th Parallel documents devastating environmental losses but also inspiring gains made through the efforts of dedicated individuals working against the odds to protect these fragile places.
