Host David Yetman and a group of international researchers including some from the Arizona-Sonora Desert Museum, traverse the famed Sea of Cortez. The Gulf of California as it is also known, once showcased the greatest marine diversity in the world.
In this land of enhanced biodiversity, two different worlds come together - the terrestrial and the marine.
On land, visit locals whose grassroots conservation efforts have helped revive the gulf's endangered sea turtle population.
On the beach, wade through the one of the area's many tide pools to get up close and personal with sea cucumbers, flat worms, serpent stars, and sea anemones.
On the water, watch the Bottlenose dolphins playfully accompany a tour of the region's numerous enchanted desert islands.

The islands in the Sea of Cortez are chunks of tectonic debris that highlight the violent geological history of Baja California. In this episode, travel along the coastline of Espiritu Santo Island with host David Yetman, researchers from the Arizona-Sonora Desert Museum and a group of international scientists. Kayak around the island and visit extremely vocal sea lions and navigate the rock canals near the shore of the island that were created in the early 20th century for the pearl oyster trade. On the island, trace tree roots that snake down the canyon walls in search of water and discover a completely new species of beetle crawling across the boulders. Before leaving the island, cross paths with an enormous pack of fiddler crabs scudding their way to a new location.

Loreto Marine Park was established in 1996 to preserve the delicate ecosystems in the Sea of Cortez. In this episode host David Yetman, a group of international researchers and scientists from the Arizona-Sonora Desert Museum explore Catalina Island, a biological reserve within the park. This island is home to terrestrial plants and animals that have been so physically isolated that they have altered genetically and become new species. Here, there is a rattlesnake species with no functioning rattle, a columnar cactus sporting a trunk almost ten feet around and a barrel cactus reaches a height of over ten feet. The park faces huge challenges, including over fishing, overpopulation, and the need to educate the expanding human population about the distinct natural values of the Gulf and Baja California.

Host David Yetman and University of Arizona Geoscientist Susan Beck head to Southern California to trace the San Andreas Fault and examine some of the tortured topography thrown up by the fault. Join them as they follow along the fault near the Salton Sea at 230 feet below sea level and then wind through Painted Canyon surrounded by massive rocks distorted almost beyond recognition by the fault’s relentless movement. Then travel by helicopter to gain the “big picture” of the fault as it forms massive mountain ranges and deep valleys. From here, see how geologists follow outcrops of vegetation to trace the fault line and how the town of Desert Hot Springs lies in relation to the fault. This episode also examines ways of harnessing the energy created by the movements of the San Andreas Fault and some of the human challenges facing people who live along its path.

Host David Yetman and historian Bill Beezley, along with Argentine expert María José Figuerero, team up to travel around the cool arid climates of central Chile to vineyards that have made Chilean wines famous. The trip begins in Santiago’s great central market to take a closer look at some of the local cuisine that pairs so well with the wine and the role wines play in Chile’s traditional family life. From there, the search for wines takes the travelers to local vineyards as owners demonstrate traditional and innovative methods of cultivating grapes. In some cases, chicken, sheep, llamas and alpacas roam through the vineyard providing the land with a natural fertilization. Beezley and Yetman complete their wine quest at the celebrated Viña Montes, a winery designed by a Chilean architect and laid out according to feng shui principles.

Host David Yetman, Argentine Archeologist María José Figuerero and native son of Patagonia, Harry Nauta venture across Argentine Patagonia, encountering landscapes usually cold, isolated and windy, but also spectacularly distinct and colorful. After stopping to admire the camel-like guanacos that roam the area, they pause at a brightly decorated Argentine shrine celebrating Gauchito Gil, the “little gaucho,” a Robin-Hood-like figure to whom devotees from throughout the country attribute with good luck and miraculous recoveries. Later, in the Chubut Province, travel from fossilized trees to fossilized marine life within the space of a few miles and to Bustamante Bay, home to a couple hundred sea lions and tens of thousands of desert penguins as well as thriving sea weed industry.

For 10,000 years people have called Patagonia Desert home, and they continue to do so to this day. In this episode, Host David Yetman, Argentine Archeologist María José Figuerero and native son of Patagonia, Harry Nauta trek inland to examine a cross section of the Patagonia desert from the coastal city of Comodoro Rivadavia into the Andes, finally arriving at the border with Chile. Winds blow typically upwards of 50 kilometers per hour and roads through the desert are stark, but far from dull. The travelers halt to rescue a stray Patagonian Armadillo, inspect gigantic oil pumps that dot the arid plains, tour an abandoned railroad station, interpret tableaus of rock art, and drop in on the harvest at a cherry farm. Join them as they conclude their trip with a Patagonian party filled with vibrant music, traditional dance and barbecued lamb.

In Chile’s Atacama Desert people have lived for thousands of years in a land without any rain. The hyper-arid soil has made the perfect medium for preserving the 9,000 year history of human occupation. Host David Yetman and Archeologist María José Figuerero visit the coastal city of Arica and other nearby towns in search of manifestations of millennia of continuous human habitation. Near the city, the hillsides abound with geoglyphs, gigantic artistic representations of people, animals and symbols. Of special interest are the prehistoric and historic cemeteries of San Lorenzo, where modern graves mingle with those thousands of years old. The highlight of the trip is a stop at the Museo Arqueológico, which houses collections of pre-Columbian ceramics, textiles and skulls, along with a breathtaking collection of people mummified over 8,000 years ago.

In this episode, host David Yetman, historian Bill Beezley and Archeologist María José Figuerero trace the Atacama Desert Trade route from the Pacific coast to the Chilean Andes from sea level to 15,000 feet elevation. Though a modern paved road has replaced the ancient llama caravan trail, the road still connects the goods from the Andes with the marine resources from the coast. Along the route, the travelers encounter evidence of pre-Inca and Inca populations, such as defensive structures, ancient towns, and storage sites. Traditional Incan villages on the road are slowly becoming depopulated, but there are still the unmistakable signs of both Christian and pagan influences on the locals who remain. This program also features a look at the largest herbivores in Chile, the wild vicuñas and guanacos and the domesticated alpacas and llamas.

Host David Yetman, historian Bill Beezley and Archeologist María José Figuerero travel around the Puna, the high-elevation plains of Chile’s Atacama Desert, a harsh environment that is home to traditional villages as well as unusual plants and animals. The first stop is in a small village recently depopulated by crop failures that have forced many natives to depart for the coast. Not far away the travelers pause among the rocks to catch a glimpse of vizcachas, rodents that resemble long-tailed rabbits. Next, visit a zone of active volcanoes four miles high where steaming hot lakes meet sub-freezing air. While there, the travelers spy on flamingos foraging among these steaming lakes and pools as they feed on tiny aquatic animals. The trip concludes at the rainless ocean port of Iquique, which features one of the world’s finest parapent (hang gliding) sites and a popular grassless golf course fashioned entirely from dirt.
