Welcome to the Rocky Mountain Chapter of
The Explorers Club
We are 130 explorers and adventurers who are passionate about the advancement of field research and the ideal that it is vital to preserve the instinct to explore. Since its inception in 1904, the Club has served as a meeting point and unifying force for explorers and scientists worldwide.
Founded in New York City in 1904, The Explorers Club promotes the scientific exploration of land, sea, air and space by supporting research and education in the physical, natural, and biological sciences. The Club’s members have been responsible for an illustrious series of famous firsts: first to the North Pole, first to the South Pole, first to the summit of Mount Everest, first to the deepest point in the ocean, first to the surface of the Moon – all accomplished by our members.
The Club provides expedition resources including funding, online information, and member-to-member consultation. And our famed annual dinners honor accomplishments in exploration. But probably the most powerful resource available to those who join the Club is fellowship with other members—a global network of expertise, experience, technology, industry, and support.
The Explorers Club actively encourages public interest in exploration and the sciences through its public lectures program, publications, travel program, and other events. The Club also maintains Research Collections, including a library and map room, to preserve the history of the Club and to assist those interested and engaged in exploration and scientific research.
If you are located within the Rocky Mountain region from the Canadian to Mexican borders, you can learn more about joining by logging onto Explorers.org.

Science at Sea: Inside Modern Ocean Exploration
What does it take to explore the ocean in the modern age? Far from shore, in some of the most remote regions on Earth, research vessels operate around the clock, mapping the seafloor, imaging deep geological structures, sampling the water column, and collecting scientific data that will be studied for years to come. Behind every expedition lies a system few people ever see: a fleet of ships operating across the globe, complex operations carried out at sea, and a network that turns raw observations into lasting scientific knowledge. This talk offers a rare, firsthand look inside that world. From the…

Think South: Early Exploration and New Research in West Antarctica and the Thwaites “Doomsday” Glacier
in EventsThe United States Antarctic Service Expedition (1939-1941), also known as Richard Byrd’s Third Antarctic Expedition, is often left out of timelines and history books. While the expedition was cut short by World War II, it made compelling discoveries of huge swaths of the continent. Byrd was one of the most important figures of twentieth century exploration. Leilani Henry’s father, George W. Gibbs, Jr., participated as a crew member on one of the expedition ships, the USS Bear. Gibbs became the first person of his race to step on Antarctica. The expedition had 125 men and 80 dogs. Fifty-nine of the… Explore more…

RMEC Mentioned in Titan Disaster Op-Ed
The recent Titan tragedy appeared in media worldwide and mesmerized the nation, perhaps because the Titan represented a collection of humankind’s greatest fears (drowning, claustrophobia, darkness, cold, a ticking countdown clock, etc.) all wrapped up in a carbon fiber cocoon. By one account, CNN alone had over 100 people interviewed on their network during the week, including Captain McLaren. Coverage spawned unprecedented scrutiny on the use of extreme tourism to fund exploration, whether regulation stifles innovation, and at what cost. It encouraged me to pause and ponder the risks inherent in exploration. This op-ed appeared in the June 28 Denver Post. That version is paywalled, but you can… Explore more…

Rocky Mt. Dinner Breaks Five-Year Attendance Record as Members “Share Their Bearings”
The Rocky Mountain Chapter of The Explorers Club broke a five-year dinner attendance record when it changed up the format of its typical bi-monthly dinners. Instead of one speaker, the evening featured nine speakers – all members – presenting their most recent projects with no more than a five-year look-back of previous projects. Each speaker was given only six minutes to present, creating a type of “speed dating” experience for explorers and their guests. The presenters who came to “Share Their Bearings” were: • Chapter chairman and Expedition News editor Jeff Blumenfeld – Where in the World are Explorers Going? • Citation of Merit winner (2017) George… Explore more…

Andes Rugby Team Crash Recalled 50 Years Later
The Andes crash of Uruguayan Air Force Flight 571 happened exactly 50 years ago on October 13, 1972. A rugby team heading to Chile crashed straight into an Andean peak at 14,200 feet. Sixteen of the 45 passengers survived 72 days trapped on a glacier, isolated from civilization and having to resort to eating the bodies of the dead to survive, drying human flesh on the fuselage in the high altitude sun. In those 72 days, they endured extremely cold temperatures, avalanches, starvation and dehydration and ultimately two of them climbed out of the Andes to bring helicopters to rescue the… Explore more…

Field Trip to Montrose Provides Insight on Petroglyphs, Black Canyon and Siege of Annapurna

in EventsPresented by Peter Van Arsdale, Ph.D. Fjallraven Denver Store, 1510 Platte Street 6:30 PM Free admission, guests welcome (no fee) From a historical exploration perspective, spanning the so-called Age of Discovery, first contacts with previously unknown people have proven fascinating, mystifying, and controversial. At times those discovered have been described as “the Other,” “savages,” or “aliens.” At other times, they’ve been described as “giants” or “superhumans.” This presentation will feature five such contacts, placing each in an anthropological context. Peter Van Arsdale’s first contact will include film footage of the men he and his team encountered exactly 50 years ago. The evocative phrase “Like… Explore more…

Saving the Wildebeest Migration: A Maasai Perspective
in EventsFjallraven retail store 1510 Platte Street, Denver at 7 PM One of the natural wonders of the world is the annual migration of white-bearded wildebeest across the Serengeti-Maasai Mara savanna ecosystem of Kenya and Tanzania. The Maasai people are pastoralists and have herded cattle and coexisted with wildlife in savanna ecosystems for hundreds of years. Changing land ownership is altering open range by increasing the population of other non-pastoral tribes with differing land management practices. Fences are being constructed altering both traditional Maasai herding practices and impeding the wildebeest migration. Maasai are no longer able to kill problem lions to protect their… Explore more…
