Photos: Artifacts and Specimens from the Crocker Land Expedition

In 1913, seven American men sailed more than 2,500 miles (4,020 kilometers) from New York to Etah, Greenland, to explore a mountainous Arctic region called Crocker Land that previous explorers had noted but hadn’t had time to reach themselves. The Peary-MacMillan Arctic Museum in Brunswick, Maine, recently opened a new exhibit highlighting artifacts and natural specimen from this largely forgotten expedition.

Making a home in the arctic

Within two weeks of arriving in Etah, the explorers built a house that would protect them through the winter and allow them to prepare for their journey to Crocker Land in the spring of 1915.

An unexplored land

Oceanographic studies of Arctic Ocean currents conducted in the early 20th century seemed to confirm that Crocker Land — the region outlined here to the west of Greenland — did in fact exist, even though nobody had ever ventured there.

Navigating ice and snow

Crew members used this sextant to try to locate Crocker Land, based on descriptions provided by explorer Robert E. Peary. (Credit: Spencer, Browning and Rust, London. Gift of Donald and Miriam MacMillan. Peary-MacMillan Arctic Museum.)

Only a mirage

After about six weeks of trekking over ice and snow, the crewmembers determined that Crocker Land was actually a mirage of snow and ice — similar to this modern photograph of an Arctic mirage — that became stretched and manipulated in the Arctic atmosphere to look like a mountain range.

Snow goggles

Crewmembers wore snow goggles to protect against snow blindness, caused by the bright reflection of sun off of extensive Arctic snow. (Credit: Wood and metal goggles: Gift of Donald and Miriam MacMillan. Glass: Given in honor of Walter E. Ekblaw, Jr., devoted son. Peary-MacMillan Arctic Museum.)

Arctic bees

The men collected hundreds of scientific specimens, including these bees: Bombus hypeboreas, B. balteatus, and B. flavescens. (Credit: On Loan from the Illinois Natural History survey. Peary-MacMillan Arctic Museum.)

Arctic plants

The explorers also collected many plant samples to bring back to the United States for further analyses. Vial 63: leaves of smooth draba; Vial 68: Arctic bell-heather; Vial 71: black crowberry; Vial 74: seeds of dandelion; Vial 76 seeds and heads of cats-paws; Vial 77 plants of cats-paws.

Arctic rocks

Members of the Crocker Land Expedition collected rocks and fossils to document the geologic landscape of the region. (Credit: Given in Honor of Walter E. Ekblaw, Jr., devoted son. Peary-MacMillan Arctic Museum.)

Migration discovery

One of the major findings of the expedition was the northern nesting ground of the red knot, a seabird that nests in the Arctic during the summer and travels south in the winter.

Explorers’ grub

Grapenuts were amongst the many non-perishable goods that the men ate to keep themselves alive during the expedition. (Credit: Grape-Nuts advert. and facsimile. Peary-MacMillan Arctic Museum.)

Exploring the Arctic today

Researchers based at Bowdoin College in Brunswick, Maine, continue to visit the Crocker Land headquarters for anthropological studies. (Credit: John Darwent, Etah, July 25, 2005. Courtesy of the Inglefield Land Archaeology Project. Peary-MacMillan Arctic Museum.)
