Ethnographic study of the Haughton Crater Mars analog expedition
Haughton crater is located near the coast on Devon Island, about 500 miles north of the
Arctic Circle and 900 miles south of the North Pole. The crater is about 20 km in
diameter and was formed by a meteorite impact about 24 million years ago. The
Haughton-Mars Project (HMP) in 1998 was an expedition to Haughton Crater, organized
by Pascal Lee, a NASA astrogeologist. The crater was chosen because its breccia and
permafrost-created formations are similar to what we see in photographs of Mars. Thus,
Haughton’s icy crater environment is a “Martian analog.” Twenty four people
participated in the HMP-98 expedition, arriving in 3 phases from June through July.
During the ten days of phase 3, I carried out an ethnographic study of the expedition’s
activities. This included extensive photography. Figure 1 shows an overview of the base
camp, which is a good place to get started in understanding how an ethnographer sees the
world.

Notice in Figure 1 that the tents are not placed randomly. They are in a curved line, with
two larger tents in the middle. People align themselves to boundaries, they find natural
