A few weeks ago, Trips brought you photos of The Most Alien Landscapes on Earth. Now, a sequel, focusing this time on scenes shaped by the hand of man.

The Door to Hell, Darvaza, Turkmenistan

The collapse of a natural gas cavern in 1971 created this crater in a small Turkmenistan village. Officials made the call to ignite the noxious fumes...which have yet to stop burning. Photographer: minifastcar33


Windfarm, San Gorgonio Pass, California, USA

Modern wind turbines and an eerie moonrise conspire to create this otherworldly scene.Photographer: Caveman 92223


Sedan Crater, Nevada, USA

In the early '60s, the U.S. government experimented with using nuclear bombs in massive construction works. Among other results was this, one of the world's largest human-made craters.Photographer: itjournalist


Libyan crop circles

Not all crop circles are made by aliens. These plots in Saharan Libya are created by nothing more mysterious than pivot irrigation.Photographer: futureatlas.com


Burgan Field, Kuwait, 1991

During the Gulf War, parts of Kuwait's vast Burgan Oil Field were set ablaze.Photographer: National Oceanic and Atmospheric Administration


Coal mine in Germany

Rio Tinto, Spain

Leached iron and other heavy metals (another result of mining) give Spain's Rio Tinto its name.Photographer: Serafin-Sanchez


Route 61, Centralia Mine Fire, Pennsylvania, USA

Another ignited mine that just won't quit, the fire smoldering under Centralia has forced the evacuation of pretty much the entire town. Photographer: jesiehart


Ground Zero, New York City

Oil slicks

It doesn't take a headline-grabbing oil spill for petroleum to hit the water. Day-to-day extraction and processing operations leak plenty, as shown in these NASA images of Venezuela's Lake Maracaibo (above) and the Arabian Sea (below).Photographer: Visible Earth, NASA
