Down to Earth With: Geologist Robert Brinkmann

As a child, Robert Brinkmann was always curious about rocks. He wondered how they got where they were and why they were different from each other. Brinkmann grew up in the farm country of southeastern Wisconsin, as well as in the woods in the northern part of the state. After one of his first geology classes in college, he went home and finally understood what he was looking at. “It was such an eye-opening experience to be able to read the landscape,” Brinkmann says.

Everything's bigger in Texas, including the Wink sinkholes

Residents of the neighboring West Texas towns of Wink (population 940) and Kermit (population 6,000) have had decades to get used to a pair of large sinkholes that opened a couple of kilometers apart between their towns, the first in 1980 and the second in 2002. But according to a new study, the ground around the two holes is subsiding and unstable, opening up the possibility that they could collapse into one giant sinkhole.

Rosetta spies cometary sinkholes

Large circular pits seen on comet 67P/Churyumov-Gerasimenko by the European Space Agency’s Rosetta spacecraft may be sinkholes rather than craters left by explosive eruptions or impacts, according to scientists who analyzed images taken by Rosetta’s OSIRIS camera.

Sinkholes: Florida grapples with the wonders of the not-so-deep

This story was printed in August 2010. In response to the tragic sinkhole event in Tampa, Fla., on March 1, we are reposting this story.

Sinkholes are a natural part of Florida’s landscape, forming when rainwater levels fluctuate. They've occurred naturally for millions of years and they haven’t been a big problem for humans until recently: Florida’s population has increased from fewer than 8 million in the 1970s to just shy of 20 million today — and farmers, snowbirds and Mother Nature have begun to engage in an increasingly acrimonious water war. The addition of humans to the landscape has made the situation increasingly volatile. Now, sinkholes open up seemingly — or literally — overnight. When a sinkhole opened up in a cow pasture, few people cared, but now if one opens up under somebody’s house or under Interstate 4, we pay attention.
