A new study tackles the mystery of the missing rocks at the bottom of the Grand Canyon. Scientists call this feature the Great Unconformity. It’s a billion-year-chunk of history that somehow eroded away, and now, scientists think they know why. KNAU’s Melissa Sevigny spoke with geologist Barra Peak at the University of Colorado-Boulder about her findings.

About 30 miles north of Flagstaff sits one of the region’s most magnificent-yet-perplexing geological features. Red Mountain is a cinder cone that formed nearly 750,000 years ago in the San Francisco Volcanic Field.

The Flagstaff Festival of Science begins today and it’s all about astronauts. The theme is To the Moon and Beyond in honor of the 50th anniversary of the Apollo moon landings. It takes a lot of people to launch an astronaut into space, and one of those people is Flagstaff geologist Lauren Edgar of the U.S. Geological Survey. It’s her job to train future astronauts in geologic field work, using Northern Arizona’s volcanoes and lava fields as a kind of stand-in for the Moon and Mars. Mars even has its own supersized Grand Canyon called Valles Marineris. KNAU’s Melissa Sevigny spoke with Lauren Edgar about her work with the most recent class of astronaut candidates.

NASA astronaut candidate Jessica Watkins recently came to Flagstaff for geologic field training training along with astronaut Don Pettit. He's spent a year on the International Space Station. KNAU put the experienced astronaut and the future astronaut together to talk about the thrill of space travel.


Earth Notes: Pipestone—Red Argillite

For centuries, Native Americans have cherished a compact, fine-grained clay called pipestone. Its common name comes from their use of larger pieces of it to carve ceremonial pipes.

This week we’re celebrating the 50th anniversary of the first Apollo moon landing, and its unique connection to Northern Arizona…. If you were born before 1969, chances are you remember exactly where you were when announcement came that “the Eagle has landed.” Flagstaff resident Karen Malis Clark does. She was thirteen years old at the time and her father was literally a rocket scientist. He built an escape rocket for the Apollo astronauts to use if something went wrong during launch. In the last segment of our series this week, Karen Malis-Clark shares a bittersweet memory about her father and that time in history.

This week we’re celebrating the 50th anniversary of the Apollo moon landing, and its unique connection to Northern Arizona. Every astronaut who walked on the moon first came to Flagstaff to train. That’s partly because it was home to the U.S. Geological Survey’s Branch of Astrogeology, founded by geologist Gene Shoemaker. Shoemaker’s secretary, Jody Swann, remembers what it was like to work there during the heyday of Apollo…and mapmaker Ray Jordan recalls the Surveyor missions, unmanned spacecraft that went to the moon just before Apollo. They’re today’s voices in our weeklong series.

This week we’re celebrating the 50th anniversary of the Apollo moon landing and its unique connection to Northern Arizona. Everyone who walked on the moon first trained in Flagstaff. That’s partly because the U.S. Geological Survey’s Branch of Astrogeology was here. Carolyn Shoemaker’s late husband Gene founded the branch. She remembers that exciting time in history. Gerald Schaber was a geologist with the branch and trained crews of astronauts of Northern Arizona’s dramatic landscapes of volcanoes and craters. They’re today’s voices in our weeklong series.

This week we’re celebrating the 50th anniversary of the Apollo moon landing. Everyone who walked on the moon first trained in Flagstaff. We’re hearing stories from the people who worked to make it happen. NASA estimates it took more than four hundred thousand people to get Neil Armstrong and Buzz Aldrin to the surface of the moon. Baerbel and Ivo Lucchitta were two of them. A husband-and-wife team in Flagstaff, Ivo taught geology to astronauts at places like Sunset Crater and Meteor Crater, while Baerbel made detailed maps of the moon. As young scientists they’d studied the geology of Earth, but were swept up into the Space Age after hearing the unmistakable sound of Sputnik, the first satellite in space.

This Saturday marks the 50th anniversary of the Apollo 11 moon landing. In many ways that “one giant leap” onto the Moon started off in one small town in Arizona. Every astronaut who walked on the moon first came to Flagstaff to train, in its lunar-like landscape of volcanoes and craters. KNAU’s Melissa Sevigny reports on Flagstaff’s yearlong celebration of its role in the historic moon landing.
