Earth Notes - Recycled Glass

Flagstaff, AZ –

What's done with used glass depends in part on where you live. Flagstaff's eight glass drop-off sites collect about 70 tons of mixed glass each month. But there's no glass manufacturing plant in the area. Instead, the glass is crushed into tiny pieces at a recycling center.

Earth Notes - Thomas Moran

Thomas Moran, \"An Arizona Sunset Near the Grand Canyon,\" 1898

Flagstaff, AZ – Born in England in 1837 and raised in Pennsylvania, Moran first came out west in 1871, with the Hayden (HAY-DUN) Survey in Yellowstone. His paintings were the first images most people had ever seen of that region, so powerful that Congress declared Yellowstone the world's first national park a year later.

The legislature then purchased Moran's monumental painting "Grand Canyon of the Yellowstone," a full 7 feet by 12 feet in size, to hang in the Capitol.

Earth Notes - Pasture Restoration Project

Flagstaff, AZ – Earth Notes: Pasture Restoration Project

A thousand years ago, Sinagua farmers channeled water from Montezuma Well onto their fields of corn, beans, and squash. Nineteenth-century Anglo farmers enlarged the fields, improved the irrigation ditches, and tapped into the same spring. In 1943, the Well became part of Montezuma Castle National Monument. Yet cattle grazed the land around the Well into the 1990s.

Earth Notes: Sunset Crater Penstemon

Flagstaff, AZ –

Living conditions are harsh among the cinders in the volcanic terrain that spreads northeast of Flagstaff. But for one plant they're an irreplaceable home. The Sunset Crater penstemon, or Penstemon clutei (pron. cloo-tee-eye), lives nowhere else.

That selectivity has made the plant rare only 36 wild clumps are known to exist. The Center for Plant Conservation has made it an officially "sponsored species" with its own endowment.

The climate and varied topography of the Colorado Plateau shape many aspects of the natural world, including some on spectacular display high overhead.

During dry times of year, lenticular clouds often form over southwestern mountains. Formed where high ground pushes up large standing waves of air, they have very clearly defined shapes and appear to stay in place even as the wind blows.

Earth Notes- Roadrunners

Flagstaff, AZ – Earth Notes: Roadrunners

Roadrunner images are almost impossible to avoid in the American Southwest. Thanks to the famous mid-century cartoons by Chuck Jones, this distinctive bird became one of a select group of creatures known as much through its animated presence as through real animals. The real thing doesn't say "beep beep" but it is a pretty intriguing character too.

Earth Notes - Lava Tubes

Flagstaff, AZ –
Pitch black and cool year round, lava tube caves might seem like an inhospitable place to call home. But scientists are discovering that lava tubes shelter a surprising variety of organisms, some of which live nowhere else on earth.

A lava tube forms when molten lava flows over the ground, then cools and hardens from the outside in. The hotter, inner lava flows away and leaves behind a tube-like cavern. Lava River Cave near Flagstaff, the longest known lava cave in Arizona, stretches a mile underground.
