Environment: The Grand Canyon Is Losing Its River

Long shadows are in the foreground of a view of the reddish canyon walls, which loom on either side and ahead. The sky is blue with ribbed white clouds.

The New York Times (June 6, 2023) – Down beneath the tourist lodges and shops selling keychains and incense, past windswept arroyos and brown valleys speckled with agave, juniper and sagebrush, the rocks of the Grand Canyon seem untethered from time. The oldest ones date back 1.8 billion years, not just eons before humans laid eyes on them, but eons before evolution endowed any organism on this planet with eyes.

The Grand Canyon, a Cathedral to Time, Is Losing Its River

Written and photographed by Raymond Zhong, who joined scientists on a 90-mile raft expedition through the canyon.

About half a dozen people with orange life jackets ride a blue raft on a murky, brownish and somewhat choppy Colorado River. Rust-colored canyon walls loom on either side and ahead of them. Three other rafts are in the distance.

Since 1963, the Glen Canyon Dam has been backing up the Colorado for nearly 200 miles, in the form of America’s second-largest reservoir, Lake Powell. Engineers constantly evaluate water and electricity needs to decide how much of the river to let through the dam’s works and out the other end, first into the Grand Canyon, then into Lake Mead and, eventually, into fields and homes in Arizona, California, Nevada and Mexico.


Spend long enough in the canyon, and you might start feeling a little unmoored from time yourself.

A spring that looks like a narrow waterfall cascades out of a hole in a canyon wall down into a calm part of the Colorado River. The canyon walls are rust-red.
North Canyon, and a spring at Vasey’s Paradise.

The immense walls form a kind of cocoon, sealing you off from the modern world, with its cell signal and light pollution and disappointments. They draw your eyes relentlessly upward, as in a cathedral.

You might think you are seeing all the way to the top. But up and above are more walls, and above them even more, out of sight except for the occasional glimpse. For the canyon is not just deep. It is broad, too — 18 miles, rim to rim, at its widest. This is no mere cathedral of stone. It is a kingdom: sprawling, self-contained, an alternate reality existing magnificently outside of our own.

And yet, the Grand Canyon remains yoked to the present in one key respect. The Colorado River, whose wild energy incised the canyon over millions of years, is in crisis.

Costa Rica Views: The Tiny ‘Volcano Hummingbird’

Nature on PBS (March 27, 2023) – No bigger than a human thumb, the volcano hummingbird exists only in the Talamancas.

The volcano hummingbird (Selasphorus flammula ) is a very small  hummingbird, native to the Talamancan montane forests of Costa Rica and western Panama.

This tiny endemic bird inhabits open brushy areas, paramo, and edges of elfin forest at altitudes from 1850 m to the highest peaks. It is only 7.5 cm long. The male weighs 2.5 g and the female 2.8 g. The black bill is short and straight.

The adult male volcano hummingbird has bronze-green upperparts and rufous-edged black outer tail feathers. The throat is grey-purple in the Talamanca range, red in the Poas-Barva mountains and pink-purple in the Irazú-Turrialba area, the rest of the underparts being white. The female is similar, but her throat is white with dusky spots. Young birds resemble the female but have buff fringes to the upperpart plumage.

The female volcano hummingbird is entirely responsible for nest building and incubation. She lays two white eggs in her tiny plant-down cup nest 1–5 m high in a scrub or on a root below a south or east facing bank. Incubation takes 15–19 days, and fledging another 20–26.

Ecuador Views: Tortoises In The Galápagos Islands

CBS Sunday Morning (March 19, 2023) – We leave you this Sunday with giant tortoises on Santa Cruz Island, in Ecuador’s Galápagos National Park. Videographer: Alan Golds.

There are 13 living species of Galápagos tortoises, which are also sometimes called giant tortoises. These reptiles are among the longest-lived of all land vertebrates, averaging more than a hundred years. The oldest on record lived to be 175. They are also the world’s largest tortoises, with some specimens exceeding five feet in length and reaching more than 500 pounds.

Giant tortoises were once so abundant on the Galápagos archipelago off Ecuador that the Spanish sailors who explored the region in 1535 named the string of islands for them. (The Spanish word for tortoise is galápago.) Although the islands were once thought to be home to at least 250,000 tortoises, only about 15,000 remain in the wild today.

Conservation: The Farne Islands And Long Nanny In Northumberland, UK

National Trust (March 13, 2023) – In the first episode of The Wild Life, a new series of nature films from the National Trust, presenter Levison Wood explores one of England’s most important seabird colonies. The Farne Islands, off the Northumberland coast, have been cared for by the National Trust since 1925 and are a breeding site for 23 species of seabird, including 43,000 puffin pairs.

The islands are also home to grey seals with around 2,000 pups born every autumn. With an introduction from presenter Julia Bradbury, this film explores the Inner Farne, where you’ll see dive-bombing terns, a medieval chapel and a Victorian lighthouse. Levison finds out what life is like for the rangers who had to deal with the devastating impact of bird flu. He also learns more about the work being done to maintain and protect the area’s fragile ecosystem, address the impact of climate change, protect bird nests and monitor species.

Parts of the Farne Islands may be closed to the public and landing on the islands may not be possible due to bird flu. If closures are in place, you can still experience the islands on a boat tour. Please check the website before you visit: Farne Islands | Northumberland | National Trust With your support we can continue to care for coastal places like The Farne Islands.
