A long time ago, the earth warmed considerably; now, scientists study fossils to find out what happened – and what it might mean for us today.


A macabre measure of the human footprint

I’m a student of roadkill. I keep an informal tally of the carcasses I spot on the roadside — what kind, how many and where — and I note the splatters that accumulate on our car wi”ndshield. They’re an indication of the diversity and abundance of animal and insect lives along the unnatural transects we…

The end of Western welfare?

As Wall Street’s titans of finance crumbled before our eyes in mid-September (coincidentally, this was Bin Laden’s stated goal after 9/11), I remembered the day I interviewed Bill Yellowtail at his ranch, near Wyola, Mont., 15 years ago, and the shocking things he said that afternoon about capitalism in the West. One of my notes…

Knopf, 2008.   Like wanderers returning to the old hometown after a long time away, readers of Philip Fradkin’s new biography of Wallace Stegner will recognize familiar terrain as well as make fresh discoveries.

Bear necessities

We wound our way up a rocky cliff-side trail toward Gunsight Pass, which straddles a ragged, 7,000-foot-high ridgeline in the heart of Glacier National Park. Forty mph winds buffeted us, and a severe case of “bearanoia” held us in its grip. The rangers had suggested Gunsight Pass because it offered stunning views and a relatively…

The invisible man

Name Ricardo Arriagada Age 30 Occupation Goat herder What herding means, day to day Four hours in the morning and two in the evening, filling water tanks and maintaining and moving the electric fence that keeps the goats corralled. The upside of living alone in a travel trailer on the Bay Area’s exurban fringes “Things…

Wildlife wars

They’ve loped to the southern edge of Wyoming’s Wind River Range, and straggled into northwestern Colorado. They’ve filled Montana forests near Missoula, Helena and Bozeman. They’ve crossed the Idaho Panhandle, padding into north-central Washington and eastern Oregon. And despite disease outbreaks and being shot by the feds for devouring the occasional cow, every year since…

Forget Wall Street, focus on the real issues

We are approaching a crisis that stems in part from irresponsible behavior and is aggravated by our insatiable consumer culture. A lack of government oversight has let the problem grow to catastrophic levels. Now it could devastate entire economies and societies. No, I’m not talking about Wall Street. I’m talking about the crisis we seem…

Acidifying oceans

James Zachos fishes around his desk and pulls out a plastic bag filled with chunks of deep-sea sediments. The sediments, wrested from the South Atlantic in 2003, are 55.5 million years old and ‘deep red in color because they are almost entirely clay. Missing is the abundance of shelly residue that gives abyssal sediments their typically…

Back to the future

The earth warmed considerably some 55 million years ago. What does that tell us about our current climate dilemma?

Biodiversity? Not so much

Your article “McCain: T.R. or W?” contains this statement: “The San Pedro hosts the second-most biologically diverse array of mammals in the world, second only to the Costa Rican cloud forests” (HCN, 9/1/08). As far as I know, no scientists have ever claimed that the San Pedro River had biodiversity second only to Costa Rica.…

“1,000 messy facts”

Riparian systems are varied and dynamic; riparian models are human constructs particular to individuals. Cleo Woelfe-Erskine’s article, “Riparian Repair,” failed to capture a fundamental of reclamation and even restoration: We practitioners don’t deliver a perfect facsimile of nature full-blown at the inception but rather advance the recovery process, which continues if we have been successful…

Unnatural selection

In his letter, Neil Snyder asserts that “it’s time stop intervening on behalf of the spotted owl and let nature take its course, whatever that will be” (HCN, 9/15 & 29/08). If we had allowed nature to take its course, old-growth forests would still blanket the Pacific Northwest. Spotted owls would occupy their traditional niche,…

Taking your life in your feet

Having lived in different parts of Arizona for many years, I would say that it is not just Phoenix that is unfriendly to pedestrians. It is the whole state. Arizona drivers think they own the road and have an inalienable right to speed. In many places, both big cities and small towns, roads have narrow…

Greenwashing, literally

In last issue’s “Two Weeks in the West” article concerning “clean” coal promotion at the Democratic National Convention in Denver, you misattributed the purveyors of “green coal” (coal painted green) to coal company “henchmen” at the DNC (HCN, 9/15 & 29/08). In reality, what was witnessed was an act of political theater by environmentally minded…

Battleground!

No matter who wins in November, one thing is certain about this year’s election: the Interior West has finally arrived. For the last 40 years, campaigns generally flew right over the eight states in the interior. Their sparse populations, relative handful of electoral votes and status as Republican strongholds meant they just weren’t worth fighting…
