The Quaking Giant

On the western edge of the Colorado Plateau, in the mountains of central Utah, is a tree that weighs an estimated 13 million pounds—as much as three giant sequoias, or 55 blue whales, or 10,000 grizzly bears. (Hey, I just thought you might like to imagine a pile of 10,000 bears.) This tree is the […]

Why Rachel Carson Still Matters

On Monday, the Trump administration instructed U.S. Environmental Protection Agency staffers to freeze all of the agency’s grants and contracts—cutting off financial support for many state and tribal environmental protection programs. (Staffers were also told not to discuss the freeze with anyone outside the agency, but the news was quickly leaked to both ProPublica and the Huffington […]

The Freshwater Bullies of Gatun Lake

It is, as Jake Sigg puts it, “a big, grand, old tree.” Tall, gnarled, stripey-barked, with white flowers like sea anemones, blue gum eucalyptus are characteristic of the San Francisco Bay area, despite being native […]

Why Trump’s Victory is like the End of the Ice Age

  In light of who became president elect last week, I find myself searching for patterns to understand what might be happening, and what’s next. I don’t presume unrelated processes mirror each other, but there are uncanny resemblances. In this case, I believe Trump is the end of the Ice Age. He is — I believe, I hope […]

A Wolf Dies

“The Silver Lake Wolves” sounds like the title of a young adult novel, or possibly an indie rock band with lots of close harmony and beards. Actually, it was the name given by the Oregon Department of Fish and Wildlife (ODFW) and the US Fish and Wildlife Service (FWS) to a small family of wolves […]
