This book, in honor of the centennial of the Save the Redwoods League, is a love story regaling the country’s tallest trees, the coastal redwoods and the giant sequoias farther inland.

Five years ago I visited for the first time the “Puebloan Heartland,” defined in this book as the area between Mesa Verde to the north and Chaco Canyon to the south. I knew of Mesa Verde National Park and Chaco Canyon National Historical Park but was unaware that these famous Ancestral Puebloan places bounded other sites of archaeological significance. My wife suggested we visit Aztec National Monument, which puzzled me. What were the Aztecs doing way up here in northern New Mexico? Aztec turned out to be a remarkable site, and I knew I had a lot to learn.

Bison, wolves, grizzly bears, and elk are all categorized as “charismatic megafauna.” These are animals that have popular appeal to many and are often used as symbols of wildness. Not so often mentioned under this category is the mountain lion, also known as the puma, the panther, and the cougar. And while these big cats often fly under the proverbial radar of wildlife advocates, not only are they out there, but their range is expanding and they’re showing up in some previously unlikely places.

When did we start to hike, as a form of enjoyment as opposed to simply going from point "A" to point "B", and what is the future of the activity? Those are Jeffrey Doran's bookends to his book on the history of hiking.

In this, his second edition, Randall Sanger points out 174 waterfalls in Virginia and West Virginia. And many, of course, can be found in places such as Shenandoah National Park, along the Blue Ridge Parkway, and within the landscapes cut by New River Gorge National River and Bluestone National Scenic River.

This is a lovely, well put-together gem of a book. It is not just another collection of ghost stories or tales of killer bears, meant to terrorize youngsters around the campfire, but a mature, reflective look at six of our national parks: Acadia, Great Smoky Mountains, Rocky Mountain, Yellowstone, Yosemite and Zion.

“These largest trees on earth begin life as seeds about the size of an oatmeal flake yet can grow as tall as three blue whales stacked chin to tail.”

Grandma Gatewood’s story, of how she just “kept putting one foot in front of the other” and wound up hiking the entire Appalachian Trail at age 67 back in 1955, is well-known among long-distance hikers. But… it’s probably not so well-known among children. Jennifer Thermes aims to change that.

This is a book I wish I had encountered, quite literally, decades ago. Now in its fifth edition, The Geysers of Yellowstone by T. Scott Bryan is an encyclopedia of the park's roughly 1,000 geysers.

Most of us go to Yellowstone National Park for the wildlife, the scenery, the amazing geothermal features, or simply for outdoor adventure. Early Euro-Americans visiting the area were amazed by natural features like geyser basins and hot springs on a scale encountered nowhere else in their travels. Ultimately this place became the world’s first national park, but for millennia it had been a place of human spiritual and subsistence importance.

Youngsters are essential to the future of national parks, for they will be tomorrow’s advocates and possibly even stewards. But taking children who can barely ride a bike or aren’t old enough for their learner’s permit for driving into a national park can seem daunting. Hiking in Yellowstone’s backcountry with grizzly bears? Exploring the somewhat technical route to Angels Landing in Zion?

There are multiple wonderful things that Douglas Lorain brings to 100 Classic Hikes: Montana. Good descriptions and beautiful photography are crucial to any guidebook, and they’re plentiful here. Toss in a little attitude, and you have a guidebook that strives to give you the lowdown truthfully, not simply to fill pages.

I first heard Allen Steck’s name when I was flying and climbing in the Owen’s Valley of California in the early 1980s. His exploits, along with Norman Clyde, Doug Robinson, Galen Rowell and John Salathe, were legendary. Known by the moniker, the Slim Fox, the mountains have been his home.
