Adapting to Changing Wildfires: Part One, Backpacking Light, October 2020
What is the future of backpacking in an era of frequent massive wildfires? This year’s giant blazes in the Western U.S. closed many thousands of square miles (tens of thousands of square kilometers) in forests and parks for weeks and months. This essay gives you some background on wildfires in the U.S., describes the potential health and safety risks, and suggests how to stay safer and healthier. |

Sleeping Bag Temperature Ratings, Backpacking Light, September 2020
You’ve probably seen sleeping bags advertised as good to “32 degrees” (Fahrenheit) or “0 degrees” (Celsius) and wondered how they came up with that number. Thanks to measurements using the ISO 23537 standard, commonly known as the EN rating, we have a consistent but imperfect way to measure and report those values. In this column, I’ll review the standard in detail and cover its pros and cons. |

Improving R-values for Consumers, Backpacking Light, September 2020
Sleeping pad R-values are not that useful for many consumers, and the guidance from pad makers, retailers, and gear reviewers is inconsistent and prone to misinterpretation. This is a proposal for improved labeling and marketing that requires further development. |

Backpacking Scissors, Backpacking Light, February 2018
Backpackers use many kinds of cutting gadgets, including survival knives, multi-tools, and razor blades. For many years, I’ve carried the Victorinox Swiss Army Knife Classic, but most of the time, I just use the scissors on that little multi-tool. So why carry the rest of the knife? After asking on BPL, I found several others using “backpacking scissors.” I’ll compare ten pairs of scissors to the Classic, using a baker’s dozen of backpacking-based scenarios and tests. The Classic was tough to beat. But you can save half an ounce (15 grams) by switching to a very familiar pair of scissors with a couple of tradeoffs. |

USGS Science in Point Reyes National Seashore, USGS, December 2016, video
The park also uses USGS science to manage this iconic but complex setting. For example, local ranchers lease 28,000 acres of National Park land for dairy and beef cattle. To monitor ranch lands, the park uses maps, air photos and other databases from USGS. |

Condors in Purgatory, Science Notes, August 2015, multimedia
Swooping low across a canyon inside Pinnacles National Park, California condor #444 appeared to be in fine health. “Ventana” hatched in 2007 from a nest in Big Sur, and she paired five years later with #340. The next year they fed their first chick regurgitated food scavenged from miles away. That food came from a dead animal—rotting, stinking and crawling with maggots. But one of the condor’s favorite meals, the gut pile left behind after a hunter kills a deer or wild pig, threatens the survival of this critically endangered species. |
