Dirty Wounds, Smart Decisions: Preventing Infection in Wilderness Wound Care
Cuts and lacerations are among the most common injuries encountered in the backcountry, but in wilderness medicine the greatest threat often isn’t the wound itself—it’s infection. In this episode of the AWLS Wilderness Medicine Podcast, we explore why nearly every wilderness wound should be considered contaminated and why thorough irrigation and cleaning are often far more important than closing the skin. Through real-world wilderness cases, listeners will learn when wounds should be left open, why premature suturing can trap bacteria and lead to serious infections, and how proper wound care can make the difference between an uncomplicated recovery and a medical evacuation. Whether you’re a backpacker, climber, guide, first responder, or wilderness medicine provider, this episode offers practical, evidence-based principles for managing wounds safely when definitive medical care may be hours or days away.

Altitude Illness and Rescue on Aconcagua
Join mountain medicine expert Dr. Sebastián Donato for a fascinating discussion on the realities of altitude illness on Aconcagua, the highest mountain in Western and Southern Hemispheres. Drawing from recent rescue operations and real patient cases, Dr. Donato explores the recognition, prevention, and treatment of acute mountain sickness (AMS), high-altitude pulmonary edema (HAPE), and high-altitude cerebral edema (HACE). Through dramatic stories of climbers who required emergency evacuations, listeners will gain valuable insights into the challenges faced by rescuers and medical teams operating in one of the world’s most demanding high-altitude environments. Recent data from Aconcagua show that altitude illness accounts for the majority of mountain evacuations, with HAPE being the single most common reason climbers require rescue.

Canyoning Considerations: Beauty, Adventure, and Hidden Hazards
Canyoning combines hiking, climbing, rappelling, swimming, and navigating through narrow canyons carved by water, creating one of the most exciting adventure sports in the outdoors. However, the same features that make canyoning thrilling also create significant risks. Participants may face foot entrapment in fast-moving water, where a trapped foot can lead to drowning. Rope-related incidents, including improper rigging, equipment failure, and rappelling errors, can result in serious injury or death. Powerful waterfalls and recirculating pools, often called “hydraulics” or “keepers,” can trap swimmers underwater. Cold water exposure and prolonged immersion can lead to hypothermia, even in warm weather. Wet suits are essential, but have hidden dangers. Flash floods, falling rocks, slippery surfaces, exhaustion, and limited access to emergency rescue further increase the danger. In this fascinating episode, Dr. Benny Chen explores the unique hazards of canyoning and the essential skills, preparation, and decision-making required to safely enjoy this challenging sport.

Where the Ticks Overlap
As climate and ecological conditions shift across the United States, the geographic boundaries of several tick species are expanding—and with them comes growing confusion about the diseases they carry. In this episode, we explore the spread of the Lone Star tick (Amblyomma americanum) and the blacklegged tick (Ixodes scapularis), and how their overlapping ranges are complicating the diagnosis of tick-borne illnesses. One of the biggest challenges is distinguishing between Lyme disease and STARI (Southern Tick–Associated Rash Illness). Both conditions can present with a similar bull’s-eye rash and early flu-like symptoms, yet they are caused by different organisms and may require different approaches to diagnosis and treatment. Join us as we examine how shifting tick habitats, changing ecosystems, and evolving patterns of human exposure are reshaping what we thought we knew about tick-borne disease risk.

Pulse Oximeters in the Backcountry
In the backcountry, decisions matter. And sometimes the only difference between a good outcome and a bad one is knowing when to stop, when to descend, and when to listen to what the body is telling you. In this podcast we talk about a small device that’s making its way into more packs, first-aid kits, and expedition gear — the pulse oximeter. You’ve probably seen one in a hospital or clinic. But what does it really tell you when you’re miles from a trailhead, at altitude, in the cold, and far from help? In this episode, we break down how pulse oximeters actually work, how reliable they are in the wild, and how they should, and should not be used in real backcountry and wilderness medicine settings. Because in remote environments, technology doesn’t keep you safe - judgment does.

Bats in the Grand Canyon
Bats are an essential—and often misunderstood—part of the Grand Canyon ecosystem. In this episode, we explore the role bats play in the canyon, why they are so abundant along the Colorado River, and what that means for people camping overnight in one of America’s most iconic landscapes. We’ll discuss the real but often low-probability dangers associated with bats, including rabies exposure and accidental nighttime contact, and explain why sleeping in tents is one of the simplest and most effective ways to reduce risk while protecting wildlife. The episode also takes a closer look at white-nose syndrome, a devastating fungal disease threatening bat populations across North America, and how human behavior—from campsite choices to gear hygiene—can help limit its spread. Designed for river runners, backcountry travelers, and anyone curious about canyon wildlife, this podcast blends safety, conservation, and practical guidance for sharing the Grand Canyon responsibly after dark.
