7 Smells You Should NEVER Ignore in the Woods (A Ranger Explains)

📕 Stay Found, my field guide for anyone who heads outdoors: what to carry, what to leave on the kitchen table, and what to do in the first hour if somebody doesn't come back → https://stayfoundbook.com Seven smells in the woods, from a musky barnyard smell in elk country to rotten eggs on a mountain. Five of them tell you the truth about what is near. Two of them lie, and those two are the reason this list exists. I'm Cliff Hollis. Thirty-two seasons as a backcountry ranger in the mountain West, the last fifteen running search and rescue. Every case here comes from park, agency and investigation reports. HONEST OR LYING THE FIVE THAT TELL THE TRUTH 7. A musky barnyard smell in the fall What it is: a bull elk in rut. Yellowstone: at night, a woman walked between a bull and his cows, escaped over a fence and fell about 15 feet into a sinkhole. Rule: stay at least 25 yards from elk. 6. A stale pond smell on a moving river What it is: a dying bloom of cyanobacteria. Zion, July 4, 2020: a dog died within about an hour. Anatoxin topped 55 micrograms per liter against a threshold of 15. Rule: do not drink it, even through a filter, and keep your dog out. 5. Wood smoke with no campfire in sight What it is: a fire over the next ridge. McKinney Fire, Klamath National Forest, 2022: about 300 acres one evening, about 18,000 by morning. At least 60 Pacific Crest Trail hikers were bused out. Rule: leave immediately, even if it means leaving gear behind. 4. A clean, sharp smell high on a ridge What it is: ozone from a storm's electric charge. Grand Teton, Exum Ridge, 2003: one strike, one climber killed, five seriously hurt, eleven rangers flown in on a long line. Rule: smelling it up high means you are already late. Get off the ridge. 2. Rotting meat and ravens over the brush What it is: a carcass, maybe a bear's cache. Near West Yellowstone, 2021: a dead moose lay nearly buried within 50 yards of guide Carl Mock. Rule: stay away from carcasses. Bears mostly smell clean. What you smell is what they are eating. THE TWO THAT LIE 3. Stove fuel inside a shut tent The fuel smell is not the danger. Carbon monoxide has no smell at all. Denali, 14,200 feet, 2018: both climbers lived only because one stepped outside for air. Rule: no stove, heater, lantern or grill inside a tent. Opening the flaps is not enough. 1. Rotten eggs, then no smell at all Hydrogen sulfide shuts your nose off around 100 parts per million, and carbon dioxide never had a smell. Mammoth Mountain, California, April 2006: a snow cave over a gas vent gave way, and three men died. Rule: in thermal country, leave immediately if you feel sick. Rules differ by park and state, so check the local agency before you go. CHAPTERS 00:00 A fence under twenty feet of snow 00:53 7. A musky barnyard smell in the fall 03:14 6.
