Bears Aren’t “Curious” About Your Tent-They’re Tracking Calories A bear that wanders into camp at night isn’t looking for conversation. It’s doing what it’s built to do: find dense calories with minimal risk. If it gets rewarded once-an unattended cooler at a car camp, a snack bag left in a

Altitude sickness is a planning problem, not bad luck Altitude illness usually shows up like a minor nuisance: a dull headache, a little nausea, a hiker who’s suddenly quiet. In the mountains, small problems don’t stay small if you keep climbing. From a military perspective, this is a preventable casualty

Heat Illness Is a Performance Failure First, a Medical Emergency Second Heat illness usually starts as a small drop in output: slower pace, more breaks, and sloppy decisions. In the military, we treated that as a warning light, not laziness. If you ignore it, you don’t just risk discomfort. You

Snow as a Building Material: Strength, Sintering, and Load Paths Why snow shelters fail in the real world Snow shelters usually fail for boring reasons, not dramatic ones. The roof gets too thin, the shape is wrong, or someone keeps “touching up” the ceiling until it turns into a weak

Night camp control starts before darkness and before stress A controlled night camp isn’t about turning your campsite into a fortress.

Avalanche terrain basics that hikers and snowshoers routinely miss Avalanche terrain is not a “mountaineers only” problem. If you hike or snowshoe in winter, you’re in the same physics as everyone else: snow on a slope, plus a trigger, plus a weak layer, equals motion. The reason hikers get hurt

Scree, Talus, and Rockfall: What You’re Actually Walking On Loose terrain is one of those hazards that feels “optional” until it isn’t. One minute you’re on a normal trail, and the next you’re on ball-bearing gravel, a ridge of shifting blocks, or a gully that funnels rockfall like a bowling

Temperature Reality Check: Why “Warm Enough” Sleep Systems Fail in the 20s Cold-weather sleep systems fail for predictable reasons. It’s rarely because you didn’t buy an expensive enough bag.
