Honestly, the "nobody knew where they were" situation is one of the worst kinds of stress - it's not even full panic yet, just this awful limbo. Happened with my brother two winters ago. He lost track of time hiking with a buddy, phone on low power mode, no signal half the route. We had zero plan. After that talk we tried GEOfinder phone number geolocation both sides agreed, he didn't need to install anything. You just enter the number, it sends a discreet link, and you get a map location back. Consent-based, no drama. Now it's literally in our family group chat description as the "emergency fallback." Simple fix for a stressful gap.
