On Monday 5/2/22 at approximately 12pm I found a working iPhone laying flat on a rock close to the top of the 99 switchbacks. It had a few percentage points of battery left and looked as if someone took it out for a moment and left it there unintentionally. We charged it and tried to turn it on later but it’s in airplane mode and I can’t access any of the find my iPhone features. If you know who’s phone this is, please reply here or contact me via email at theodorechaas@gmail.com
