On Monday August 30, after summiting LaPlata, I left my pack by the trailhead on CO-82 accidentally and drove away. It was about 2:00 PM. There was a couple loading up their vehicle at the time (we met them on the trail), there was a woman behind us with two dogs, and there was another pair of male climbers who we had met at ~13,500 while we were on the way down. I don't believe that anyone else was on the trail that day. In the pack are a few items of extreme sentimental value. If you have any leads, please let me know. Thanks!!
