Lost: McDonalds Chalk bag at JTree Lost horse wall

Lost horse wall right side.
Went up the wall before I realized I dropped the chalk bag. A group of very nice climbers found it and set it on a boulder near the base of dappled mare. After coming back after the climb, couldn't find it. If anyone's seen it - I'd be more than happy to provide some compensation. It's got some sentimental value.
