Lost silver ten-hole diatonic harmonica left on a rock near the picnic area on a hiking trail in High Rockies.

I lost my favorite harmonica while taking a break on a hiking trail near High Rockies. I remember pulling it out to play a tune for my friends, and I must have left it on a rock near the picnic area. It's a silver, ten-hole diatonic harmonica, and it has some sentimental value to me as it was a gift from my grandfather.
