Lost delicate gold heart pendant necklace near a picnic table on a hiking trail by Deep Creek Lake in Western Maryland.

I lost a delicate gold heart pendant necklace while hiking near Deep Creek Lake in Western Maryland last weekend. It was a gift from my grandmother, and I remember taking it off to apply some sunscreen. I think I may have left it on a picnic table near the trail. I'm really hoping someone might have found it and can help me retrieve it. Thank you!
