You just found a disk lying in the brush, there's a name and phone number written on the back.
Keep in mind you just shanked your driver into 5ft on untamed and overgrown forest

Do you put it in the return box at the park entrance and/or contact the owner.
Or...
Claim it as your own and play on(I mean they obviously weren't looking very hard if they couldn't find it right?)
