It might not be easy for someone to find a ranger to turn a found item in these days. If it was climbers who found it, there are not many public platforms/forums around, so I expect to see a shout out somewhere. I will keep an eye out and keep my ears open for you. If it was hikers who found it (they travel under Discovery Wall often), I don't know where they would turn to to make PSAs.
In any case, hope your wallet finds its way back to you via a chain of good samaritans.
