Gunks: Missing Gear (Black Diamond C4 0.5 with Petzl Ange S Biners and Mammut Contact Sling

I was climbing on Last Will Be First and High Exposure on Sunday 10/26 and I believe my partner forgot to clean a Black Diamond C4 0.5 likely attached to a draw made with Petzl Ange S carabiners in orange and silver with a Mammut Contact Dyneema sling.

If you happened to pick it up on either of those routes or find it somewhere, likely on or near High E, and have it in your heart to send it back to me, I will of course pay for shipping and a little extra for your trouble, I would be very grateful.

Thanks!
