Lost: REI tent tarp at base of Double Cross JTREE 11/17

I was using my tent tarp as a rope tarp at base of double cross. Party after use apparently put there rope and tarp on top of mind and I totally forgot about it when we moved on to the next location. Went back later that day when it was already dark and it was gone. Found the party that was climbing and said they left it there. Anyone pick it up?

Grey tarp with the orange and black color coded loops at both ends. REI brand
