A small clarification (for Russell) not connected to the photo; I'm italian and in Italy Daniele is a male name.
A second note on the photo: my first impression was that the rocks were in the area showed golden in the aerial view, but my uncertainty convinced me to place the marker near the signal given by Google.

Close enough. How do you know a scale, to start with?

Also, I put a marker based on great trust in another hiker who has the location of the wings marked as 36°16’45” N, 108°14’14” W in his log book. A little further west than Daniele's point, but as she noted, finding things in the badlands from the sat-map is difficult at best

These are the "Stone Wings" formations in the Bisti Badlands of New Mexico, USA

I'm sorry, I never put the marker if my uncertainty is over 300 m (normally 200), but in this case the aerial view does not help and the error may exceed 1 km.
