63, that's High Lake
(Gmap4 map). NEW Army pass trail climbs the slope to the left of it. In fact, I can see two stretches of the trail on your full-size version of the picture. ...and it looks practically horizontal for a long way!
(Old) Army Pass tops out just beyond the top of that vertical cliff in the picture center. Cottonwood Lake 6 is just on the other side of the plateau with the cliff.
Edit: Looking at the map and then your picture, I think you tilted the camera just a little so the plateau looks horizontal. Actually, it climbs steadily to the right (east), as you can see from the contours on the map. And therefore, what appears to be a horizontal trail is actually ascending too.
Here's a picture I took from Trail Peak of the same area. Slightly different angle and much farther away.
