Standing on the top of Centre Pass. On the left side, you'll see the tip of Tripod Hill and in the foreground below it, the track.  That's where I came from, the valley in the right of the picture is the start of the Spey valley where I'm going.  The track is visible on the right side of the Spey.  The knobby hill on the right is the start of the ascent up Mt. Memphis, the summit of which isn't visible in the picture.
