let's continue the spot the location game :-)
first image - Sunrise High Sierra Camp, right on the Meadow below, walking towards Cathedral Pass
second - tent set up just before crossing the water below Mount Lyell. JMT goes up the ridge right above your tent.
three - Donohue Pass, looking west-ish.
four - hmmm dunno. Peaks look like northern half of the trail, probably a part I rarely hike on (Reds Meadow to Silver Pass)
five - same as above
six - hard to tell, but since it seems in order north-south, I'd say south side of Silver Pass, just as you get to the section before the steep climb up the left side of the valley before you reach a plateau well above treeline
Seven - one of those Indian-named lakes below Silver Pass, north slope.
Eight - Marie Lake, West Shore looking east
Nine - probably same place looking north east
10 - dunno where exactly, but based on before and after pix, it's either near Muir Trail Ranch or in Goddard Canyon below Evolution Valley.
11 - looking back towards Piute Creek from the steep climb into Evolution Valley
12 - Wanda Lake shoreline - looking back to where you came from
13 Muir Pass Hut
14 - south of Muir Pass, Black Giant cut off on the left image edge
15 just below Helen Lake in Le Conte Canyon
16 lower in Le Conte - but still well above the Meadows. Dusy Basin trail goes up the valley left in the sun.
17 close to Little Pete Meadow
18 peaks west of Le Conte, same range Black Giant is in off the image on the right.
19 just below Mather Pass looking at the Palisades
20 just of Mather, entering the level section in Upper Basin
21 - looks like glacier moraine and some wood - probably a camp site real close to the trail, right side, with water about 200 feet to your west. Been there myself :)
22 - same place looking east at the end of the day
23, 24 - one of the lakes below Pinchot north slope
25 near Pinchot Pass, but not the actual pass.
26 one of the Lakes below Glen Pass
27 - Painted Lady above Rae Lakes
28 - the small lake below Forester Pass just as the trail does a 180 degree U-turn to head out to the exposed ridge area further north before turning back towards Forester
30 some lake between Crabtree and base of Whitney, reflection could be Mount Hitchcock.
