Many of the regulars on this Board know I created a map of the 97 switchbacks a number of years ago. The map in Excel format, with all of the data used in creating the map, can be seen
HERE. Thanks to BobR for his excellent consultation and making it available to everyone.
A jpeg version of the map can be seen
HERE without the backup data.
Well, since I just learned how to label photos this past month (you can view my latest Lone Pine pano with peak labels
HERE, I decided to label all of the switchbacks in a photo BobR shared with me some years back. It is the best photo I have ever seen of the switchbacks, taken from the notch south of Mt. Muir's summit near the trail switchback.
You can see the full version
HERE.
The first seven switchbacks are hidden below the ridge between Trail Camp and switchback #8. Switchbacks #11 to #14 are not discernable, and switchbacks #37 to #41 are too close and lap over the ridgeline to be discernable.
One interesting thing to note is that an old switchback was rerouted many years ago. The v-cut can be seen to the right of switchback #92. Back then, before the current switchbacks #93 and #94 were made, there were only 95 switchbacks.
Were there ever exactly 99 switchbacks? That seems to be an enigma no one on this Board has been able to shed light on. One thing is for sure, Mount Whitney undergoes constant change, so it is just a matter of time(hope a long time!) before some part of the switchbacks will collapse and have to be rerouted.
