This map shows a hike I made in 1980, from Glacier Point to the top of Half Dome, and back. My companion was Mr. Doug Spinks. We did the trip in one day, over Labor Day weekend. The distance up was 11.2 miles, with 5,512' gain and 4,032' loss. We took a short cut back, covering 9.3 miles distance, 3,900' gain, and 5,360' loss. We both had pretty bad shin splints!

I may have slides of this hike, and will try and scan some for your viewing pleasure.
