At the end of March and the beginning of April this year, I participated in
an expedition into the Southern Sahara. We visited the Libyan Desert Glass
area, saw rock engravings at the site of the legendary lost oasis of
Zerzera, marvelled at cave paintings at Wadi Sora and the Foggini-Mestekawi
cave in the Gilf Kebir, and examined the site of "The Largest Crater in the
Great Sahara", whose discovery was announced at the beginning of March.

All the while, I kept track of our travels using ded reckoning and fixed
the position of our camp sites using celestial navigation. If you are
interested in reading an account of this exercise in inland navigation
using a bubble sextant, I have posted it to the Pisces Press website at
http://www.pisces-press.com/C-Nav

There are a number of maps and photos, so even with broadband it will take
a couple of minutes to download.
