Thankfully there were minimal health issues and everyone returned today healthy but smelly and sandy after three days without washing (and in some cases without changing clothing).
I really enjoyed the trip since my role gave me the chance to see a lot more of the desert than I did last year when I was hiking with just one group. This year I was with the expedition leader Mahmoud, and we drove between the groups in his 4WD.
Mahmoud is an interesting guy who is passionate about the desert and spends his time alternating between running a company that leads deep desert expiditions (often for groups of scientists studying geology or neolithic artifacts) and volunteering with the Egyptian government in various environmental projects.
I was lucky in that I got to cover a lot of ground between the six groups and so see many differnt faces of this part of the dessert: Sandy flats with grassy outcrops and multitudes of animal tracks, monumental limestone formations whittled by the wind and sand, valleys of small stone domes, sand dunes, and a 400 year old mimosa tree flowering in the barren landscape.
