An unusual expedition to Kenya will feature a 19-day camping trip, visiting several well-known wilderness preserves. Throughout the expedition, a course in elementary navigation by the stars will be given. Because of Kenya's location on the equator, it is an ideal ''classroom'' in which to study the skies of both the Northern and Southern Hemispheres.
Around 300 BC the ancient Namoratunga people of Eastern Africa constructed a megalithic observatory. This was only discovered in 1977. At least 19 stone pillars were erected in such a way as to align with specific stars and constellations. These same stars and constellations are used by present-day Cushitic peoples to calculate an accurate calendar. The differences between ancient and prehistoric methods of astronomical observation will be studied.
Expeditions will depart on Jan. 15, 1983, June 23, 1983, and Jan. 2, 1984, each expedition lasting 19 days. The expedition size will vary from 8 to 14 members, plus a leader, an instructor, and a cook. The cost of $1,100 includes transportation by 4-wheel drive Mercedes-Benz truck; instructional materials; use of telescopes and sextants; all meals; camping equipment, including two-person tents and foam mattresses; and two nights in a hotel. Air fare is not included in the price.
