Chimborazo, Ecuador - 1979

Our aim was the recently opened Refugio Edward Whymper (5000m) with access to the summit of Chimborazo (6310m) which was first climber by Whymper in 1880 (see Travel amongst the Great Andes of the Equator).

The summit at 1o south of the equator is the furthest point from the centre of the earth. Transport from Riobamba was by road with a struggle with scientific equipment on foot and mules for the last 200m above the snow line. Experiments included a randomised placebo controlled trial of acetazolamide in the prevention of acute mountain sickness, reactions times and the ability to excrete a water load (not the most popular test with the use of large quantities of chlorinated water). As a result of a chance encounter in Riobamba, and assistance with gastric surgery, we were awarded temporary, honorary Equadorian citizenship.
