In reply to Mick Ryan - Editor - UKC:
A very interesting article. Those were the days! I was also in the Dolies that summer - mainly in the Pala group.
Incidently, in the photos, I am sure the two unknown people are actually below the Vajolet Towers and Brian is about to climb on the FIRST Sella tower with the great Pordoi wall in the background.
The Fourth Sella Tower was rarely climbed in those days and even today it is quiet. However it is included in the latest Alpine Club Guidebook (Dolomites West and East) with two routes, the West Face Direct (V) and the more modern North Face (VI+) which is ideal in hot weather.
