Tactical Actions of the Team

The team's tactical actions were based on:

• available information about the routes (reports, photos, etc.);
• ensuring safety;
• experience in wall climbing. The Leningrad team has been gathering information about the Erydag massif since 1980. Therefore, based on the available materials, observations of the wall during previous visits to the area, and experience climbing on this wall, a tactical plan for the ascent was developed (see sheet 6), which was fully executed during the ascent.
• On August 3, 1987, at 5:00, the team, after preliminary processing of the first two ropes the day before, started on the route. Tsaruk works first. The other participants move along the fixed ropes.
• In a day, 16 ropes were passed and one processed.
• Overnight stay — comfortable, lying down, in a grotto (point 8), as planned according to the tactical plan.
• On August 4, 1987, they started work at 7:00. Pasikhin works first.
