# Passage of the Col de Triolet, and First Ascents of Mont Dolent, Aiguille de Trélatête, and Aiguille d’Argentière explained — Scrambles Amongst the Alps in the Years 1860–69

> Chapter companion for Scrambles Amongst the Alps in the Years 1860–69 by Edward Whymper.

## What happens

In 1864, Whymper recounts the inaccuracies in the mapping of the Mont Blanc chain, highlighting J. D. Forbes's earlier survey and Mr. Adams-Reilly's subsequent meticulous survey that corrected major errors, including the fictitious Pointe des Plines. The chapter describes the successful ascents of Mont Dolent, Aiguille de Trélatête, and Aiguille d’Argentière, with Reilly's perseverance and skill under harsh conditions. It also includes the passage of the Col de Triolet, encounters with a unique ice-arch, and a period of waiting in mist on Mont Suc.

## Key lines

> Nothing binds men so closely together as agreement in plans and desires.

Shared goals and plans create strong bonds between people.

_Opening quote from Cicero, setting the theme of collaboration._

> The map produced from this survey was worthy of its author; and subsequent explorers of the region he investigated have been able to detect only trivial inaccuracies in his work.

Forbes' map was highly accurate, with later explorers finding only minor errors.

_Praise for J. D. Forbes' survey of the Mer de Glace._

> The Pointe des Plines did not exist. We had ocular demonstration of the accuracy of his previous observations.

The fictitious Pointe des Plines was proven nonexistent, confirming Reilly's earlier deductions.

_Confirmation of Reilly's map corrections through direct observation._

> It was a triumph to Reilly.

The ascent was a great success for Reilly.

_Whymper's acknowledgment of Reilly's achievement on the Aiguille d'Argentière._
