Official Expedition Narrative & Archival Record
By 1900, the 800-metre sheer limestone cliff of the Marmolada South Face (Parete d'Argento) was universally deemed the most daunting unclimbed wall in the Eastern Alps. Multiple parties had retreated in terror from its smooth, polished chimneys and sweeping slabs. Beatrice Tomasson, an intrepid British equestrian and climber based in the Dolomites, engaged the peerless Primiero guides Michele Bettega and Bortolo Zagonel to attempt the wall. Departing from the Ombretta pass on July 1, 1901, the three climbers breached the lower chimneys and navigated a labyrinth of 32 vertical pitches of compact limestone graded UIAA V. Bettega's flawless instinct for rock and Tomasson's remarkable endurance propelled the party upward through gathering mist and cold. Emerging onto the glaciated summit ridge near Punta Penia after sixteen hours of sustained climbing, they claimed one of the greatest first ascents in European mountaineering history, forever establishing female alpinists at the vanguard of extreme rock climbing.

Ascent Route & Topography

Marmolada South Face (Via Tomasson-Bettega-Zagonel)
The Via Tomasson-Bettega-Zagonel on the South Face of Marmolada (3,343 m) is revered as the Silver Wall (Parete d'Argento) masterwork. Opened on July 1, 1901, by British climber Beatrice Tomasson with legendary Primiero guides Michele Bettega and Bortolo Zagonel, the 800-metre route scales over thirty pitches of compact, polished limestone graded UIAA V, standing as one of the boldest pre-World War I ascents in Europe.
Target Objective Peak
Marmolada
Marmolada (3,343 m / 10,968 ft) is the highest peak in the Dolomites, celebrated as the Queen of the Dolomites. Presiding over the Trentino and Veneto regions of northern Italy, its glaciated northern slopes contrast dramatically with its formidable 800-metre south face (Parete d'Argento). First summited via the north side in 1864 by Paul Grohmann, the mountain later witnessed fierce high-altitude combat during World War I and legendary rock routes by BΓ©atrice Tomasson and Tita Piaz.
Featured Expedition Climber

Tita Piaz
Born on October 13, 1879, in Pera di Fassa in the Ladin-speaking heart of the Dolomites, Giovanni Battista 'Tita' Piaz began climbing the vertical spires of the Catinaccio (Rosengarten) as a teenager without formal instruction. Combining volcanic physical strength with a daring, theatrical charisma, Piaz became one of the most famous alpine guides of the Belle Γpoque. In 1898, at the age of nineteen, he climbed the Torre Delago solo, establishing his reputation for ice-cold nerve on vertical ground. Piaz perfected the art of the Seilquergang β throwing and tensioning ropes across chasms to traverse otherwise impassable blank slabs. In 1900, he made the audacious first ascent of the Punta Emma via the Piaz Crack (Fessura Piaz), an extreme vertical fissure that pushed the technical standards of free climbing to the limit. Piaz participated in the historic 1901 exploration of the 800-metre South Face of Marmolada, completed daring first ascents on the Vajolet Towers and Campanile di Val Montanaia, and climbed the south face of the Schiefe Turm. A passionate anti-fascist, Piaz suffered imprisonment during World War II for his outspoken defiance of Mussolini's regime. After the war, he was elected mayor of his beloved village of Pozza di Fassa. On August 6, 1948, the legendary climber survived a fall while bicycling near his home, but succumbed to head injuries at the age of sixty-eight.
