Under the last snowflakes of spring in the Jura, Vincent Defrasne leads a small group on a discovery of ski touring. A day punctuated by learning technical techniques, managing effort, and immersing themselves in the wild world of the Haut-Jura, equipped with equipment adapted to mountain conditions.
Spring initiation in the Haut-Jura
At the beginning of April, a few centimeters of snow Fresh snow has blanketed the Jura highlands. Temperatures range from freezing at night to relatively mild during the day. This is ideal weather for putting on touring skis and enjoying the last of the season's snow. Vincent Defrasne leads a small group of five people in the valleys and forests of the Haut-Jura, introducing them to the sport in stable, dry conditions typical of this early spring.
Early departure from Les Rousses
The meeting is at 7:30 a.m. at the Balancier parking lot in Les Rousses. The sky is clear, the stars are gradually disappearing before the first rays of dawn. The temperature is hovering around -2°C. Vincent Defrasne is already there, ready to lead the day. Julien arrives shortly after, accompanied by three other participants, all eager for this day of ski touring in the Haut-Jura.
Briefing and preparation
After a briefing on the route, snow conditions, and safety instructions, everyone proceeds to a thorough check of their equipment: checking the attachment of the skins at the front and back of the skis, adjusting the tightness of the boots in uphill mode, and testing the proper functioning of the DVA (Avalanche Victim Detector). Vincent reminds us of some fundamental principles: effort management, observation of the terrain, and the importance of staying together. He also emphasizes the importance of choosing the right technical clothing for ski touring, in particular a windproof and waterproof jacket, lightweight hardshell pants, and a base layer in technical merino wool.
First efforts in the forest
The snow, firm and even, makes it easy to progress along the trail that winds through the fir trees. The pace is steady. Vincent emphasizes an often-overlooked technical point: laying the skis flat. He explains that keeping the entire ski in contact with the snow maximizes grip on icy areas and conserves energy over time. He also recommends walking "low" on the legs to remain more stable and avoid unnecessary imbalances.
Crossing the Combe des Geais
As the forest thins, the Combe des Geais opens up to a cold light. The wind becomes more noticeable in open areas. Vincent takes the opportunity to demonstrate how to adjust his hardshell jacket and tighten layers to prevent heat loss. The group progresses in a spaced-out file, each finding their own rhythm, adapting the pace to the terrain.
Ascent of Crêt Pela
The climb to Crêt Pela (1,495 m) requires more technique. Conversions become essential for climbing the steeper slopes. Vincent demonstrates the technique: firmly plant the uphill pole, pivot quickly on the downhill ski, then calmly place the second uphill ski without rushing. He emphasizes always maintaining three solid points of contact on the ground during the maneuver to avoid falling.
Summit break
Arriving at the summit, the view stretches across the Jura valleys and, in the distance, the still-snow-capped Alps. The break is an opportunity for a quick snack and a gear check before the descent. Vincent reminds us that good nutrition and hydration management is essential, even in the cold, to maintain lucidity and reflexes on the descent.
Descent to Loge à Ponard
The descent along the south slope towards the Loge à Ponard refuge begins on hard snow and then becomes heavier towards the valley floor. Vincent advises staying flexible, cushioning the unevenness, and looking far ahead to anticipate changes in texture.
Crossing the forest
The course continues through the forest, where the slalom between the fir trees requires vigilance and rapid adaptation. A few minor falls serve as a reminder of the importance of keeping your arms active and adapting your speed to the reduced visibility.
Ascent to the Croix de la Serra
A short traverse leads back to the Petite Combe. Skins are put back on for a final climb to the Croix de la Serra. Everyone manages their effort steadily, with Vincent reminding us of the importance of maintaining a calm breathing rhythm and avoiding too many stops, which break the momentum of the climb.
Back to the Pendulum
The final descent, gentle and rolling, brings participants back to the Balancier parking lot. Faces are strained by the effort but lit up with satisfaction. A technical, fast-paced day rich in learning.
