ASCENSO
Climb Volcán Lanín on real terrain. 3,776 meters. Every contour from satellite data.
The Route
Tromen ranger station to summit. 7 checkpoints. 2,576m of gain.
Register. Start the clock.
First shelter. Rest or push?
Base camp. Acclimatize for a permanent stamina buff — or keep moving.
Last shelter. Gear check before the exposed section.
The fork. Traverse left (longer, less wind) or straight up (shorter, brutal).
Whiteout incoming. Wait it out or push blind?
Volcán Lanín.
What You Face
Real Terrain
360x360 SRTM elevation grid at 30m resolution. The same dataset that generates jtreks maps and 3D-printed keyrings renders the game world.
Altitude
Stamina drains faster above 2,500m. At 3,500m you're moving at 30% with tunnel vision. Rest recovers — but costs time.
Weather
Wind above 3,000m pushes you sideways. Whiteout events near the summit drop visibility to 10 meters. Navigate by compass.
Decisions
Rest at the refugio or push through? Take the traverse or go direct up Espina de Pescado? Wait out the whiteout or push blind?
Same Data, Different Product
The SRTM elevation data that renders this game also powers the jtreks interactive maps and generates 3D-printed terrain keyrings. One dataset, three products.
SRTM DEM (30m resolution)
In Development
Ascenso is being built with Unreal Engine 5 on real elevation data from Volcán Lanín, Argentina. The terrain is ready. The route is mapped. The mountain is waiting.
