The 1968 avalanche in Biały Jar reached a length of 650 meters and a width of up to 80 meters.
The cirque floor sits at an elevation of approximately 1,100 to 1,200 meters above sea level.
Biały Jar is classified as a 'nival' zone, where snow cover can persist well into the spring months.
The area serves as a habitat for relict plant species adapted to the harsh conditions of the Karkonosze ridge.
Geologically, the basin was formed through glacial erosion which deepened the existing river valley.
Biały Jar is a prominent glacial cirque located in the Karkonosze Mountains, situated between Kopa and Srebrny Grzbiet. It represents a classic example of an alpine-type valley carved by glaciers during the Pleistocene epoch. The area is characterized by steep, rocky slopes and a subalpine climate that supports unique vegetation. Historically, it was the site of a major avalanche in 1968 that resulted in 19 fatalities, marking it as the deadliest avalanche in Polish history. Today, it serves as a critical junction for high-altitude hiking trails within the Karkonosze National Park. The terrain features a significant elevation gain and is prone to rapid weather shifts common in the Sudetes range. Visitors access the cirque primarily via well-marked mountain paths leading toward the main ridge of the Karkonosze.
From the edge of the yellow trail looking down into the basin, capturing the steep amphitheater-like walls.
Bring a windproof, waterproof jacket regardless of the forecast, as weather changes abruptly on the ridges.
Use professional trekking footwear with high ankle support due to the rocky and uneven trail surfaces.
Check the Karkonosze National Park mountain rescue alerts for avalanche warnings before setting out in winter or early spring.
Attempting the ascent during high wind warnings or heavy fog, as trail markers can become obscured.
Trails through the higher parts of the cirque may be closed or diverted in winter due to avalanche risk.
Stay strictly on the designated marked trails to protect the fragile alpine ecosystem and avoid erosion.
