Warming permafrost can cause massive steel ski towers to tilt and fail
As permafrost melts due to rising temperatures, the massive steel towers supporting alpine ski lifts are losing their structural foundations, causing them to tilt at dangerous angles.
Glacial engineering traditionally relies on steel anchors drilled up to 50 meters into permafrost maintained at -10 degrees Celsius. However, as these frozen foundations warm, the bonds melt and cause massive pylons to suffer tilts of 5 to 10 degrees.
