Thane Avalanche Prevention

The Alaska Department of Transportation and Public Facilities conducted avalanche hazard reduction on Thane road just outside of Juneau according to their Facebook page. This was done to avoid a larger, unexpected one happening at a later date. A specialized blaster dubbed Daisy Bell was used during the operation to protect highways in the states from avalanches in winter. The conical shaped blaster used is suspended on a long line about 100 feet beneath a helicopter. According to a DOT fact sheet, “it packs a powerful punch large enough for triggering avalanches using a mixture of hydrogen / oxygen gas”. This machine has been used since 2018 allowing the DOT to carry out controlled avalanches with more precision and at a relatively low cost.
