Glacier National Park - West Tunnel

The video discusses the construction of a tunnel in 1926, highlighting the challenges faced using the technology of the time, such as dynamite and jackhammers. Work was halted due to harsh winter conditions and resumed in 1927. The tunnel features observation windows and a sidewalk, but caution is advised due to low visibility. Originally unlined, the tunnel was later reinforced to prevent damage from falling rocks and stabilize the structure.
