Comments
Some brave soul walked in from the west end and took this picture. Considering the earth here is a dam with water waiting to break through again, this picture was pretty risky to take.
Here is some images of the eastern portal.
I hate to be picky but the original Cascade tunnels length is 13,758 feet and not 14,508. Since your picture was taken, the tunnel has suffered a roof collapse some 1000 feet from the west entrance just about 2 years ago. The forest service has closed off the entrace due to flash floods in the spring and this now prevents people from walking thru the tunnel. Enclosed is a couple of photos that I took last year and the last one in 2001. The last shot I took after me and a friend walked all the way from the east side to the west. Thanks.
You can still enter the east entrance and get in there pretty far before it starts to get wet (summer 2009).
Sadly this two and half mile long tunnel had its roof collapse by flash flood in June 2007.
