The road out to the bear viewing area, goes on to re-enter BC. This road was in heavy use, back when the Granduc Copper Mine was working in that part of BC. One of our forum members, Murray, worked out there for sometime, before moving north to Carcross YT. As I understand, it was one of the largest copper deposits ever found in North America. They had a bad snow slide out there at the mining camp that killed over 20 workers as I remember. The mine operated for about 20 years and the ore concentrate was shipped out, by truck to Stewart and loaded on ships to be sent to the smelters. Not sure what is remaining of the mine, the buildings, etc. or if you can even access the area, as I am sure it is still considered to be a private mining claim. Perhaps Murray, (explorenorth.com) can share some light on this.
I personally have never driven out past the bear viewing area, as seeing glaciers in Alaska, is very common when flying throughout the state. To many people, such as the OP, glaciers are not something to be seen where you live, so easy to understand the desire to see and photograph.
