When you drive close to the Yukon and British Columbia border you end up going in and out of each province multiple times. If you drive from Haines Junction Yukon to Haines Alaska you go through a newer park in British Columbia called Tatshenshini-Alsek park.
This park is gorgeous - I loved it - mountains and few enough trees that you can actually see the mountains. There aren't any services or even a campground so very few people. It may be my favorite part of British Columbia.
Most of the photos are from this park. The last two photos where you can see water are from Haines Alaska.
