We reached Whitehorse on Monday. Whitehorse is the capital of the Yukon Territory, and a city of 25,000 people. It has many historic things to see here so we decided to stay over one day to see them. We started our day in Miles Canyon, thinking we would take a short hike to see the gorge of the Yukon River. In our initial view of the canyon we saw an interesting example of what is called columnar jointing. The lava walls look like bundles of straight posts. Above the walls is a suspension bridge which we crossed to start our hike.
