Marie and I hiked Emerald Mountain today. It's a 5 mile round trip with a 1,400 ft vertical rise, so it provided a very good two hour workout. Here's the route.
Emerald Mountain is directly across the valley from the ski mountain, so this is the view half way up.
And this is the view from the top!
There's also a great view from the top of the Flattops to the south.
