So this is a 20 mile round trip hike? Maybe you should note that on the main description, since this is probably a one to two day trip. Also, add some more description. Have you hiked this mountain? The writing on the page could be beefed up a bit, although the basic information is there. This is on the way to being a great page, just needs some more detail.
Yes, it is a 20 mile roundtrip hike.
I have hiked "Window Peak".
I've mentioned the distance in the "Window Peak" Overview and added some more information.
Let me know specifically if there's anything else I should add.
