Frank Church Wilderness Area - 2.3 million acres. Together with the adjacent Gospel Hump Wilderness and surrounding unprotected roadless Forest Service land, it is the core of a 3.3 million acre roadless area. That's the size of Connecticut without a town, a house or a road through it.

There are wilderness areas out west larger than some eastern states. And I meat real wilderness - no towns, no settlements, no houses, no electricity, not even roads. If you want to disappear, take a few horses in to the Frank or the Bob and you will disappear.
