You can "go to ground" with a Clark as an oversized sized bivvy bag; best to use a ground sheet. It's got stake out loops for the sides near the ends. The head and foot hoods for the bug net and weathershield are rigged with guy lines over trekking poles or sticks along with the tarp instead of using the little pole hoops. But it's nowhere near as comfortable used as a ground bivvy. The Clark is quite a clever (cool but a bit spendy) shelter system.
