Tina White approaching a typical rebelay from below in Kaninchenhöhle.
Note that there is little slack in the rope above the rebelay, though there
is no doubt that a lot will appear once the rope is loaded. This is something
to watch out for on the descent: when the slack disappears as the upper rope
is unloaded, it is possible to find that you can't remove your descender from
the rope without attaching an ascender to re-load it.
