Meanings of natural hooking in anglès

Kevin led the first two pitches-thetwo most natural hooking pitches on the route.

So far, I was impressed with the quality of the route and the natural hooking involved.

The next pitch started with more natural hooking and some really spaced-out rivets-perhaps25 feet apart.

With a combination of difficult natural hooking and runout free climbing, we reached the bottom of the Heart Recess placing only a handful of bolts.
