Kalahaku Teeth to Waimalu Middle Ridge

A long journey up on one of Oahu's less traveled ridge lines.
After finishing all my KST sections, and having to bail from my KST traverse, I needed a new to-do list: Windward ridges. Still not clear to me from where to where people consider those ridges but looking at the old Ko'olau volcano's inner part, for me it looks like from Makapu'u to Kahana or Punalu'u Valley.
The Kalahaku Teeth was on my list for a long time, especially because it is right in my neighborhood. This ridge is North of Ahuimanu on the South side of Waihe'e Valley, Eleao Windward being on the North (another ridge on my list). It is considered an extreme hike, and you have to climb over 7 crumbly notches to advance to the top of the ridgA coupleple of weeks ago I was hiking with Krista, knowing that she was up there before I mentioned to her that it would be nice to organize a hike up the ridge.
She was in!
We got a good team of 6: Krista, Alex, Cisco, Steve, Oli, and Me.
The morning of the hike started with very cloudy weather, and of course, we started late too (wondering if Alex has something to do with that:). Thanks to Cisco's wife we got dropped off close to the "trailhead", where we had to be quick and quiet... After a short walk on an old road, we headed up the ridge and shortly reached our 1st peak Kalahaku (965ft). I am guessing that's how this ridge got his name?
Leaving the peak the trail started to get more overgrown, but still easy to navigate. Krista and Steve was the only one wly did this troute before, so they took over the lead when we approached the actual notches.
I stayed behind to take pictures of the group climbing up the tooth. Eventually, Krista had to put up a rope on e very slippery section, so everybody could pass faster and safer.
The next interesting spot was this narrow rock face which fortunately we didn't have to climb, so we just contoured around it. That's where we found probably the most difficult descent, where we had to put up a webbing to help us down.
After the descent, we never had to use our ropes anymore, but still had to push ourselves hard through overgrown areas.
The weather was holding up pretty well, but sometimes we got some drizzles over us. You don't want to climb those notches in rainy weather.
Krista suggested that everybody should walk together to make a more efficient uluhe bulldozing action.
At this point everybody started to struggle a bit, so we went from socializing and singing to huffing and puffing through UluHell. Everybody took his turn in pushing through the overgrowth, meantime the others could take it "easy".
And YES after 6.5 hours we arrived at Waimalu Meadows where of course the weather was nasty as usual, whiteout conditions, cold and windy.
So we just decided to head down to Waimalu Middle and stop later for a short break.
The trail was super nice and easy to walk on even with bad weather. But if you have never been up there or you don't have a topo map, the trail can get confusing and you may walk down on the wrong side ridge (like Alex did a couple of years ago :)
After descending for a while the weather started clearing up and we saw a couple of beautiful waterfalls on the side of Waiau ridge, so Oli just named them Waiau falls.
