…And then you drop things in it (Timber! part 3)

At last! The first part in this series described how to navigate and use tools in and around a tree. The second covered how to build a bed of branches — itself a kind of specialized tool for catching large tree sections. What's next?

Embrace the Rain

The sun shone as we found our way to the Treasure Island Music Festival shuttle buses, but dark clouds loomed in the distance. Soon enough, sun would give way to rain.

As we walked, I explained my perspective on biking in the rain — after a long enough ride, you end up wet regardless. Either with sweat, if you don a fully waterproof outfit, or with rain, if you don't. So eventually, it makes sense to focus on staying comfortable rather than staying dry. And it's a small mental switch, but once it happens, you feel like you can embrace the rain, instead of just hiding from it.

It's surprising how much your perception can change when you see something from a different perspective…

First, you make your bed… (Timber! part 2)

Part one of this series showed how Matt (the professional arborist in the picture) moved himself and his tools around the tree. Once he had the tools where they needed to be, it was time to put them to work: the next step was to trim the remaining branches, and to arrange them on the ground so as to create a reasonably soft drop zone for the logs that would eventually follow.

The process of trimming the branches (and dragging them into position) was straightforward, but included some unexpected nuances. Our standing orders were to never approach the tree until Matt gave the all-clear.

First things first, he would cut off a branch. Easy enough…

Timber! How to navigate a tree

Imagine you want to cut down a single, very tall tree. How does it work? How do you do it safely, without damaging surrounding trees, and in a way that allows the lumber to be put to use when all is said and done?

When the opportunity to witness just such an adventure came across my radar, I jumped on it. I've always enjoyed watching people work, and this was a great chance to see someone work in a way that was completely different from what I'm used to.

Mark (bottom, in the photo) owns land somewhere in the forests of the Santa Cruz mountains. As part of a road rerouting project, he brought in his friend Matthew (top; a professional arborist) to cut down what we would later discover to be a 200-foot-tall Redwood tree. Mark mentioned that he plans to use his small sawmill to mill the logs from the tree into lumber, and to use the lumber to build a deck for a house overlooking the site.
As with a lot of work projects, the most important aspects of a job like this are tools and infrastructure. You have to be able to move around, you have to be able to move your tools around, and you have to be able to put those tools to use.

In the photo, Matthew continues climbing after setting a rope 75 feet above the ground. The rope gave him a handy re-belay (aka rope transfer) point, in case his fixed top rope ended up too short to reach all the way to the ground.
On previous days, Matthew had cleared out some of the lower-hanging limbs on the tree. This particular day, he would essentially climb the full tree twice. On his first pass up, he finished off the limb removal, followed by a lunch and rest break back at ground level. He rigged a 2-to-1 rope system for the top half of the descent/ascent — he would climb twice as much rope to travel a given distance, but he'd only need to use half as much force.

In the photo, he grabs his fixed top rope to keep track of it (and, presumably, to keep it from twisting around the tree) on his way down for lunchtime.
And what's lunchtime without some goofing off? Matthew told us that this was the tallest tree he had ever climbed, and the effect of being the weight at the bottom of a 150+-foot pendulum was that he could practically fly by pushing gently off of the trunk.
And as he sat down for some food and rest, some of the kids took turns on the rope as well.
After lunch, Matthew gave us a short course on chainsaw safety: how to hold it, how to start it, how the safety mechanisms worked, and what to wear to keep safe while using it. Then he cut down a short tree to demonstrate, at ground level, the hinge cutting technique that he'd be using to cut down sections of the actual trunk.

Once that tree was cleared out of the way, he grabbed his gear and started his second climb, this time using a variety of rope ascent devices that made the job more efficient than the first climb.
Finally, once he was situated near the top of the tree again, he dropped a rope and had us attach his saw. Time to move the tools into position and get to work…
