    Trees from a distance

    That tree is on the Oregon State campus, i was helping their botany students and giving a lecture on tree ID.

    Trees from a distance

    Great job Green One. One of the largest ones i have seen in Oregon! It produces a ton of fruit, and it looks just like Kousa fruit.

    Trees from a distance

    All wrong, although one of you is in the right genus. Yes, it is a broad leaf evergreen. This tree is native to the lower elevations of the Himalayas

    none of those. and none even in the right family.

    Odd ball oak, prob a mutation

    Those are notoriously hard to graft. One of my favorite oaks, I would kill for a seedling of one. I have a client with one and it has produced acorns, but they all came out without the cut leaf.

    Dust masks for soil aeration?

    The biggest thing for controlling dust in air excavation operations is ensuring the soil is properly wet. If you are throwing dust, you will not be able to excavate deep enough or do the necessary decompaction work. One thing that I typically don't see people do is wear enough hearing...

    Fire tree

    and Luke Colvin helped out quite a bit as well, he ran our ground operation while Damien and I were in the tree.

    Fire tree

    There was not as much heat up there as some of the articles make it sound. But our rope choice was a poly/poly rope for the little extra heat resilience over nylon ropes. We did have a drone with an IR scanner to do a pre climb inspection before we even got to the site.

    Blue 32!

    Hey guys, i just looked at yale's website about the blue 32, turns out the published breaking is 6,000 lbs. I think Wesspur has a typo on their product page.

    Blue 32!

    It seems like its not a straight relationship like that, while in the same rope it does change like that but some ropes offer higher abrasion resistance through innovative constructions and materials in really small packages.

    Blue 32!

    We don't experience edges like they do in other rope disciplines, luckily trees grow relatively roundish. Edelrid has done some really interesting work on edge protection/ cut resistance. check out their series about it: https://edelrid.com/us-en/knowledge/knowledge-base/cut-resistance-of-ropes

    Blue 32!

    Yeah, measured from TIP. in a hard fall, it would be generation 200% in a base tie scenario. The numbers get messy really fast. and thats assuming no other factors like friction, tree structure, dynamic properties. Those terms do vary somewhat between manufactures, but not a ton. SWLL and...

    Blue 32!

    Yeah, thats why i listed it last. and it is a consideration for all ropes regardless of size.
