    Maybe some tree guy named Levi may recognize his wife from once upon a time in Prairie Creek redwood park.

    212 ft. Sequoiadendron outside indigenous range

    Just got some confirmation from scientists that 196 ft. was the tallest they heard of prior to this one. This tree is close enough that I could measure it every year to keep track of vertical growth rate.

    212 ft. Sequoiadendron outside indigenous range

    Recently, our son and his wife moved to a camp in southern Oregon. I noticed a large trunk, and realized it was a Sequoiadendron - cones, foliage, etc.. I went back to help sort an old wood pile, then afterward we measured the tree for fun. I was surprised to learn it was 212 feet tall. The...

    Spiral pruning?

    Are you talking about stubbing the ends of branches?

    Spiral pruning?

    To my mind, "spiral pruning" conveys the corkscrew shearing topiary like done to Alberta spruce, etc.. As for thinning, among the 30 articles and tests I covered via the ISA's website last winter, the information on record there noted that thinning did effectively reduce wind sail and can...

    Coast Redwoods 2015 & 2016

    You may find interest or amusement to go on Amazon or Youtube and search for adapters, like Nikon > to Canon ... or Contax / Yashica (C/Y) > to Canon ... or Leica R > to Nikon .. etc.. There's scores of twist on adapters, like the blue part on the lens I posted above. There are twist on...

    Coast Redwoods 2015 & 2016

    Every lens I used last week in the redwoods was an older lens. The tilt shift was an older design, although still the relatively recent "EF" mount still in use today. But I also adapted a 1970s FD 300mm lens for shots like the following. Very narrow depth of field regardless of the aperture. I...

    Coast Redwoods 2015 & 2016

    In a way, yes. It's more of lens that eliminates the need for correction. Some try to correct tilted building and trunk lines with software, but the computer correction tends to lose up to 1/2 the file and resolution, whereas the lens enables keeping the entire file. This lens is sometimes used...

    Enjoyed trying a newly purchased lens this last week in the redwoods, a Canon 45mm tilt shift.

    Brotherhood Tree old growth redwood climb

    Although a guess may be the only practical option, Trees of Mystery wrote "over 2000 years" at their website. Gauging by ring counts elsewhere and some research reports in nearby Redwood National Park, I think the 2000 year estimate is a very reasonable and close number.

    Brotherhood Tree old growth redwood climb

    I didn't watch or ask about everything they did, but a photo peeking into the canopy around 140 feet up shows them switching over to other ropes at that point. It's unique to watch from below because once they vanish into the canopy it reminds me of someone leaving orbit. The first time I met...

    Brotherhood Tree old growth redwood climb

    That's similar to why I look forward to my next drive there in a week or so, alone. I like going solo best sometimes so I can wander and relax in quiet spots.

    Here's some bits of video from the climb that I put on Youtube:

    Brotherhood Tree old growth redwood climb

    Hopefully .. and thank you. I've had some practice, but the camera and lenses I use also cost enough to help some. The man on the left is the French broadcasting interviewer just before touching ground an unharnessing. Among the rookies, he adapted pretty good, reaching the interview area about...
