- A documentary film about five members of the Cornell Tree Climbing Institute who traveled to Whitaker Forest to collaborate with University of California at Berkeley's Center for Forestry. The object of the trip was to collect of Giant Sequoia seed cone for research purposes at UCB.
looks like climbing with that footstrap is harder than footlocking... Even with switching feet from time to time, it just makes sense that using both feet together is going to be easier on the body.. Nice video.. would have liked to see some actual footage of the cones getting picked and bagged
@markstevenbuisness The rope is pulled over the limb and tied into a circle, with both ends on the ground. To get the rope down, we simply untie and pull it back over the limb or through the anchor.
i second that i would love to come climb these too
Im only beginning but I just tried using two footloops hooked up to a petzl ascension. Amazing compared to just the one leg working..
Really cool video!!! Thanks!
This is the way I learned to do amateur aid climbing decades ago. I notice that now many professional arborists have transitioned to a single 'rope walking' technique, because most of the work is done by both lower limbs and it causes less strain on the back because they stand vertically while ascending. There is some additional investment in gear, and they still seem to use a dual technique when moving through the canopy after getting up. In a 300 foot tree, anything that reduces work to get up there must be worth considering....
Oh, yeah...I definitely use a rope walker system. Some of the younger instructors have energy to burn, so they can still Texas Kick their way up!
@CornellTreeClimbing could you do a video on this? and other carious ways of attaching your ropes and retrieving them.
We try to limit our impact as much as possible. All rope turn around points are protected, as is fairly typical of tree climbing practices. Root compaction isn't an issue.
@murphy4trees I don't know of anyone foot locking on this type of long climb. I'm not very good at it, but there are those on our staff who do it well. Others use a frog-type system with two foot straps. I'll check to see if we have any footage of the actual collecting.
@petzltreeclimber Yes, an autoblock on my leg loop. Although, with 300 feet of rope below, I could have just let go and hung there with the weight of the rope locking of the device!
@joshuarugg That is quite true. We'll probably use a variety of methods this year. Everyone has their favorite.
@markstevenbuisness Sure - you might check out the Getting the rope in the Tree, I think it is also up on our page. There is another video on ascending using the full circle that might be of interest. Check out our web page for additional videos. Feel free to send questions our way.
How do you remove your rope from the tree? or in other words what knot do you tie to make the rope removable?
More balls than I. I live in Florida and do tree work for a living and I'm skiddish going up into pines that are at best 120 feet tall..LOL. They're 150 foot OVER the tops of trees that are probably that high from the getgo..
wait you guys are close to itchica new york? my whole family is from upstate! dude thats a beautiful place!! :)
The seed.. its so small! its unreal!
Indeed. It is striking how much potential there is in tiny little things.
at 8;09 do u have your atc backed up by a prussik or friction hitch?
@CornellTreeClimbing oh i have never had to deal with that cuz i am 13 and i only climb to like 50 ft but i hope to go higher
WOW!!!!
something I would never experience, because I'm afraid of heights.
@CornellTreeClimbing id love to tag along one of these days. im an arborist climber from hawaii. maybe plan another climb sometime in 2013 and ill come along :)
@dottydog2 about 35 liters
rope walker with a pantin would have been much faster and more energy efficient.
first
