- Artificial High Directional Workshop
- AHDW Key Points
Recognizing the need for advanced-level train-the-trainer instruction on the use of any constructed frame or "artificial high directional" (AHD), RTR is now offering the 7 day ARTIFICIAL HIGH DIRECTIONAL WORKSHOP suitable for fire emergency and rope access professionals. From Reed Thorne, the co-designer of the Arizona Vortex, this AHDW is meant to assist the rope rescue instructor with information relative to the use of manufactured high directionals. This workshop would be suitable for ANY manufactured or improvised high directional (not including wood frame) including the Larkin Frame, SMC Terradaptor, or Ferno Aracnipod (students requesting training on these AHD are required to bring these devices with them to their program). This program concentrates on constructed frames in general and is not intended to teach highlines, advanced pulley systems, or offsets (although some of these are touched upon). Physics, as it relates to high directionals, is covered in an extensive manual and several lectures. The AHDW is a hands-on workshop on the use and correct implementation of artificial high directionals (AHD) for industry and wilderness settings. The AHDW is also well suited for teaching rope access professionals the benefits of constructed frames in their work.
BELOW: Two testimonials about the AHDW. One in South Australia (below) and one in Colorado.
The Fort Collins Fire Department had the great opportunity to assist with bringing Reed Thorne of Ropes That Rescue (RTR) out for a five day AHDW-5 class from November 16 through 20, 2020. The decision was made to bring RTR to Colorado because it was time for Colorado fire departments to discover the true and dynamic versatility of the Arizona Vortex which Reed Thorne helped design in Arizona, as well as discover the true ‘ART of Clean Rigging’ which RTR espouses.
The Ropes That Rescue Artificial High Directional Workshop is for those that have the desire to drive their AHD framing skills to the next level. Even during this class when you think you couldn’t go to higher levels of rigging, the curriculum takes you even farther.
As a spectator of the 2020 AHDW-5 class I got to sit back and witness the transformation of competency within the students. I watched how cultural norms shifted before my eyes. I watched a group of individuals become a team of rigging machines. I was so amazed with the level of competency that Reed Thorne was able to reach with 12 people in a 5 day period.
This class was not all advanced rope technicians and I had the opportunity to ask question of the students. I asked a student named Joey what he learned. The student literally looked at me and said,
“humility”, and then went on to say that he was amazed in what he learned, and what he didn’t know about this perfect devise called the Arizona Vortex, as well as how excited he was to keep learning more about it.
Joey was one of many student I got the opportunity to talk to after this class. The questions I would ask where, “what did you learn?”, “How did it change your ideas of fundamental rigging?”, “How much fun did you have?”.
Each answer I got was a lot like Joeys, but one of the student also talked to the transformation of their rigging fundamentals. Aaron said: “I always assumed rigging was rigging until this class, the intricacies that I learned in this class from small changes in just the way you should place carabiners into the AZORP head to the big picture of seeing full transitional, paradoxical luffing systems, rigging pods, and being able to actually picture them as Reed Thorne is explaining them.”
He continued “I suggest everyone wanting that next level to go to this class!! I want to go two or three more times.”
The only thing I can say as a person that is already bought into the curriculum is DO IT! This class is becoming a fundamental standard for our advanced rope technicians. We hope to continue the classes with greater and better venues in the future. Till then keep rigging, and a big thank you to Reed. You are a great resource to us all, and I hope to keep watching your symphony for many years to come.

More from "down under":
G'day Reed & Len, (NOTE: Len Batley is the Senior RTR Instructor in Australia. Read about "Lenny" HERE)
Thank you very much for a fantastic 7 days of advance rigging and building complex Artificial High Directional (AHD) configurations. I thoroughly enjoyed the course and it was an absolute honor to be part of the first Australian AHD Workshop and rig some Gucci setups with like-minded motivated people.
Now with a few days of reflection under my belt, including reading over my notes, looking at photos and allowing my brain to absorb the things learnt during the course, I can confidently say I have greater understanding of the Vortex’s capability and performance. Essentially, any set up with the Vortex is possible as long as the rules of physics are correctly applied. If anyone questions that statement, show them some of the configurations we rigged and dare them to say otherwise!
The highlights of the AHD Workshop that particularly stand out for me include the intensity of the rigging, guy plane considerations and jamb poles. If I had a preference, I would normally choose to rig in a wilderness setting over an industrial environment but the Old Royal Adelaide Hospital rigging was next level.
Prior to the AHD Workshop I had not been exposed to many jamb pole configurations and I feel the skills I have learnt and been exposed to on this course will better prepare me as a Rescue Officer for the Metropolitan Fire Service. ‘Knowledge doesn’t weigh very much and is hard to leave behind!’ Like all Ropes That Rescue courses I complete, my mind now wonders into the future possibilities in terms of application of the Vortex, trialling different concepts and of course aiming to continually get better at my craft and the art of clean rigging.
Returning to work I have completed several days of facilitating ‘plate spinner’ rope rescue training with the firefighters in Adelaide. Let me tell you it is harder to get excited about a tandem prusik belay than it is about doortex frame. In saying that a tandem prusik belay does still excite me!
For mine, the course was perfectly balanced between theory and practical elements. Reed, I commend you for the time and effort you have put into your Mac Keynote presentations. Graphics like the overlaying of a resultant force or a guy plane on an image cement the learning outcome you are explaining to the group and they look first class. Furthermore, the theory workbook is very detailed and I can only imagine the hours you have dedicated to developing it all.
I believe the discussion had by the class on day 3 when we set up the Easel A-Frame and modified the rigging for a ‘go’ or ‘no go’ was the perfect conduit between the theory and practical days. It really set the scene for bigger and better things.
Reed and Len, I want to send a big thank you once again for the time and effort you have invested into developing my rope rescue knowledge not only on this course but the past also. Your teaching styles accommodate each other perfectly to form a great instructor team. You both have incredible patience. Watching students fumble their way through rigging problems must be frustrating at times but we all have to start somewhere. As Reed said on day one “we are not born with the skill to rig. It is a learned behavior.”
Reed, I am sure you are aware, but if not, you have created quite a legacy in Australian rope rescue. Many people enroll in a Ropes That Rescue course to experience Reed Thorne in the flesh. I enjoy seeing how you go about your business and am thankful that you made the effort once again to travel down under to spread the Ropes That Rescue ethos to indoctrinate us into the rope rescue culture.You bring this incredible subject knowledge, infectious energy and amazing ability to communicate with passion in front of a class, even after being jet lagged. Your attention to detail is second to none and this is coupled with an amazing ability to conceptualize a AHD system prior to the first bit of rope being tied.
Len, it is nice to see the person who has had the most influence and mentored my rope rescue career working under/with their mentor. You have influenced many rope rescue personnel Australia wide and have a fantastic ability to explain Ropes That Rescue concepts while bringing an alternative way to look at the challenge ahead. I know your passion for rope rescue is to influence and educate emergency responders so thanks for sharing your knowledge with all. Thanks also for all the behind the scenes organizing you have done to make this course possible. Your networking in terms of securing locations to train is much appreciated. I now related the old Adelaide Dental Clinic as Jamb Pole Country! Please pass on another big thanks to Cathy for opening up your home, providing us all with an amazing feed and allowing us to talk rope rescue over several IPAs or a glass of South Oz Shiraz. Shit yeah!
A real testament to the Ropes That Rescue programs is that courses regularly sell out and yet there is no official nationally recognized qualification associated with them. That indicates to me that the personnel that enroll in these courses do so because they want to be challenged, better their skills and not just tick a training requirement box. Reed mentioned that he educates to the ‘highest’ common denominator rather than the typical fire service ‘lowest’ common denominator. That for me is exactly what I crave in a rescue course and has allowed me to network with others that feel the same. It is for this reason alone that I think the AHD Workshop could certainly be run in Australia again.
Thanks once again to all. Merry Christmas.

- Offset / Highline Rescue Workshop
- OHRW Key Points
For years, emergency rope rescuers and rope access technicians have asked for a training program on temporary rigging employing elevated rope tracking elements. The OFFSET / HIGHLINE RESCUE WORKSHOP is just the type of program where these elevated options can be explored in detail. The program looks at subtle, yet fundamental differences between the use of high angle offsets and drooping and/or reeving highlines for canyon/industrial locations where abundant high anchors are plentiful. Therefore, this is NOT a program that explores highly tensioned spanning elements (like the Kootenay Highline System) where high or full strength connections are mandated at either end, but rather only a look at other low tension highlines that can be used over gaps with higher anchorages. The OHRW is not an extensive highline workshop like the Advanced Skills Rescue Workshop (that program focuses on 100% highlines and the Kootenay Highline System).
The course begins with simple and easy to understand lessons on physics relative to ropes under tension used above the ground and how to keep spanning element anchoring forces low. The program moves between the subtle, yet substantial, differences between minor and major offsets and then moves into the distinctions between offsets and highlines. For rope access technicians, this course gives the student the groundwork for elevated transporting systems for men and/or materials used in work. The OHRW also has lectures on extensive pulley systems which are used to provide tension for these aerial rope highways. More than just a "highline" seminar, the OHRW provides a multiplicity of lower tension options for the rope rescue and rope access technician without the excessive training and discipline that a strict adherence to the Kootenay Highline System. Additionally, the program is taught in an environment conducive to this kind of discipline. This is NOT a rescue course only. While the techniques can be applied to rescue work and often are, these methods may be used in any rope access endeavor. The real difference is that when human loads are applied, secondary safety lines must be employed at all times throughout the process of movement.
- This program deals with a comparison between offsets and the use of low tension highlines for spaning canyons or industrial gaps
- Physics of rope rigging with emphasis on tension forces relative to tracking elements
- Acute differences between offsets and highlines (physics)
- Ideal for rope access technicians (those that work at elevation)
- Low tesnion highlines with higher side to side anchorages
- Anchor building - system anchors
- Knotcraft - basic through advanced
- Introduction to pulley systems (simple through complex)
- Moderate use of simpel to intermeidate frames (Arizona Vortex)
- Critical analysis of tracking elements-critical point test
- Major high angle offsetting:

- Deflection liness (belayed and self belayed)
- Two rope pendulum offsets (belayed from both sides)
- Limited highlines (only those with high anchorages and more than 15% sag) (NOTE: This is NOT a full highline program)
- Low tension reeving highlines (carriage belayed from both sides -reeve line belay options)
- Low tension drooping highlines (belayed from both sides)
Prerequisites: None. (Prior rope rigging experience strongly recommended)
- Personal Skills Rescue Workshop
- PSRW Key Points
The Personal Skills Rescue Workshop is considered by many past students as our most enjoyable, interactive and physically demanding. There is no shortage of "on-rope" time at this workshop! The PSRW, and the Team Skills Rescue Workshop are the courses which fulfill the 90% solution on most rope rescues within industry and wilderness locations. It is designed for the serious rope rescue practitioner wishing to improve their personal rigging skill and capability. This workshop is sometimes mistakenly perceived as a beginning program due to the personal nature of many of the evolutions. In fact, it is for those that never seem to get enough on rope experience or time over the edge. The PSRW begins with valuable, yet simple definitions for belays, self belays, conditional belays and conditional self belays and how these differ in their engineering. It goes into important orientation on personally carried gear such as ascenders and descenders, self belay devices, Purcell prusiks, the all valuable AZTEK kit and other items essential to safety in the vertical realm and then moves into practical and fun-filled days where multiple one-on-one rope stations keep the practitioner busy throughout the day.
Students in the PSRW practice their skills and learn to work together as a team in successful retrieval of this patient in a non-threatening environment. These are found in the Seven Minimalist Rescue Archetypes (7MRA) that lay a groundwork for understanding how solo versus semi-solo rescues vary in their risk to the rescuer. The PSRW goes well into often overlooked personal skills that are taken for granted on most rescue teams.
There is also considerable time spent on rope learning to climb/descend rope by multiple methods (even improvised if you drop your friction appliance). Passing knots, deviations, rebelays, rope to rope transfers, aid climbing and problem solving are all part of the PSRW. Proficiency through repetition to mastery are encouraged. There is a very very strong emphasis on advanced knotcraft in this workshop!

Speaking to a another RTR student—
"Like you, I was humbled that first day of the course. I had come in thinking I knew plenty of cool stuff. The next day I began to get a little of the (RTR) "lingo" going, and started to understand the diagrams, etc. By the end of the 7 days, I had expanded my rescue paradigm more than the complete decade preceding it. That experience was truly a watershed event in my rescue career. And I already knew more than anyone I worked with or for before I went to the class. So that speaks to Reed and his excellent program, but you already knew that.

- Team Skills Rescue Workshop
- TSRW Key Points
The Team Skills Rescue Workshop is ideal for industrial and wilderness rescue teams and is designed to begin where the Personal Skills Rescue Workshop leaves off and carry on into more demanding rescue practices and team-building skills. This, and the PSRW, are the seminars which fulfill the "90% solution" on most rope rescues within industry and wilderness locations. Lectures on intermediate physics and how it relates to rope rigging are common throughout the duration of this seminar. Emphasis is places on "why" we do something, rather than "how". Students, as a team unit, learn how to build seemingly complex arrangements for reaching, treating and extricating a patient from the vertical high angle environment whether in industrial locations or in the wilderness. All the while, emphasis is placed on building everything from the basic materials most teams will have along: rope, carabiners, pulleys, accessory cord, webbing and know how. Specialized equipment, while certainly handy and interesting, is discouraged in this rigging-intensive course. Some rescuers also feel that an intermediate-level program should include highlines. The TSRW includes an extensive lecture and practical section on alternatives to highlines in the form of "offsets". Ropes That Rescue has become known for its projection of these offsets as an alternative to training intensive highlines in the past 20 years. Offsets employ standard high angle techniques that most rescuers already know and so are more forgiving in the training curve than more elaborate systems.
The TSRW is not by any means a beginning rope rescue program. It is a serious venture and complete immersion into rescue systems that can sometimes be overwhelming to some less experienced practitioners.
"The Team Skills Rescue Workshop was enjoyably challenging. Too often, we teach our teams how to do something without teaching them why we do it a particular way. Reed spent a lot of time explaining the why behind the how. Without understanding the physics behind a procedure, most teams are unable to adapt their rigging to non-textbook rescue scenarios. If we were exposed to procedures in the seminar that differed from our SOPs, the instructors supported the RTR procedures with exceptionally sound mathematical and practical justification. Comparative analysis of various systems was enlightening.
RTR's abilities to tailor the training to a particular group was much appreciated. A team charged with backcountry rescue needs different training, equipment, procedures, etc., than an industrial rescue team. Reed seemed to have a genuine desire to show us ways we could decrease the amount of weight and bulk carried into the field without compromising system safety. Again, all his suggestions were supported with sound mathematical and practical justification. As a result, our team will be altering (and improving) some of it's rigging procedures."

- ASRW Key Points
ADVANCED SKILLS RESCUE WORKSHOP -
There are prerequisites for enrolling in this workshop. It is NOT entry-level. The Advanced Skills Rescue Workshop is held only one time during any given year (sometimes skipping a year) and is a seven day workshop dealing with the remaining "10% Solution". This rigorous course "for wizards" builds upon some aspects of the TSRW yet goes well beyond these both in intensity of rigging, and application of physical principles. The workshop begins on day one with an impromptu field exercise to assess existing skill level within the student "team". Emphasis is placed on low tech solutions to rescue scenarios before heading into technical solutions in the form of highlines. The workshop then explores all the available possibilities for setting up a horizontal, sloping or steep highline for removing, transporting or inserting rescuers or a patient. The ASRW is different from the Offset/Highline Rescue Workshop in that it is not 'entry level' (having no prerequisites) as highlines are greater than 150 degrees (much less sag) and following the Kootenay Highline System originally taught by Arnör Larson of the British Columbia Council of Technical Rescue (BCCTR). These are high tension highlines with very little sag and are ideal for rivers and places where high river bank anchors are not readily available. The ASRW also go into the many forms of reeving highlines including the English and Norwegian varieties and the discreet, subtle differences in the two. Single and double carriage litter rigging is covered along with passing both through an intermediary mid station on a long highline (called a "litter bypass"). Rule of Thumb techniques for determining the pre-tension on a single, twin or quadruple trackline highline are covered in detail if a strain gauge is not available. Use of a strain gauge (like the Rock Exotica Enforcer) is advantageous for keeping the highline within safety margins, especially when post-tensioning with a mass in the middle of the highline. Pilot line, messenger line and all forms of multiple delivery systems are explored in this workshop.
This is by no means an easy workshop. and it is certainly not for everyone. It has lots of carrying, walking or hiking, pulling and general work which must be accomplished by the students and so expect lots of physical exertion in carrying the many pilot lines, messenger lines and 1/2" diameter ropes and specialized, normally very heavy, hardware to the highline site. The ASRW is very "venue" dependent as to how long the highlines will be during any particular workshop. There may be, and often is, huge variation between wilderness locations and industrial ones.
In the end, there is really nothing like riding on a long highline. Even a short one by comparison. It can be quite thrilling to do so and students seem to enjoy the final reward that after all the hard work, they actually get to enjoy the technology in action.
