Specific Preparation
Research the route, including guidebook information, online resources, opinions from other climbers you know who have climbed the route, etc.
Regarding online resources, recognize:
“Eldo gear gets crowdsourced. Most of us would probably be a lot more conservative about whipping on the pins on, say, Naked Edge P4, or the Northcutt Start, if we didn't know that hundreds before us had already tried out the fall. A downside to this is that there are a lot of posts on MP that tend to downplay the seriousness of Eldo routes. Collectively this can create a mindset where people feel encouraged/subconsciously pressured to go for it perhaps more than they should.”
In addition, crowd-sourced information has no standard or consistency, so treat online resources as suspect.
Note any sections of the climb, anchors, protection, movement etc. that may be challenging or present difficulties.
Have a plan: what are your retreat options should weather or other factors demand you get off the cliff? What variations or other routes are nearby?
“Research. Obsession. Commitment. Focus. Preparation. None of these can be forgotten when playing a high stake game like rock climbing. Casual class 4 cruising can still result in death with a lapse in any of these items.”
Wear a helmet! “Without a helmet you don't even need to pull a hold or blow it. Someone above you could just as well drop a #3 and when you rip 80' even if the fixed gear your clipping doesn't rip there's still a good chance you'll take out another party.”
Technical Skills
“Become proficient in placing gear and building anchors before venturing on to climbs requiring these skills.”
Placing good gear requires considerable practice, as does developing an "eye" for gear placements and natural gear opportunities.
Practice and develop gear placements in a safe, ground-school setting. Aid climbing is a great way to learn what a good placement is, and how to remove gear. Do it on toprope, watch your eyes/face should a piece blow (wear goggles).
Don't skip protection placements when they are available.
Belaying and anchoring- anticipate the direction and severity of the forces should the leader fall, and how these will impact the integrity of your anchor and belay.
“Never pass up gear placements and try to get 2 pieces early off (of) every belay.”
“I try to avoid getting tunnel vision for gear placements - I think it can be really helpful to have a wide focus as good options are not always super obvious.”
“Using ancient pins as pro is my least favorite part of (E)ldo.” Whenever possible backup fixed protection.
“…if you are not competent at building anchors, you aren't qualified to lead a trad route, especially in Eldo.”
“Redundancy in all components of an anchor system. Always test/weight a new anchor system before freeing yourself from the previous one (such as when transferring from a rappel to an anchor or vice versa). Belayer should stand close to the base, in line with force from potential fall. Be aware of factor 2 situations and place gear early when leading off an anchor. Make sure you don't have dangling slings, gear, shoelaces, etc before starting a down climb. Always be on the lookout for loose rock, including sketchy holds and debris that can be dislodged by the rope.”
Lead Climbing Mindset
Lead climbing is when the climber is most at risk.
“Eldo is rarely a great place for most climbers to push one's grade.”
The acceptance of falling as a routine and common aspect of (sport) climbing is a dangerous mindset to have in traditional climbing areas like Eldo.
“(I) adopted the "leader shall never fall" attitude, and climb far below my physical limit there. I'm often asked "You haven't fallen on your gear yet ?!?!" to much surprise. I think this mentality is what leads to accidents - "if you aren't pushing, you aren't climbing.”
With all that said, there’s more to it:
“There are times climbing when you really just shouldn't fall. Even on sport routes. You need to learn when those times are and if you're feeling sketchy you need to learn when and how to back off. It is an under appreciated and often unknown skill. Especially to novice climbers.”
“It’s not about pushing vs. not pushing - it's about knowing when it's safe to push.”
“Your climbing ability is absolutely the most important piece of protection you own, but never climbing anything where you might fall doesn't make any sense (to me). I do agree that building a good base of climbing skill that allows you to only fall on gear in situations where you are in control of the gear quality, fall length, etc, is a fundamental part of building the trad climbing skillset. Learn to hangout, to downclimb, and to make mandatory, tenuous moves in high-consequence situations. Also learn to evaluate when gear is bomber, marginal, or garbage, and when it is appropriate to back up gear/build life nests.”
“The actual pulling part is only the half of it in trad climbing. In that sense, Eldo is, in fact, a great place to push one's technical skills and expand one's head game. However, it requires patience and preferably a mentor who is more skilled than you.”
“I've found it pretty helpful to approach climbs with fresh eyes as much as possible. In the case of Wind Ridge, I'm pretty happy building a hanging belay 10-15' below the nasty red ledge. Solid gear, lets me see my second as they ascend p2, and lets the belayer see the leader as they ascend p3. And maybe next time I'll try going up p2 and clambering around the funny overhang on p3 before setting a hanging belay.”
I will add that many guides belay on the ledge about 30 feet below the big walk off ledge, and then lead through the crux hueco flake for the next pitch.
“ ‘Discretion is the better part of valor.’ Be OK with backing off or not embarking on something difficult on a given day if your head isn't in the right space.”
“1) Never underestimate an Eldo climb or pitch, regardless of rating. 2) Always be willing to back off. Leave gear if you need to. Have this discussion with yourself before leaving the ground so that you are fully prepared and willing to leave some expensive equipment behind. Your health and life are irreplaceable, gear is easy to buy. 3) If you are unsure about a piece then DON'T keep climbing. The next piece may not be good either. "Don't build a house of cards". 4) Build gear "nests" when the opportunity presents itself. Place two or even three pieces from the same stance. 5) Practice down climbing. Don't just try til you fall. Back down, re-group, climb back up and suss the sequence again. Down climb again if needed.”
“For me, on trad climbing at/near my limit I try to follow the rule of "two bomber pieces between me and disaster." But this calculus can be a lot harder on some routes in Eldo because of the nature of the flared, intermittent cracks and thin, hollow flakes, the fixed gear that can be hard to assess, and the style of climbing. In a typical scenario you might have, say, an old pin, a good but small rp, and a weird flared cam in a slot, and any or all of these might be behind a flake that's a little thin for comfort. It just makes the "two bomber pieces" part of the analysis that much harder. That is where climbing conservatively, going up and down a few times from a decent stance until you're getting the technical move "wired" on the onsight, and as many have said, backing off (and maybe even TRing/headpointing), all come into play.gaining the Eldo experience necessary to be "safe" in Eldo.”
