Last spring, I took a 30-foot fall on the second pitch of a 3-pitch 5.7 trad route in Sedona's Coconino National Forest, and it had nothing to do with my climbing ability. I'd placed a #3 cam in a wide, flaring crack, tugged it once to test, and started pulling up to clip my next piece of pro when the entire 18-inch section of sandstone I was standing on sheared off like a cookie crumb. I free-fell 12 feet before my #4 cam placed 5 feet below held. I finished the route, but spent 20 minutes picking 3 pounds of loose rock out of my harness and my belayer's hair, and he had to get 3 stitches in his forehead from a flying block.
I'd spent 5 years leading trad on Yosemite granite and the Gunks, and I'd never encountered anything like it. The Southwest's loose sedimentary rock---Coconino sandstone in Sedona and Red Rock, Entrada sandstone in Indian Creek, limestone in Joshua Tree, Navajo sandstone in Zion---doesn't behave like the solid, crystalline rock most trad climbers learn on. Pro placements that feel bomber in granite can blow out with a single hard pull, route-finding is a constant gamble between solid rock and waist-deep choss, and a single misstep can send house-sized blocks tumbling down the route for hundreds of feet.
If you're planning your first multi-pitch trad trip to the Southwest, standard trad training won't cut it. You don't need to be a 5.11 climber to pull these routes---most of the best multi-pitch lines here are 5.6 to 5.9---but you do need to train specifically for the unique quirks of loose sedimentary rock, or you'll spend more time picking rock out of your teeth than sending routes.
Master Loose Rock Pro Placement Before You Touch a Route
The biggest mistake I see visiting climbers make is treating Southwest rock like granite: slamming a cam in any crack that looks wide enough, giving it one quick tug, and calling it good. In weathered sedimentary rock, that's a recipe for a blown placement and a long fall. Unlike crystalline rock, which is solid all the way through, Southwest sandstone and limestone have a thin, hard outer layer of desert varnish (that dark, shiny patina on the rock surface) over a soft, crumbly inner core that shatters under impact.
To train for this:
- Spend 2 to 3 hours per session at a local sedimentary crag (or even a road cut with loose sandstone/limestone) placing and testing pro without climbing . Bring your full rack, including micro-nuts, tricams, and small cams, and load each placement with as much body weight as you can, not just a quick tug. Test cams slightly under-cammed to avoid blowing out the soft varnish layer, and prioritize passive pro (nuts, tricams) over cams in flared, irregular cracks---they exert less outward force and hold far better in crumbly rock.
- Rub desert sand on your hands during placement drills to get used to the slippery, gritty feel of placing pro on real Southwest rock, where dust coats every surface.
- Practice back-cleaning: if you placed a piece of pro 10+ feet below you, and the rock between you and the placement is loose or fracturing, take it out and re-place it higher. If you fall, loose rock between you and your pro will shatter and eliminate the piece's holding power.
- Never place pro in a crack with visible loose debris inside it: chip away only already detached, loose rock to reach the solid varnished layer, and never damage intact rock to make a placement fit---Leave No Trace rules apply even on remote desert routes.
Ditch the Hangboard: Train for the Actual Demands of Southwest Climbing
Most trad climbers over-prioritize hangboard work and campus boarding for multi-pitch trips, but those skills translate almost nothing to loose sedimentary rock routes. These routes demand far more core strength, smearing ability, and approach endurance than raw grip power, so adjust your training accordingly:
- Skip overhanging gym bouldering, and focus 80% of your bouldering time on low-angle, slabby problems with minimal positive edges. Practice keeping your weight centered over your feet, using open-hand smearing instead of crimping, and engaging your core to stay pressed to the wall---this is exactly the movement you'll use on 70% of Southwest multi-pitch routes, where polished, sand-smoothed rock offers almost no handholds.
- Do "choss climbing" drills twice a week: head to a local crag with loose rock, and climb a moderate route while placing a piece of pro every 10 to 15 feet, no hangdogging allowed. Move slowly, test every foothold before you weight it, and practice shifting your weight to avoid putting force on loose sections. This builds the specific, steady endurance you need for 5 to 8 hour multi-pitch days, where you're not cranking hard cruxes but moving continuously over broken rock.
- Train with a heavy pack: Southwest approaches are almost always 2+ miles of soft desert sand, and you'll be carrying 30+ pounds of gear, water, and food. Add 25 to 30 pounds to your pack for weekly 3 to 6 mile hikes to build the leg and core stamina you need to avoid being gassed before you even start the first pitch.
- Skip the chalk: sandstone gets so dusty that chalk will just turn into a paste on your hands within 10 minutes of climbing. Train to climb without chalk to get used to managing sweaty, sandy hands on smears and small edges.
Multi-Pitch Specific Prep for Unpredictable Terrain
Loose sedimentary rock adds layers of risk that don't exist on solid rock multi-pitch routes, so your training needs to account for the unexpected:
- Prioritize route-finding drills over strength work. Most Southwest trad routes have no fixed bolts, and the obvious-looking line is often full of loose choss. Study topos and recent trip reports before your trip, and practice picking the most solid-looking line (usually following dark desert varnish streaks) even if it's a half-grade harder than the "easy" choss line next to it. On route, take extra time to scout the next 10 feet of climbing before you commit to a move---if a block wiggles when you touch it, find another line.
- Practice fast, low-stakes lead transitions. Rockfall is constant on Southwest routes, and you don't want to be fumbling with your harness or coiling rope on a loose belay ledge while blocks fall past your head. Drill swapping leads, building simple anchors, and coiling rope in under 2 minutes with your partner until it's second nature.
- Train for heat and dehydration. Summer afternoon temperatures in the Southwest hit 100°F regularly, and dehydration sets in 2x faster in dry desert air than in humid climates. Do back-to-back days of hiking or climbing with a full 3-liter water pack to build the stamina you need to stay focused for 8+ hour days, and practice recognizing early signs of heat exhaustion in yourself and your partner.
- Practice bailouts on loose rock. Most Southwest multi-pitch routes are 20+ miles from pavement, so if you have to abandon a route halfway up, you need to know how to build a safe anchor on loose rock (use slings around solid, varnished rock features instead of relying solely on crack placements) and rappel quickly with a heavy pack. Do 2 to 3 practice bailouts on local routes before your trip.
4-Week Training Plan for Your First Southwest Trad Trip
This plan is built for intermediate trad climbers who can lead 5.8 on solid rock and have done 2 to 3 short multi-pitch routes:
- Weeks 1--2 (Skill Focus): 2 days/week of 2-hour pro placement drills at a local loose rock crag, testing every placement with full body weight. 2 days/week of 1-hour slab bouldering sessions focused on smearing and core tension. 1 day/week of 3-mile hikes with a 25-pound pack.
- Week 3 (Endurance Focus): 2 days/week of choss climbing drills (place pro every 10 feet, no hangdogging) on 2-pitch local routes. 1 day/week of 1-hour slab bouldering. 1 day/week of 5-mile hikes with a 30-pound pack.
- Week 4 (Taper): 1 day of light pro placement drills, 1 day of easy bouldering, 2 days of light hiking, and 3 full days of rest before your trip.
The biggest myth about Southwest trad climbing is that you need to be strong to do it. Last month, I led The Crucible , a 5-pitch 5.8 trad route in Red Rock, with no falls and no major rockfall incidents. The hardest part wasn't the 5.8 offwidth pitch in the middle---it was the 30 minutes I spent testing every single cam and nut placement on the third pitch, which was full of crumbly, flaring cracks. My partner teased me for going slow, but halfway up the pitch, he knocked a 4-pound block off that would have smashed his belay stance if we'd taken the faster, more direct line.
Loose sedimentary rock routes reward patience, not power. If you train to prioritize solid placements over speed, skill over strength, and caution over ego, you'll find that the Southwest's unique, rugged terrain offers some of the most memorable multi-pitch trad climbing you'll ever do. Just don't forget your helmet, 4 liters of water, and a healthy respect for the fact that the rock under your feet can (and will) fall apart at any moment.
