Last August my friend and climbing partner Sam Miller and I went after the incredible Grand Teton Traverse.

Between the iconic skyline, Wyoming and Idaho’s beautiful scenery as the backdrop, and incredible climbing and scrambling, this is an all-time classic peak link-up that should be on any climber’s bucket list.

I had spent relatively little time in the Teton Range beyond climbing the Grand Teton itself. I had taken a few laps up classic routes like the Exum Ridge and Owen Spaulding.  I’d even had a chance to climb and ski the Ford-Stettner Couloir the season prior, but this would be my first time on any of the other features of the turreted skyline.

The Grand Traverse gets completed in a variety of timeframes, ranging from a few days to the current fastest known time of 6 hours 30 minutes 49 seconds, set by Nick Elson. I still enjoy hearing the tales of early quick ascents by Rolando “Rolo” Garibotti and Alex Lowe.

I wanted to share my gear list with many of you looking to add this objective to the adventure list this summer, or perhaps any time further down the road in your climbing career.

We all know gear needs and equipment will vary based on your style and anticipated time on route. Sam and I planned to do the entire Grand Traverse in under 24 hours. Some of our gear selection is indicative of the forecasted conditions and our competence (and confidence) in the given terrain. Your experience may vary, so please use this gear list (and any of my other suggested gear lists) at your own discretion.

As many of you now know, I try to steer away from creating these articles as full-length trip reports and to keep them relatively utilitarian. In full disclosure, we ended up descending from below Cloudveil peak, thus earning a Grand Traverse DNF in the process. That being said, the follwing gear list was near-perfect for us that day.

We cruised through the “meat” of the Grand Traverse known as the Cathedral Traverse. The Cathedral Traverse starts with a healthy serving of 6,000 feet of vertical gain for breakfast up Teewinot. The route then traverses over Mt. Owen and ascends the striking North Face of the Grand Teton, bringing you to the Lower Saddle. The climbing on the North Face is the technical crux of the route and presents the greatest route-finding challenges.

We climbed Teewinot quickly and navigated all the way to the base of the Grand without much issue. We ran into a few major snags on the Grand that were out of our control, but that should be expected on any alpine outing.

After making our way to the Lower Saddle, we refueled and continued on. Our greatest hang-ups came—surprisingly—on Middle Teton and the Ice Cream Cone.

We had focused so much on the Cathedral Traverse, as we had anticipated that portion to be the crux of the outing, that we got very off-route on Middle, South and Gilkey. Our lack of beta memorization, fatigue and low light compounded our challenges in this section; realizing that we were no longer on pace to finish in under 24 hours, we opted to descend down valley from underneath Cloudveil. We’ll just have to head back to finish it up another time!

Regardless of the final outcome, I was happy with the gear we wore and carried with us. Some folks climb this route solo; some with only approach shoes; others tote a full double rack. If you are a solid 5.9 climber, a small rope, single rack and pair of climbing shoes add a lot of security on the Grand. We did bust out the rope one other time on the Ice Cream Cone, but we were comfortable in approach shoes for the rest of the terrain that we covered.

Footwear

Your kicks are pretty important for this one. The Grand Traverse covers almost 14 miles and over 12,000 feet of vertical gain. You navigate a lot of varied terrain and footwear is important. I used one of my favorite light hikers with a custom Five Ten dot-rubber resole on the bottom. We carried climbing shoes so that we could move quickly and with greater security on the longest technical climbing portion, the North Face of the Grand Teton.

Layers

A good mix of layers able to combat the alpine chill, yet which are still breathable and comfortable with constant movement in a variety of temps, is critical. They aren’t needed, but I stashed a pair of boardshorts in my pack for moving through the midday sun.

Pack

You could certainly go smaller, but I like a light and compressible pack with real straps and full size hip-belt like the HMG Porter.

Traction

Twp types! We carried a micro-traxion to add a layer of security so we could simul-climb the grand Teton in as few pitches as possible.

We also carried CAMP aluminum ice axes and crampons. These were nice to have while navigating the Koven Col, and mandatory for our given bail route. We descended a snow slope somewhere underneath Cloudveil/Spaulding and it would have been impossible to navigate safely without an ice axe and crampons.

"Traction

Beta

The intel gathering for this mission felt monumental, and it was ultimately fundamental to our successful onsight of the Cathedral Traverse, the first half of the Grand Traverse. I uploaded a GPX track to the Gaia GPS App, then manually uploaded Mark Smiley’s beta found at MtnSense.com to each waypoint. Sure, you could argue that our onsight just got downgraded to a flash, but this combination of info made navigation a breeze….at least until we reached the Middle Teton.

Bivy Gear

We carried an emergency two-person bivy—warm-enough to use in an emergency, but not big enough to enjoy a few hours of real sleep in. I’d bring this same rig for another in-a-day push, but if you’re looking to do the traverse in two or three days, consider bringing a slightly more comfortable set up.

Food 

I can go a long way on Shot Bloks and GU Energy packets, but Sam Miller was the MVP in the food department. First he taught me about his special on-the go wrap recipe (below), then he shared a pouch of fresh smoked salmon on the South Teton. Total game-changer!

Alpine Arugula Wraps:

— 1 wheat tortilla

— Handful for extra spicy arugula

— Hummus

— Small handful craisins

— Feta Cheese

Rack and Rope

We went with a pretty standard gear assortment, carrying four alpine draws and a single rack of cams (using Ultralights where possible). The “larger” rack allowed for longer simul-climbing pitches and/or climbing security where we wanted it.

Our rope was small: a 60-meter 8.5mm Mammut Genesis rated as a half rope. The 60-meter length was more than sufficient for the rappels off Teewinot and Owen, and if we ever wanted more rope security on a challenging pitch, we could fold the rope over creating a real 30-meter half-rope system. Fortunately we never felt the need to do this, but it was nice to have the option.

Sleeper Crux

Don’t underestimate the easy stuff. Sam and I are both competent climbers with excellent endurance. We found that our lack of research on the last portion of the Traverse caused us more issues than we anticipated. Although we read that there were multiple 3rd-class options off various features on the back 9, we both felt like we were constantly climbing loose 4th and 5th class choss in the dark. This, coupled with our impending “greater-than-24-hour” Grand Traverse time, ultimately caused us to throw in the towel and head back to the Climber’s Ranch. We’re heading back in a few weeks to clean this up, but I will no doubt be glancing at the descents off Cloudveil and Nez Perce with a more focused lens.

As always, reach out with any questions and of course I hope this gear list aids you out on your own Grand Traverse adventure or elsewhere in the amazing Teton playground.

The Grand Traverse (er, The Cathedral Traverse…) Gear List
Gear Item Specifics  Details
Person Gear
Footwear
Approach Shoes Merrell MQM w/ custom Five Ten Dot-Rubber resole You are wearing these for most of the traverse. You need something sticky, but comfortable and durable.
Climbing Shoes La Sportiva TC Pros (sized up) We only wore rock shoes for a few pitches, but it’s nice to have the precision, especially your first time out there.
Active Socks Thin Darn Tough socks A thin and comfortable sock that you can wear for the entire traverse.
Upper Layers
T-Shirt Base Layer Merrell Merino I’ve been a huge fan of merino baselayers these days. Something to keep you cool in the summer heat, but that will dry fast and doesn’t stink.
Long-Sleeve Base Layer Patagonia Sunshade Hoody I used a sunshirt as my longsleeve for warmth and protection from the August sun.
Hardshell/Gore-Tex Jacket Merrell Fallon 4.0 Hardshell Rain Jacket A Gore-Tex rainshell to protect from potential summer storms and strong winds.
Down Parka Puffy Merrell Entrada Synthetic Puffy A thin to mid-weight puffy to keep warm when the sun goes down for an unplanned bivy.
Lower Layers
Underwear 2XU Run Compression Shorts A thin compression short for all-day wear. I find the thicker weave helps protect from alpine winds, but is cool enough for moving constantly throughout the day.
Softshell Pants Merrell Allpath Multi-Sport Pants A super-thin pair of softshell pants helps protect you from abrasion and the wind without getting too hot in the middle of the day.
Active Shorts for approach Patagonia Boardshorts It was pretty warm when we were on the traverse and moving quickly—it was nice to have a pair of shorts.
Head + Neck + Face
Helmet Black Diamond Vector Light helmet for all-day comfort.
Visor Merrell Visor I like a light hat or visor to soak up some sweat and block the sun.
Neck Gaiter Merrell Buff Head covering, sunglasses cleaner—all-around useful piece of gear.
Sunglasses/Eye Protection Zeal Caddis — Blue Mirrored Lense Dark enough to block the high alpine sun.
Hard Glasses Case Zeal Blue Soft Case I like a hard case to protect my sunnies for when I stuff them in my pack when the sun goes down.
Lip Balm + Sunscreen Dermatone Tin Lip and Face preotection.
Hands
Liner Gloves OR Windstopper Fleece Gloves It’s nice to have a pair of light gloves for the early morning approach and potentially colder alpine conditions.
Sleep System
Emergency Bivy SOL 2-Person Bivy Bag Not built for comfort, but we carried a 2-person emergency bivy bag.
1/2 Length Closed Cell Yellow ThermaRest Z-Light, 1/2 Pad (pack insert) This doubles as a pack insert, but 4-sections of the Z-ThemaRest are also good enough to sleep on.
Packs + Portage
Pack Hyperlite Mountain Gear (HMG) 2400 Porter A nearly perfect size for all of your gear and then some. This pack also climbs quite well and packs down nice and tight to your back.

Personal Climbing Gear
Crampons CAMP XLC 490 (Strap-on) These were great to have at the Koven Col and of course for bailing/descending from the North slopes underneath Cloudveil Mountain.
Ice Axe CAMP Corsa Ice Axe (50cm) This thing is so light, it was definitly worth bringing—especially when bailing.
Harness Black Diamond Technician Simple harness. You could certainly go lighter here, but I happened to have this one with me.
Belay Device Petzl Reverso 4 I like the Reverso because the sizing feel tighter on skinner ropes.
Small Locking Carabiners (3) CAMP Photon Lockers My current favorite small locking carabiner.
HMS Locking Carabiners (1) CAMP Core + (1) CAMP Nimbus I like the larger HMS Core for my belay device and use the Nimbus to clove hitch myself into anchors.

I just use a small locker to keep the kit together and hang it off the back of my harness.
Climbing Gloves Ocun Crack Gloves Really nice to have these for a few pitches and save myself the tapped up hands for the entire traverse.
Food + Hydration
Capacity for 3 Liters H20 2L Bladder + 1L Nalgene We filled bottles at the Koven Col, but carried what we needed to get us to the spring on the Lower Saddle.
Water Filter Katadyn BeFree w/ 1L Soft Flask My favorite on-the-go filtration system.
Food Enough for 30 hours Lots of great food options. We carried enough calories to sustain us through a 30-hour push.
