Gear Review: Petzl Leopard LLF Crampons

I picked up a pair of Petzl Leopard Crampons towards the end of last winter for a back-country ski trip to Iceland. While I had been happy with my Petzl Vasak’s I wanted to shed some weight from my back-country touring kit and the Leopards do just that! I pair them with the Arcteryx Procline Boots which happen to be 45% off right now (just sayin’) Let’s take a closer look at these crampons to see if they are right for you! First the manufacturer’s deets!

Alright, that’s out of the way so let’s breakdown the good & bad starting with…

Weight/Pack-ability

This was the biggest reason I chose these for my ski mountaineering kit. When your crampons only weigh 11 ounces it is hard to justify not packing them “just in case”. The CORD-TEC adjustment system lets them pack up into the smallest stuff sack I’ve ever used for crampons measuring about 7 by 4 inches.

Sizing/Fit

First make sure you select the right model! For ski boots you want the “LeverLock Universal” (LLF). The regular “FlexLock” (FL) model is suitable for hiking boots with or with out front and toe welts.

I’ll admit I was skeptical about sizing a crampon that joins the heel piece to the front piece with string! Ok, maybe “string” is not the right word. The “CORD-TEC” is actually a woven 100% Dyneema cord. I measure it just shy of 5 mm (3/16 inches). That would give it a breaking strength around 6000 pounds… so not “string”. Dyneema is also highly resistant to abrasion.

Petzl Leopard Crampon Review — Joined with bar-tacking, this cord is replaceable but unlikely to need replacing

Petzl does sell a replacement for it if you ever wear it out somehow. I have a hard time imagining how much use it would take to requirement, but the option is there.

Adjust-ability

I found the CORD-TEC system to be very easy to adjust for both of my ski boots. No tools required an quite intuitive. Do not be intimidated by the instructions, once in hand you could pretty much size them without looking at the instructions, but if you are having any issues give them a look!

DEAL ALERT!

Ok, sorry about that, back to the crampons!

Performance

These have been tested over a few thousand feet of snow climbing in on neve, spring corn, and classic NH “windboard”. For an ultra-light aluminum crampon they perform great! They have not, and will not, be tested on waterfall ice or mixed rock routes. They are not designed for that and I’m sure such uses will shorten their life-span. So far they have only been in contact with snow but I’m not too worried about walking over short sections of granite to get to the next patch of snow this Spring. It’s gear. It should get beat on from time to time! These will be my choice model for my next trip to climb in the Cascades.

Summary

These are for ski mountaineers, back-country skiers, and riders who have found themselves on a steep slope wishing they hadn’t left their crampons in the car. These could also be a nice step up for many winter hikers who sometimes rely on Kahtoola MICROspikes in terrain where more aggressive traction would be more appropriate. Just make sure you get the Flexlock model. Skiers should get the LevelLock model. Finally these are for anyone who is looking to shave ounces off their total kit while still having the tools they need to reach the places they want to play. If that’s you then you should consider checking these out!

Exploring a new slide path

March 29, 2018 Backcountry Skiing, Trip Reports backcountry skiing, mount washington, ski the whites, ski touring

The final days of October 2017 brought over 6 inches of rain from the remnants of Tropical Storm Philippe to Mount Washington which resulted in major flooding all over the Saco River Valley (which had risen to 14 feet above flood stage!). It also apparently ripped a nice new slide path near Burt Ravine on the west side of Mount Washington, only 10 minutes from the Cog Railway.

I came across this path a couple days ago while exiting Burt Ravine and noticed it looked quite fresh but didn’t really put it together that it was only 5 months old until I got home and did a little research. While I’m sure a local or two has likely quietly grabbed the first descent I needed to get back and put a run in on this new path pronto, and this morning I made it happen.

Here’s the skinny…

I skinned up the Cog reaching Waumbek Tank in about 30 minutes. At 3,920 feet I picked up our skin track from a couple days prior and contoured/bushwacked back to the slide path (ten minute bushwhack). This skin track enters the slide at mid-path, so I set in some kick-turns and climbed up to about 4,200 feet, the high point on the path.

From here the run drops 500 feet to the south most tributary of Clay Brook, the main brook fed from Burt Ravine. The average slope angle was 30 degrees with a max pitch of 34 degrees and is an almost true NW aspect.

I skinned back up to the established bushwhack and exited back to the Cog, reaching the car in amount 2 hours and 20 minutes from departure.

Given I waited about 20 or more minutes for some friends to arrive before dropping I would say this would be pretty easy to hit car-to-car in 2 hours. It’s a really nice little run that is super accessible (though it costs $10 to park at Marshfield Station). New slides like this are so exciting. While extreme weather can have devastating effects on life & property the power of Mother Nature can also open up new ski terrain from time to time, and this little shot in the woods is well worth the effort.

Next time I head there I will try the bushwhack from the Switch House along the 4,200 contour so I can come in from the top, though the lower traverse would still be the easiest way out. I also want to go ahead and ski out Clay Brook to the Jewell Trail but I’ll be doing that on a day where I don’t have an early turn around time set.

Trip Report- Burt Ravine (3/28/18)

March 28, 2018 Backcountry Skiing, Trip Reports backcountry skiing, burt ravine, mount washington, ski touring

Yesterday I got to ski a new-to-me ravine on Mount Washington, Burt Ravine, the one just to the left of the Cog Railway when viewed from the west. We skinned up the Cog and reached the top of Airplane Gully in 2 hours and 10 minutes.

Jordan, who had climbed up from the east side of Washington via Pinnacle Gully and was meeting us on the ridge, dropped into nearby Turkey Shoot while Benny and Nick sent Airplane Gully. Conditions were stiff but edge-able wind-board. Brit and I made our way over to the top of Burt Ravine and dropped in.

I would find out later through Facebook that this was likely Marty of Alpine Endeavors, who sent me a pic of us from his vantage…

Burt skied pretty well with a variety of snow conditions as you can see in the video below. Once we got to 3,800 feet I found a skin track leaving the drainage that appeared to be heading back to the Cog. Consulting the topo made it look like it might contour back to the Cog around Waumbek Tank, and be quite a fair bit easier than the 1.2 mile low-angle thrash to pick up the Jewell Trail and exit. We decided to commit to it. It climbed about 150 feet with a few switch backs then crossed a really enticing new slide path.

The upended trees and dirt made this new path look quite fresh and the rumor is it formed during the Fall 2017 weather system that brought massive flooding to the Mount Washington Valley.

The skin track seemed to stop on the other side of the path so I continued following our contour and intersected with the Cog about 300 feet above Waumbek Tank. It only took us about 30 minutes of bushwhacking to get back out of Burt and from what I hear that is much better than trying to negotiate the lower drainage.

We exited down a still pretty firm Cog run and called it a day. Mileage was just over 5 miles in 4.5 hours with 3,264 elevation gain/loss. It looks like the Higher Summits Forecast isn’t to appealing for the next few days. Let’s hope the weekend brings some decent Spring skiing weather for the last avalanche course of the season!
