Slope Angle Shading released!

We’re now in our fourth year of offering backcountry ski guidebooks in rakkup, and we are really excited about our latest feature! Slope angle shading is now available for all our US backcountry skiing guidebooks on both iOS and Android devices. Simply be sure you have our latest app release, go to the Bookshelf tab, and tap the cloud icon to update your guidebook.

Avalanche safety educators have been telling us that Slope Angle Shading is one of the best tools for visualizing areas of high avalanche hazard and selecting safer routes in avalanche terrain. This transparent overlay immediately highlights areas with slope angles yielding the highest avalanche risk along and above your route, as well as terrain convexities, terrain traps, terrain that might be too steep to ski (such as cliffs), and even very flat areas where splitboarders like us might need poles or plan on walking.

According to the American Avalanche Institute, most avalanches occur on slopes between 30° and 45°, with peak risk at 37-38°. (Watch AAI’s short video about recognizing avalanche terrain.  We’re proud to partner with the AAI this season and offer rakkup guidebooks to their instructors and students.) We’ve used color gradients to show slope angle information with a high degree of precision. We applied a lot of computing power and our best programming tricks to bring you beautiful maps that are easy to download, display quickly, and keep working long after you’ve left cellular service behind.

In the past, many snow professionals used the premium versions of generic mapping apps to view slope angle shading. We think it’s even better to have this feature integrated into your guidebooks – not to mention that these apps have yearly subscription fees several times higher than our guidebook prices! Integrating all our route data with topo maps and slope angle shading helps you choose which zone and which line to ski based on today’s conditions without flipping back and forth between different sources of information.

Of course, no app can take the place of quality avalanche safety training, observation of your surroundings including terrain and snow pack, and proper decision making. But the most effective part of avalanche safety is staying out of avalanches, not digging out of them, and better information can lead to better decision-making. If rakkup can help you select a quality descent, stay alive and safe without getting lost, and have more fun away from the crowds, then we’ve accomplished what we set out to do! 

We hope you’ll check out a rakkup skiing guidebook and tell us what you think. Many of our digital guidebooks are also available with a companion printed ski atlas or folding map from our friends at Beacon Guidebooks as a backup and additional reference.

Many thanks to our friend Jamie at Teton Splitboarder for encouragement and technical advice that helped us execute and improve our work.

Finally, a reminder to make sure you know how to turn off the cellular, bluetooth, and Wi-Fi radios on your phone in the backcountry and keep it at least 30 cm away from your avalanche beacon. GPS reception is a passive operation that won’t interfere with your beacon’s signal so you can still pinpoint your location with the radios off.

Happy skiing and splitboarding to everyone!

Backcountry Skiing and Snowboarding — a new adventure for rakkup

Over here at rakkup “World Headquarters”, our homes in Seattle, we are climbers and we love climbing. But like many climbers, we live near the mountains and love playing in them in a variety of ways, and we have winters to get through. And in the Pacific Northwest, we have plenty of precipitation which turns into an amazing amount of snow at elevation.

Early Days – transitioning on a Voilé split, 2005

So, it’s only natural that Rob and Todd love to get out on the snow. While we both have skiing in our history, we’ve become pretty hooked on snowboarding. We can even claim to be pretty early splitboarders; here you can see a picture of Rob starting a transition in the Herman Saddle zone near Mount Baker in the winter of 2004-2005. What we can’t claim to be is snow experts. In December of 2005, we managed to demonstrate our lack of expertise by spending an unplanned overnight near Stevens Pass. (That epic led to our first purchase of a GPS, which eventually became the very unit we used to make the first rakkup rock climbing guidebook!)
We have had friends tell us for years that our app would be a great fit for backcountry snow. In the last year, two pieces came together to make that idea irresistible to us. The first is that our awesome partner, Wolverine Publishing, told us about the success and the quality of their guidebook Backcountry Skiing California’s Eastern Sierra. The book’s author, Nate Greenberg, was interested in the potential of his content combined with an app, too.
Meanwhile, Rob had taken a couple of snowboarding trips to different zones in Alaska, with Jamie Weeks as his guide. As Rob and Jamie became friends, Jamie wondered aloud about what a great guidebook app would look like for the ski terrain near his home in Jackson Hole, and expressed some enthusiasm for the project.

Nate is the director of the Eastern Sierra Avalanche Center, and Jamie is an AMGA certified snow guide and avalanche educator, well known for his work as Teton Splitboarder. What Rob and Todd lacked in experience and technical expertise, they now had in their partners. All four shared a passion for the project.
Together we bring you the newest update to rakkup, and our first two guidebooks for backcountry skiers and snowboarders: Teton Pass Descents and Backcountry Skiing California’s Eastern Sierra, a digital enhancement to the existing print title from Wolverine Publishing.
Lots of work went into developing guidebooks that are clear and easy to read, with symbology and maps that let you browse and choose quickly. We added topo maps with contour lines, a necessity in ski terrain. We are especially proud of our filtering feature that lets you apply criteria from your local avalanche center to eliminate runs in higher-risk terrain based on slope angle, aspect, and elevation and choose from the runs that remain.


Best of all: Search for terrain, or Filter based on critical information factors (like those presented in an avalanche advisory).

We’ve already been told that this app is the most compelling and exciting backcountry ski app yet. Yet we know that this is just a beginning. For one, we have many more guidebooks already in the works, from respected and talented authors all over. (We are always looking for more! Let us know if you want to write a guidebook.) Secondly, we have plans we think you will love, from sharing your adventures with friends, to visualizing the latest reports and information to keep safe. We’ll be adding features to make this app a tool you won’t want to head into the backcountry without!
So, get out there and shred your own patch of pow! Give one of our guidebooks a spin and tell us what you think.

The making of our Joshua Tree guidebook

Joshua Tree in amazing light

This week we are launching the rakkup digital version of Joshua Tree Rock Climbs by Robert Miramontes, from our partners Wolverine Publishing. This release is an emotional one for us on several levels and we thought it might be interesting to share the story of how it came to be. With a sense of great pride and accomplishment, gratitude for partners who helped us and believed in us, and sadness at a recent loss, we bring you this book and hope it is your companion for some great climbing days this Winter.

The good folks at Wolverine have been our most important partners for the last couple of years, and it all started with a visit to the Western Slope. We admired Wolverine as an early leader in smartphone versions of digital guidebooks, and we had recently seen the news that they were discontinuing the first generation of apps they had released because they proved to be difficult to update. Excitedly, we drove from Boulder to the Rifle area to pitch our platform. There we not only received the warm hospitality of Dave Pegg and his wife Fiona, but also the gift of their faith in us. After our meeting and a super home-cooked meal, they decided to entrust us to release digital versions of their books at a time when our catalog consisted of about two titles.

Some of you may have heard of the tragic loss of Dave Pegg last weekend. He was a great business partner but more than that. We counted him as a friend and admired his energy, business smarts, integrity, and pure love for the people and places of climbing. Several other authors told us his books set the standard in North America for detail, readability, and appearance, and we agree. Our last email from Dave was the “green light” to release the Joshua Tree guidebook we built together, and after we conferred with Robert Miramontes (its meticulous author), we agreed that Dave would want to see this go forward. Therefore we see this as something of a tribute to the beautiful books he made and the community of people he brought together to do it.

When you pick up the book, you are immediately struck by its beauty. The layout is clean and readable, the depth of the descriptions is amazing, the photos are simply among the most stunning of any guidebook (but also perfectly framed to help find your route), and the heft and thoroughness is mind-blowing. Turning this into a digital guidebook was a daunting task, but from the very first day that we prototyped rakkup’s turn-by-turn navigation we talked about Joshua Tree as “nirvana”, the ultimate place where it was really needed. We had already checked that GPS signal was accurate way out in the park beyond cell phone service.

It turns out, it took a team of four people and nearly six months from the time we started to pull it all together, and this book pushed our platform and our technologies to new heights. Todd was responsible for processing the original book files and using our automated import tool to parse all the sector, wall, boulder, and route descriptions and data. We structure the text and put it in a database so that climbers can quickly, sort, filter, and find routes.  Our friend Tom Moulin helped with the enormous task of processing all the photos, preparing and labeling them to look great on mobile displays. (Tom is also a professional photographer, and author of the superb Southern Nevada Bouldering guidebook in his own right.) Robert, the author, used our web-based map building tool to draw a map of all the roads and trails that connect the 3,057 climbs and boulder problems with 201 miles of roads and trails. It boggles our minds to think of the time and knowledge required to put this together, and we feel sure every rakkup user is going to appreciate Robert’s setting this all down in a way we can benefit from when we climb. Watching Robert work forced us to make our tools better. I regret that some of the improvements will come too late to help this Herculean task, but I know all future map builders will benefit.

For my part, I found this guidebook was on such a daunting scale that I had to rewrite both the iPhone and Android versions of rakkup to give a better experience with it. First, we added smart downloads that let you open the guidebook and use it within about 15 seconds of your purchase, and seamlessly download nearly 600 photos in the background and as you need them. Once they are cached the entire guidebook works offline so you can use it anywhere in the park. Next up, I did a rewrite of the map drawing code to handle the complexity of the map, which includes over 5,300 sections of road and trail, 3 or 4 times as much as our next most complicated map. Both iOS and Android offer a way to break the drawing up into small units of work so you can zoom, pan, and tap and feel a responsive app even as we show you where all the climbs are. This requires us to do all the math of converting GPS coordinates into pixels, so it was a fun challenge.

Finally, I had to address the speed of route calculation. In our other guidebooks it felt nearly instantaneous to calculate the route from where you are to the route you seek, but it took a few seconds at J Tree on the iPhone app, and the Android app was just overwhelmed. Our algorithm was already pretty good, but I added a caching strategy to pre-calculate some things, and now we are back to instant response and reliable routing on both platforms. Along the way we used some new quality-control tools to validate the map and fix a few errors that crept into the map data, too.

This book was really what we had in mind three years ago when we labored to create rakkup. I love ability to filter a huge database of routes and see just the ones you want in a list or laid out on the map (by morning shade or afternoon sun, 3 or 4 stars, trad or sport or bouldering, just the right range of grades, and more). I can’t even imagine visiting Josh again without relying on rakkup navigation, as one who has been lost plenty and seen the labyrinth of stone in the park. And Robert’s beta, opinions, and ratings clearly seem to reflect more climbing experience there than I and my friends could ever hope to amass.

We loved being part of a team that came together to make a piece of work cooler than any of us could have done on our own. We got Wolverine’s permission to bring it to you at an amazing price. And we think that since we all rallied together around an effort started by Dave Pegg, it is a fitting tribute to how much he gave to the climbing community. You’ll be missed, Dave, and we will work hard to keep the level of quality you would have wanted, and to get out and climb as often as we can, as you certainly did.

Remembering Dave Pegg

Todd and I woke up to the sad news of the passing of Dave Pegg this morning. We still don’t know much but we’re saddened and took time to share memories with each other today.

Dave was the energy and the soul of Wolverine Publishing, and probably did more to raise the standard for North American climbing guidebooks than anyone in memory. The work he did helped thousands of climbers have happier climbing days and influenced many other authors who told us straight up that Wolverine’s work set the bar for them.

Todd and I met Dave and Fiona less than two years ago at their home near Rifle, when rakkup was in its infancy. They were among the very first to believe in us and put their trust in us, and Dave was a great partner to work with. He was honest and conducted his work with integrity, and he did what he said he would do. This is a rarer quality than some might think, and we valued it. He had vision for the future but tempered with the practicality he needed to make the present work.

But beyond that, we had a great admiration for Dave because he made time to do the things he loved, most especially climbing, and always seemed to be in the places and around the people he loved most, with a smile on his face. He worked hard and played just as hard.

Wolverine was pretty much the first to have apps for their guidebooks, way ahead of their time. We jumped at the chance to meet and earn the opportunity to build on the incredible library Wolverine had accumulated. Todd and I drove across the state of Colorado for a meeting and in the process got to enjoy hospitality and make new friends. On a later visit, we got to visit Dave’s new somewhat secret new crag and watch him work on his project of the day. He was clearly in his element and it was a beautiful thing to watch.

We will miss him and share condolences with all who feel this loss. If there’s anything we can to do preserve and build on the legacy that Dave created, we will give it our all as he would have.

Exit 38 Rock Climbing this summer? Try our new guidebook!

Exit 38 Rock ClimbsTodd and I have been climbing at Exit 38 now and again since the late 1990’s, and we know it’s a great resource for Seattle and Western Washington climbers. The drive out to North Bend is easy, and the crags stay cool and shady even on hot summer days. If you have ever been climbing at Exit 38, you know that it’s got a great array of moderate climbs from 5.6 to 5.12 and some excellent first leads for the beginning outdoor climber. The short approaches and friendly bolting and equipping of the routes are added bonuses.

Our friends at (with whom we partnered to create the Exit 32 Rock Climbing title for rakkup last year) have a guidebook to the area, but its hard to find a copy this year and the new edition likely won’t be in stores in time for the summer climbing season. We thought this would be a great opportunity to showcase the advantages of digital distribution, so we set out to create a rakkup guidebook. You can buy the resulting Exit 38 Rock Climbs title now in our app or here on our website. Like all rakkup titles, it includes great mapping and our much-loved turn-by-turn directions to navigate you to every climb using the GPS in your smartphone.

We’ve included all the climbs at the most popular and highest-quality areas: the Substation, Write-off Rock, Nevermind Wall, Deception Wall, We-Did Rock, Hull Creek Wall, and Amazonia. We’ve even documented some climbs that have never appeared in any guidebook before. As always with rakkup, it’s fast and easy to search, filter, browse by grade, and map all the routes.

This was a fun project for us, as we took the opportunity to try some new technologies and teach ourselves some new tricks. We used some cool new Adobe software for iPads to sketch routes and annotate photos while standing right at the crag, and some cool “stitching” techniques to create panoramic views of some walls that would be impossible to take as a single image. As a result this guidebook features detailed color photos of the routes with clear lines making it easy to identify different routes. We think it’s the best guidebook yet for hassle-free climbing at Exit 38.

We’ve kept the price affordable and continue to offer an even less-expensive option to “rent” the guidebook for 2 months at half the usual price, if you aren’t a frequent visitor and just want to give it a spin. Happy climbing!
