A Great discussion on the Digging of Snowpits

From showing weak layers of snow, to the depth of the seasonal snowpack. Snowpits can be a vital source of information when traveling into the backcountry.  But are they always nessasary? This link will take you to a great discussion and breakdown of when and why digging a pit is vital.

How to Break Down Weather Patterns before heading out to go Touring

During a typical season, I usually travel a little bit, but for the most part, I tour here in my home range-- The Cascades. The Cascades offer a more stable snowpack than other areas, as well as a longer lasting seasonal snowpack. Plus, when the seasonal snowpack melts, there's always glaicer riding. I often sit at my house in Seattle or in Greenwater, Washington (that's right near Crystal Mountain) and think about where might be a good place to get out and go touring, and the first place I always look is to the weather forecasts. Whether it's spring touring with perfect corn or powder hunting midwinter, there is a lot of planning that goes into a good backcountry trip. While I maintain a list of places I'd like to go and lines that are asking for a slayin', I ALWAYS plan my trip around the weather. I can't emphasize this enough. If you were to ignore this very important step, and venture unawares into an area where the avi conditions are terrible or it looks like it's gonna rain, you're almost guaranteed to have a trip that's somewhere between dangerous and unenjoyable, so appropriate planning is absolutely crucial. For weather-based trip area planning, this is a breakdown of my process for here in the Cascades. Step 1: Check out a generalized, or large-scale weather forecast for freezing levels and large-scale precipitation patterns. In the Seattle area, we're close to a lot of different areas where backcountry snowboarding is available. Usually the forecast for the Olympic peninsula, for example, is very different from that of the North Cascades. I like the Washington State Department of Transportation site because they are pretty good about listing both the snow levels and chance of sun. Each state has their own informational site, which may or may not be as good as this one. For WSDOT, I like the Mountain Passes forecast. It's a good place to check for freezing levels. If you are willing to travel, freezing level information is invaluable. At this point, you're probably asking yourself what the freezing level and precip likelihood is going to do for you. Which brings me to the next point: Why Check the General Forecast?
  • Sun vs. Rain: You don't want to be ill-equipped for a tour. Whether it's sunshine or a rain storm, this will give you an idea of how to plan your equipment and plan for the day. If its' going to be a wet day you may want to bring extra layers and gloves in case your gear gets soaked.  If it's going to be sunshine, you may want to bring sunglasses and sunscreen. While this gives you a good idea about what to expect, never depend on it being 100% correct and always prepare for the worst possible situation.
  • Freezing Levels: No one likes to hike a few miles in the rain only to be soaked by the time they hit snow. Here in the Cascades, it is safe to say the freezing level fluctuates between sea level and 7000 feet during fall spring and winter months. Take your objective's altitude into consideration when deciding where to tour. At Snoqualmie Pass, the peaks summit around 5,500 feet. At Crystal Mountain, they summit at 7000 feet.  On a hypothetical day with a 5,000' freezing level,  personally, I would like to go to Crystal and not have to deal with the rain. Hence, freezing levels are key.
Okay, now you know where it's snowing, raining, sunny, and breezy. This brings us to... Step 2: Zero in on more specific weather and avalanche forecasts for your chosen destination. Now that you have a general idea of the forecast, it is time to break it down to a specific area. While general forecasts are great, they don't tend to be overly scientific. A great resource for accurate point-forecasting is NOAA (The National Oceanic and Atmospheric Administration) which allows you to get pin-point forecasts. For example, here is the link to a forecast on the south side of Mt. Rainier. What does the pinpoint forecast tell you that the general one won't? Say, for example, that you've decided to tour somewhere on the West side of the central cascades near Mt. Rainier National Park. Reading the specific forecast could be really helpful in this circumstance. There is a lot that goes into pinpoint forecasts.  Whether it's wind direction or rain shadows, pin-point forecasts take all of these factors into consideration. Sometimes the general forecast says that there will be a few inches of snowfall in the Central Cascades, but a pinpoint forecast calls for 9 inches on the south side of Rainier. This makes total sense, because Rainier rises over 7000 feet above all its surrounding peaks causing the clouds to release more moisture before completely passing over the region. This is the type of information that the WSDOT website won't convey. If you want 9 new inches of powder, clicking on that NOAA forecast would probably have done you some good in this example. Another scenario I come across often and get asked about frequently is the following one: Say its going to be partly cloudy and I want a chance of sunshine. I have a saying for the Cascades that goes, "When in doubt head east."   What this means is by the time clouds reach the eastern side of the Cascade Crest, there is little to no moisture left and the weather conditions will not be nearly as harsh as the west side. If you don't have the option to get on the east side though, take into consideration the topography of an area where you plan on climbing. If the winds are heading from the west, try heading to an area which is sheltered from the western winds. A lot of times you will find that clouds prefer to go around peaks, so you may want to climb an east facing slope.  Beware of wind loading, which I break down lower in the page.  You will find that rain shadows make a huge difference in the severity of a weather pattern. 3. Next is the biggest most important link in this entire blog. The Avalanche Forecast which is broken down to a color scale of 5 separate categories (Low, Moderate, Considerable, High and Extreme. This forecast is a standard used all around the world so whether you are in New Zealand or Seattle you can expect the same format for avalanche forecasts. Here is a link How do they get the Forecast?
  • The people who put out the forecast are trained professionals whose years of experience are available with just a simple click. Thanks to the info they get from digging snow profiles they can give you daily updates on what the snow is doing, whether its stable or sliding, safe or unsafe.
Can I still tour if it's a high avalanche danger?
  • There are still pleanty of options but I wouldn't recommend climbing up an exposed couloir.  That will have to wait for another day. Mellow slopes below 30 degrees rarely ever slide (not to say they don't) but it would be much safer to stay in semi dense forests.
4. Next I refer to the telemetry of a certain area, whether its Camp Muir on Mt Rainier or the summit of Crystal Mountain. A telemetry station is a piece of equipment left in a certain area to give readings about specific weather related information. You can get info like wind directions, temperature readings, and precipation amounts without leaving your computer. These are usually updated within a hour  or so and go back 5 to 10 days. Here is a link to multiple telemetry stations and a quick breakdown.

  • The hour is based off military time which is a 24 hour clock. For example 1400 is 2 P.M. and so forth.
  • Temp is the temperature at that certain elevation. For example the forecast above states the elevation at 5500 feet and it was 53 degrees at 2:00 p.m.
  • Wind Average and max break down the MPH of the winds for example at 2:00 p.m. the average wind is 4 m.p.h. and gusts up to 9
  • The precipitation totals are key to understanding a area. The total Precip at 2:00 is .59 or 3/5 a inch of rain.
But what does the precipitation totals mean for snow?
  • A very general breakdown is that every inch of rain is equal to a foot of snow.  If cold enough, you would expect around 7 inches of fresh snow according to the above example.

5. The final thing that I do before deciding a tour location, is study the areas' recent snowfall and temperatures using all four of the links I provided above.
Take into account Precipitation Totals
  • This is an important thing to do, but takes a lot of time to master. Say you could only make it out on the weekend but you are wondering how much snow had fallen throughout the week? With the telemetry forecast I mentioned above, you could easily gather the information. Say two inches fell on Tuesday and 5 inches fell on friday and the freezing level is below freezing point.  It is safe to say there is going to be 7 inches of new snow.
Now take into account temperature
  • This is a delicate balance in the Cascades where one day an area is 20 degrees then the next day its going to be 40 degrees. What can I expect? The snow is going to get heavy as the sun comes out and the temperature rises.  When in a situation like this, I try to head to north facing slopes where being covered in shade causes them to be 10 degrees colder, holding better quality snow.
  • Lets say after the 40 degree day the temperature goes back to 20 degrees.  What can I expect? All of the slopes that had baked in the sun the day before have probably developed an ice layer.  When the sun hit the fresh snow it started melting but with freezing levels dropping once again, it refreezes on the surface. It can be anywhere from one cm to a few inches thick, causing what was decent skiing the day before to be unenjoyable.
With a general understanding of forecasts, you have the opportunity to get an idea of what is in store for you in the mountains without leaving the comfort of your home. Like I mentioned before, at first it seems confusing but after some time you will, as we like to call it "Know before you go!"

Important Gear to get into Splitboarding

Important Gear to get into Splitboarding

This is a basic guide of the things you will need to start splitboarding. Without having a single piece of gear mentioned on this page I highly recommend not entering the backcountry. Board There are a lot of options out there so you should first consider what type of conditions you plan on riding. For example I tour in everything from 3 feet of fresh snow to 45 degree icy steeps, so I in turn would want a versatile board. There is everything from powder specific boards to big mountain boards, so make sure to check out the size, weight and construction before making this choice. Price Range: 599.00 - 1299.00 Here are a few Gear Reviews of boards I have personally tested out. Bindings Back in the day splitboarders only option was Voile slider plates, these plates were placed under your normal bindings at a sacrifice of a half inch riser under your feet. No longer are you stuck with the Voile slider plates. Your options are Dynafits, Spark R& D, Karakoram and Voiles light rail system. All of which are splitboard specific bindings and integrate a slider piece into the base of the binding . I advise using one of these systems compared to the slider plate if you are looking for a solid board feel while riding down. Price Range: 199.00 - 599.00 Here are a few gear reviews of Systems I have personally checked out. Skins Imagine having a car without wheels, that's what it is like to have a splitboard without skins. This important piece of the backcountry puzzle is available from multiple different companies and vary in different shapes and sizes. While Voile makes personalized skins for splitboards that doesn't mean you can't use skin from other companies like Black Diamond or G3. Here is a conversation on this topic. Price Range: 149.00-169.00 Here is a gear review of some skins. Poles As a snowboarder I prefer not to ride down a slope with ski poles in hand. For that reason I go with collapsible poles which come in both Dual lock and tri-lock systems. There are numerous companies who offer them but I prefer the Black Diamond expeditions. They are light weight, easy to use, and the flicker locks work in the worst of conditions, not to mention you can alter the poles to include whippets, which are mini ice axes. Price Range: 89.00-149.00 Beacon Out of all the equipment you have in your arsenal, none are more important then the Beacon. This is quite literally your lifeline in the backcountry and as I like to think, the one piece of gear that is going to save your touring partners life. Until a few years ago beacons used analog mode but as of recently they have switched over to digital. When purchasing a beacon remember this, The more antennas used the more precise it will be when finding burial victims. Price Range: 299.00- 499.00 Still working on a review of Beacons. Probe You want to look for the perfect balance in a probe. Something that is light weight and compact yet built strong enough to break through firm surfaces. After a avalanche rips down a slope it quickly settles, becoming firm blocks of snow. With that in mind always go for a strong durable material. The longer the probe is the better, why you ask? a 90 cm probe is useless when you are buried 95 cm under the snowpack. Price Range:49.00-99.00 Still working on a review of Probes. Shovel There is a lot that goes into a shovel. Its construction, material, handle layout and weight. A shovel can be a lifesaver in more then one way. Yes it can dig a friend out of a avalanche but it could also provide shelter in dire conditions and emergency situations. There are quite a few companies on the market that carry shovels so make sure to check out your options before biting the bullet and purchasing one. Price Range: 49.00-99.00 Still working on a review of Shovels. Backpack Unless you want to carry all this vital gear in your hands you better get a backpack. When choosing a touring backack look for a good layout in design with multiple pockets and easy access to your shovel and probe that has durable fabric. Also look to see if the pack has separate pocket for wet gear, ice axe loops and ski straps. Price Range: 99.00-699.00 Here is a Gear Review of different backpacks available.
