Plan B's

I spent the morning packing, repacking, weighing, and sorting through our supply of food.  After a few hours of work (and tasting- to make sure it was all fit to eat of course, especially the chocolate) we now have five cardboard boxes of similar weight organized into: 1 that will serve as a pantry holding enough of each item to last for a few days and the other 4 boxes holding the rest of the food.  The idea is that when we pull into camp, we won't have to rummage through 250 pounds of food to find a bag of raisins or a pinch of salt.

Ice Picks- kinda like retractable claws for humans
Throw rope
Two new pieces of gear showed up today also: a throw bag/rope and a set of ice picks.  The throw rope is the same style used by whitewater boaters and, even though the water is frozen, will serve the same purpose: to get a safety line to a person who unexpectedly ends up in the water.  The ice picks are also used in case of a break through the ice, but instead relying on help from other people as with the throw rope, ice picks allow a victim to pull oneself out of the water and back up onto the ice.  These safety items are a reminder that anytime you venture out onto a frozen lake, there is an ever present risk of breaking through.

Traveling on the frozen lakes means flat and relatively easy travel compared with pulling a toboggan through the woods.  Where the bush is full of downed trees, deep pockets of snow, and hills, lakes and frozen marshes/bogs give you a nice flat surface that, if you are lucky, has been scoured by the wind either down to the ice or down to wind packed snow.  Of course, spending 3/4 of our time on frozen water brings risk, but knowing a few basic principles of ice and how lakes freeze can mitigate much of that risk.  Any place where there is current like at inlets and outlets of lakes or on rivers, where spring water flows into a lake, or in and around pressure cracks all should give you reason to pause and check the ice's thickness.  Bottom line is if you are unsure as to the safety of the ice- check it out by chipping a hole and measuring the thickness- 2"at least are needed to safely hold a person.

Along that thought, we are each planning on taking some ice fishing gear.  The fishing gear is not only a pleasant distraction from the daily routine of life on trail and a (possible) source of fresh food, but it also represents another level of safety in case there is an accident involving thin ice (i.e. losing a toboggan to Davy Jones' locker) or if the weather (extreme cold or heat, wind, heavy snow and/or wind) delays us and keeps us on trail over the 25 days we have packed food for.  Thanks to the nice folks at Anglers All in Ashland Wisconsin for helping us pick out a small and efficient ice fishing kit for this trip.

The Bigger Picture

One of the great challenges we are passing on to our children is figuring out how our relationship with the natural world, i.e. Nature, Outside, the Wild, fits into our current societal scheme. While we are all on our own path towards reestablishing that connection individually, as a whole we have many incongruities between the way we think of the natural world and the way we treat it. One place where those incongruities are most visible is when industry (usually resource extraction) takes place in, on or adjacent to preserved public lands. This is not to make a judgment as to the value of those resources, we are after all taking a solar power kit on this trip and the demand for copper in the alternative energy industry (like solar panels and batteries) is one key reason for the intended development of the Pebble Mine in Alaska which threatens the health of one of the world's greatest fisheries in Bristol Bay and its tributaries. So while the issue of development /progress vs. preservation of wilderness may not have a clean answer, we are not tackling head on the glitches between us and rest of the life on Earth.

Those glitches in ethos become evident anywhere our modern civilization comes in contact/conflict with places and people who present a barrier to our system's need for natural resources, undeveloped land or locations of social/economic/political importance. We are taking actions that prove our understanding of the importance of a sound global ecosystem- through the preservation of undeveloped land, reestablishing the populations of endangered species and legitimizing the idea that not only do we need an intact global ecosystem for our physical and psychological health but that we also have the ability to alter the function of the global ecosystem in ways that threaten our current understanding of life on Earth. But for all of our actions to save, there are just as many that will threaten any gain we have made in the past. The Boundary Waters Wilderness, just like the Arctic Wildlife Refuge, is now subject to that tension where wilderness and progress conflict.

There are plans to develop a copper-nickle mine just outside of the Boundary Water's southern boundary using a method of mining called “sulfide mining.” Essentially this process involves digging up a bunch of Earth, in this case sulfide-rich Earth, separating out the copper and nickel, and disposing of the waste ore. The problem is that when that sulfide rich ore is exposed to the environment, sulfuric acid can be created and that is bad on the good-bad scale. This process can lead to water pollution, ecosystem disruption and a loss in biodiversity. Now, whatever side of the fence you come down on, pro mining or anti mining, it is important to be knowledgeable about issues that impact our public lands.

The Boundary Waters Canoe Area Wilderness was created in 1964 and includes over 1,000,000 acres (1,500 square miles) of rivers, lakes, taiga/mixed conifer- hardwood forests, moose, wolf, trout and exposed bedrock as old as any on Earth. All of this and no permanent signs of humans- no roads, buildings, or infrastructure like telephone poles or radio towers. There are campsites with fire grates, latrines and there is the usual detritus that seems to follow humans everywhere we go- pop cans, plastic bags, flip flops (just the left one's though- if you ever see a lone flip flop I almost guarantee it is a left, not sure why no one loses the right ones...) but none of these are permanent and the BW remains, as the Wilderness Act says “as an area where the earth and its community of life are untrammeled by man, where man himself is a visitor who does not remain.”

One Week and Counting


Today is a big day for this trip- after months of planning and training we are now just 7 days ( six and a half actually) from taking our first steps in the BW.  Food is starting to pile up, gear is in various forms of construction/ completion and my tent is starting to take on the appearance of a northwoods outpost.  One of my favorite reasons to take on a lengthy expedition-style trip like this one is the degree of planning, organizing, and figuring just how you are going to pull off such an adventure. 


New ice chisel made from a 1 1/2" wood slick,
a section of steel pipe and black ash handle.





For example, this trip has had us dehydrating meat, fruits and veggies, welding tools like the ice chisel in the picture, sewing bags to hold gear and also fit on the long and narrow toboggans, retrofitting/ modifying the gear we have that doesn't work quite right and inventing pieces of kit that you just can't buy anymore.  I spent the better part of a day last week figuring out a new snowshoe binding that gives me a solid feel but that is soft enough to work in conjunction with moosehide mukluks.  What I came up with is something that you can't buy (unfortunately because they work great) and that is tailored to fit my needs and the environment I live in.  


We will be heading up to Ely next Monday night and will be staying over 'till tuesday morning.  If all goes according to plan we will be loading up our toboggans and heading out from the end of the Gunflint trail on Wednesday morning and returning to Ely on or close to the 11th of March.

Pemmican

Preparing for 50 days of Pemmican
by Jarell Friesen
I have embarked on a personal journey to test my body’s ability to subsist entirely on the traditional first nation food, pemmican. The experiment will take place during a five week period starting Feb. 1st - March 18th 2014 during a 100+ mile snowshoe expedition through the Boundary waters of northern Minnesota.
A Brief History of Pemmican: Pemmican is a concentrated nutritionally complete food created by the North American Plains Indians. It was originally made during the summer months from dried lean Buffalo meat and rendered fat as a way to preserve and store the meat for use when traveling and as a primary food source during the lean winter months. As long as it was kept away from moisture, heat, and direct sunlight, it would last for many years with no refrigeration or other method of preservation.
Pemmican Composition: Traditionally there are a few methods of preparing pemmican. The more authentic pemmican is simply desiccated and pulverized bison/elk/deer/etc. meat mixed with an equal amount of rendered animal fat (...more fat was added in the winter months). The other version incorporates dried berries along with the meat and the fat. The addition of berries was a response by the first nations to increase the palatability of pemmican for caucasian hunters and trappers when it was in high demand by the Hudson’s Bay Company. However the addition of berries increases the chance of spoilage and detracts from the functionality of the food.


Nutrition of Pemmican: Pemmican is a nutritionally complete food. There are many reports of individuals living solely off of pemmican for years!
Macronutrients These are the main calorie supplying nutrients: Carbohydrates, Fats, and Proteins. They respectively supply 4, 4, and 9 calories per gram.
1 days supply of pemmican (~1.2 lb) supplies ~ - 0 calories from carbohydrates (0g) - 4050 calories from fat (450G) - 384 calories from protein (96g)
Total calories = 4434
Carbohydrates: You might be wondering, what about carbohydrates? Don’t we need those? Fascinatingly no! In fact the human body can undergo a metabolic shift and switch from using carbohydrates to using fats as a primary fuel! This state of metabolism is called ketosis. More on this later...
Fats: During the trip we will be quite physically active and a caloric need into the 4,000’s isn’t unheard of. As you can see fats are almost twice as calorically dense as proteins or carbohydrates. This makes fats a supreme source for energy with just short of a pound supplying almost all of the days calories. An amount of potatoes supplying the same amount of calories would weigh almost 10lbs!
The type of fat used in pemmican is also of great importance. The tallow or fat of grassing animals is composed of ~50% saturated fat, 42% monounsaturated fat, and 8% polyunsaturated fat. Saturated fat, living up to it’s name, is ‘saturated’ meaning that the fatty acid chains fit nicely together creating a denser fat which is solid at room temperature. The more saturated the fat the more easily it resists rancidity through oxidation.
There is also a major difference in the fatty acid profile of grain-fed vs grass-fed animals. The grass fed animal fat is between 25 and 50 percent healthy Omega 3 fatty acids. The grain fed animal’s fat is only 2 to 3 percent Omega 3. Omega 3 fatty acids are one of the three essential fatty acid groups contained in tallow and they are critical to the development and maintenance of our brain and nerve tissue.

Protein:
Protein is comprised of amino acids which the body uses to repair and build new tissues. The RDI, or recommend daily intake, of protein ranges from 0.6 - 1.0 g/lb lean body mass. The protein needs vary between each individual and even in the same individual depending on levels of physical and emotional stresses.
In my case, due to my metabolic shift into the ketotic state, over-consuming protein will have negative effects that could impact my ability to properly assimilate the nutritional value of pemmican. So protein will be kept at a ‘just enough’ level.
In my particular case:
Body weight is 178 lbs Body fat % is 10.0
So Lean body mass (total mass - ~ fat mass): 178 - (178 x 0.10) = ~160 lbs
At 160 lbs lean body mass my protein requirements should be:
160 lb x 0.6g protein / lean lb body weight = 96g protein
Micronutrients: The nutrients which act as the coenzymes and activators for different enzymatic processes in the body.
Raw meat contains every nutrient required for human life in varying amounts. Concerns regarding vitamin C have commonly been raised, however if the temperature at which the meat is dehydrated stays below 120 degrees then the vitamin c naturally in the meat tissue remains intact.


Metabolic Ketosis
When dietary carbohydrates are restricted to <50g/day for a period of 6-8 weeks something miraculous happens. The body shifts it’s entire enzymatic system that had previously been based on metabolizing carbohydrates into a state where it efficiently metabolizes fatty acids. This state is called ketosis.
What this means in the context of the trip: When one is in a state of carbohydrate metabolism their bodies are unable to quickly and efficiently access the vast reservoir of stored calories in stored body fat. A skipped meal or over-exertion can leave one feeling faint and chilled. This is potentially deadly in cold temperatures as low blood sugar will cause the body to decrease it’s metabolism. This decreases the activity of what is called ‘brown fat’, a heat producing fat tissue in the body. In contrast while in ketosis one can access their internal stores of body fat immediately and meal time simply becomes an opportunity to fill up the tank to full capacity. It is a truth that reminds me of the adage ‘eat fat to burn fat’ and in reality that is exactly how it works.
My Transition Period: For a 6 week period before the beginning of trip I began the process of weening my body out of carbohydrate metabolism. Though it was an easy enough process, it is not something that I would like to do in the bush. The beginning transition period can leave one feeling flue like symptoms as the body struggles to readily oxidize fats as its primary fuel. After a few days however the sluggishness disappears and steady energy replaces it.
There is a device called blood ketone meter, which is similar to a blood glucose meter. It measures the level of ketones in one’s blood to help them asses their personal level of ketosis. This is a snapshot of my ketone level on Jan. 18th 2014. It shows a level of 3.1 which is quite high. As the chart below shows an optimal ketone bandwidth is from ~1.5mml to 3.0 mml. Over 3.0 mml one begins to get into starvation ketosis and this is a state achieved during fasting; this is not something we are after if we want to maintain our strength and body mass.


The Process:
Step 1: Render the Tallow!

Cut the tallow into pieces about an inch squared. This allows a greater surface area for the heat to extract the fat. Place the un-rendered tallow into a crock pot on low heat and let simmer for 10 hours. When fat is done rendering strain off the crackling and store until step

Step 2: Prepare the Meat!
Remove all fat from the cut of meat
Step 3: Slice the Meat! Use a slicer or a sharp knife and slice the meat as thin as possible. It helps if the meat is slightly frozen as it is easier to position and hold onto.

Step 4: Dehydrate the Meat!
Place the meat into a dehydrator for a minimum of 48 hours to ensure all moisture is removed. The slices should crumble not bend when touched. One could could also add an additional step of smoking the meat for 2-4 hours before the drying process. This actually helps the longevity of the meat as the anti-bacterial & anti-fungal essential oils in the wood smoke are imparted into the meat. It’s critical in both cases however to maintain a temperature of ~ 120 degrees or less. Higher temperatures degrade the nutritional value of the meat.
Step 5: Grind the Meat!
Traditionally this was done by hand with a mortar and pestle, but the vita-mix does a hell-of-a job!

Step 6: Mix Ingredients!
When meat is dehydrated is actually loses about 4/5th of it’s weight. Much of this is water and when meat is fully dehydrated it’s almost completely pure protein! As I mentioned before, my daily recommended amount of protein, based on my lean body mass, is 96 grams. So:
96g dried x 5 = 480g of fresh meat or about 1 lb.
This means for the trip of ~ 46 days, ~ 46 lb of meat was dehydrated to only ~ 10 lb!
Each 96 gram portion of meat is mixed with 450 grams of rendered tallow. This equates to about 4050 calories.
At 450 g / day for 46 days, this equates to about 45 pounds of tallow!
It’s incredible how nutrient dense pemmican is when you really crunch the numbers!

Step 7: Prepare into Blocks
Set the homogenized meat & tallow mixture into bread pans with a tin foil coating and let cool. As the mixture cools it will harden and when it has hardened enough to remove from the mold in one piece it is time to cut into blocks. Weigh out each molded block and cut into sections of 450-530g each.
