As for the water purification tablets, we never ended up using them. The water in the steams was so cold that any time the water ran over a rock or a piece of wood it would freeze into a big icicle. So we figured it was probably pretty clean if it was that cold and took our chances.

I really enjoyed this hike in the shoulder season since the bugs are non-existant and hiking in cooler temperatures is much easier, especially on the uphill. The daytime high was somewhere around +10 to 15C and on the second night it went down to at least -10C. It was pretty frosty in the morning, and there was lots of condensation frozen inside the tent but my new MEC Hybrid -20C bag worked well. It was so toasty you could probably bake cookies in it.

The Rockwall trail itself was spectacular, and now I can definitely see why it’s one of the most popular trails in Canada. The huge limestone cliffs were impressive and made all that much better by the thin layer of fresh snow up high. The longest day was 21km and although it was supposed to be quite difficult it didn’t seem bad at all since there was only two of us we could keep a steady pace and the air was nice and cool. The sudden temperature changes between the sunny and shaded areas was pretty remarkable. In the sun the ground was soft and muddy but in the shade it was frozen solid and the air was easily 15 degrees cooler.

Since I forgot to bring a camera here are a couple shots from other people of the Rockwall from flickr.com: One,Two, Three

The first shot is actually of the Floe Lake part of the trail that we weren’t on, but it’s very similar to what you see later in the trail. The second shot is again nearer to Floe Lake than we were but still very similar. The last shot is exactly what we hiked, you can see Rockwall pass off in the distance and the alpine meadows that we hiked after the pass. There is also a very impressive lake hidden just below the shot.

• Effective against Viruses, Bacteria, Giardia and Cryptosporidium - Good, same as the drops
• Improves the taste and odor of treated water - I don’t know what could take better than a mountain stream but I guess that can’t hurt…
• Easy-to-use tablets - Excellent! The reason I’m buying these.
• Meets EPA microbiological water purifier tests - Not sure what these tests are, but it’s the EPA they must know what they’re talking about right?
• […] the safe choice for campers, hikers, […], and anyone needing to drink water of questionable microbiological quality - Hikers eh? Sounds good.

Now, apon opening the packaging there are 30 individually wrapped foil packages. They seems to be no easy way to open them other than a knife or scissors (or your teeth! but you’ll see why that might be concerning in a second).

The only information on the inside of the packaging is the times required to kill certain bacteria and viruses and a small note called “Precautionary Statements” and “First Aid”. The First Aid bit seemed a bit odd at first, but after reading the precautionary statements it seems less out of place. Here is the Precautionary Statements verbatim:

Precautionary Statements
Harards to Humans and Domestic Animals
DANGER. Corrosive. Causes irreversible eye damage and skin burns. Harmful if absorbed through the skin. Harmful if swallowed. Do not get in eyes, on skin or on clothing. Wear protective eyewear (goggles, face-shield or safety glasses) protective clothing and rubber gloves. Wash thoroughly with soap and water after handling. Removed contaminated clothing and wash before reuse.

WTF?! Harmful is swallowed??? Maybe I should take my chances with the giardia then! And they expect me to take protective eyewear into the mountains with me? Hah! Of course this is just the lawyers being careful, but still….

I’m glad the parks people were kind enough to post this sign at the END of the trail - after we ‘misplaced’ the trail a few times over that last 14.5 km

However we did survive and I’ll be posting a much more detailed trail report in the next fews days, complete with gobs of stats. But here are a handful of photos in the mean time:

Silver Lake in the morning light - our first campsite.

Mill Creek Pass - the 2nd pass on this trip and probably the easiest - you’ll note we’re actually smiling in this photo.

Top of Speculator Pass - WOW, they said it was steep but I didn’t think you could actually call a 60 degree slope a trail! I’ve never hiked anything this steep before but it was definitely worth the view.

So Aidan, Mike and I are leaving for our 7 day backpacking trip to the Absaroka Wilderness Area about 46 miles south of Big Timber, Montana. Among the time planning for this trip more than half of it was dedicated to coming up with a way to get enough palatable calories each day. While we decided that our meals would be individual this year instead of sharing a pot - forcing us to all eat the same suppers – we ended up packing very similar food. Here is a run down a daily ration of the food I’m taking on this trip:

Breakfast
Instant Oatmeal - 360 cal
Myoplex Protein Shake - 280 cal

On The Trail
PowerBar ProteinPlus - 300 cal
(2) Clif Bar - 500 cal
King Sized Snickers - 520 cal
Nature Valley Granola Bar - 220 cal
Sun-Rype Fruit Bar - 120 cal
2L Gatorade - 520 cal

At Camp
Endurox R4 Recovery Drink - 270 cal
(2) Ichiban Noodles - 780 cal
Lipton Pasta or Rice Dish - 560 cal
Hot Chocolate - 200 cal

Total Daily Caloric Intake: 4,630

Now according the various online caloric calculators someone my size, age, and height should need between 6,000 - 7,000 calories per day for 6 hours of backpacking. Taking an average of 6,500 calories burned each day that means there will be a 1,870 calorie deficit each day. Over 6 days that works out to a total deficit of 11,220 and since 1 lb. of body fat is 3,500 calories it is a good estimate that I will need to burn 3.2 lbs of fat over the coarse of the week. We’ll see….

Again I was wearing my heart rate monitor to keep an eye on my heart rate on different terrain and to keep track of calorie consumption. I also took the footpod along this time to keep track of distances but I don’t think it was very accurate. Either because the stride length wasn’t consistant enough, or that it wasn’t calibrated for a walking pace, or the regular stops, or more likely a combination of all those factors. However, it should have hopefully been consistantly inaccurate and thus a somewhat fair judge of distance.

I also tested out using protein shakes and recovery drinks to increase daily calorie consumption and recovery. While the recovery aspect is almost impossible to quantify it doesn’t really matter to me because to me it felt like it was making a difference. Especially the Endurox immediately following the day’s hike. I’m quite aware that it is mostly likely a mental preception but I will say that I didn’t feel as much muscle stiffness and had more energy a few hours after making camp for the day than I remember on past backpacking trips. In addition to the Endurox I also consumed a Myoplex protein shake/meal replacement every morning after breakfast. This seemed to give me a good start to the day and on the last day I even skipped breakfast in favour of only the shake. As a result I’m planning to take only a Myoplex for breakfast on at least a few of the days on the upcoming Montana trip. One thing I didn’t learn about a shake for breakfast is it’s much better to mix the powder in a small Nalgene the night before as it’s really a pain to get it fully mixed without big dry clumps when it’s cold and you’re half asleep. The only change I’m planning to make to my menu after this trip is to vary the pasta dishes with some instant rice dishes and to take at least 2 litres worth of Gatorade powder per day to increase my daily intake by 500 calories and keep a constant supply of quick carbs for the steap uphills where it’s difficult to eat anything without losing your breathing rythmn. I also took Cliff Bars on this trip instance of ProteinPlus Powerbars. They seem a bit more like real food compared to the super compressed Powerbars, but I think I’ll take a combination of both in the future as they were both good. Mike on the other hand couldn’t seem to be able to choke one down even when he really needed to - so I hope he finds some high calorie food that he can pack down for 8 days pretty quick. This trips daily calorie count was 3200 cal/day and I was easily eating the entire extra Ichiban that Chantal didn’t eat on two occasions.

Here is the heart rate monitor data for the trip:

Day 1: Emerald Lake to Yoho Lake
Distance: 8.0km [map] | 6.9km [monitor]

Day 2: Yoho Lake to Twin Falls
Distance: 13.5km [map] | 11.25km [monitor]

Calories: 1167

Day 3: Twin Falls to Yoho Lake via Whaleback and Iceline Trail
Distance: 18.5km [map] | 17.6km [monitor]

As usual there are many more photos posted in the photo section.

Now if only you could download the full maps like USGS allows in the states…

Update:
After reading the License Agreement for Digital Topographical Data it looks like there is no reason I can’t post a copy of the Yoho National Park topographical trailmap I put together.

So here it is:
Yoho National Park of Canada - Free Downloadable Topograpical Trail Map - Scale 1:40,000 (hint hint Google…)

Update 2:
Might as well post one for Kootenay National Park aswell.
Kootenay National Park of Canada - Free Downloadable Topograpical Trail Map - Scale 1:40,000

Day 1: 6.6 km
Numa Creek - Gradual uphill - 1 hour 55 minutes - 750 cal

Day 2: 7.1 km
Tumbling Pass - Approx. 1330 ft elevation gain - 3 hours 51 minutes - 1713 cal

Day 3: 9.3 km + 16.8 km
Tumbling Creek - Mostly downhill - 3 hours - 1000 cal
Helmet Creek Loop - Approx. 800 ft elevation gain - 4 hours - 1934 cal

I think most significant is how much slower we were moving with any serious elevation gain. Next trip with the footpad I’ll be able to see what our actual speed is.

By using these maps I’ve put together an approximate elevation gain/loss chart for the trail. You can clearly see the 3 passes that we’ll have to do. I think the most surprising part is how high the passes actually are. The first and last pass we have to do almost hit 10,000 ft. In comparison the 1 pass that we did last time we went to Montana was only 8600 ft. So basically I’m going to be sucking wind - being that the elevation of Regina is only 1893 ft.

UPDATE:
Elevation gain per day is approximately as follows:
