Ending notes on the JMT...

15/9/2016

In terms of consumables, we used 116 ml of white gas fuel per day, 70% of the planned 167 ml per day. We could have lightened the load by 1/4 of a gallon of fuel.

We also brought 2 lbs of food per person per day, but ate 1.2 lbs per person per day, 60% of what we brought. I think we could have rebalanced the food to have more breakfast and more dinner and less trail snack/lunch stuff, but obviously we could plan on 1.5 lbs per person per day, which could have lightened the load considerably. Our 16 lbs goes to 12 lbs, a significant reduction.

From Stephanie's watch statistics:
We averaged 2 mph when we were hiking, and 7.4 hours of hiking per day, with 1.24 hours of stops. 

The total elevation gained was 19,304' and lost 15,762' with a net elevation gain from Yosemite Valley of 3,542'.

The watch tallied 110 miles, where as the "official" distance is set at roughly 90 miles.

To do the entire JMT at this rate requires 105 hours, and two weeks at 7.5 hiking hours a day. So perhaps we weren't so slow, if the trail is 22% "longer" the two week trek would require 9.2 hrs/day of hiking. 

Continuing on the trail from Edison Lake, we have 120 miles to do, just scaling from this trip we'd take 9.3 days. Food for 10 days would weigh roughly the same as we had for 7 days.

Stephanie thinks that our JMT "t-shirt" should say "More Switchbacks!" 

In recognition that the modern Army marches "on its batteries" we had two batteries to recharge the various devices with: the battery from the "Goal Zero" solar panel, and one larger battery (with a small panel for trickle charging). The "Goal Zero" panel worked well and charged the batteries during the day hiking. We'd leave the second, heavier battery at home on a multi-day backpack next time. It's probably more appropriate for the weekend trips.

While I didn't think the foldable bucket that Steph brought was needed, it was in terms of managing washing, where water could be scooped and used and dumped away from water sources. 

But going planning next time will definitely focus on reducing weight.

Ray Jardine has been whittling down the ounces on just about every piece of gear. You may want to review some of that before your next trip.
Interesting anecdote about electrolyte imbalance on earlier post.
Hope to chat about it at Facelift.
