Well, I guess the scale at the trailhead is mostly accurate.

When packing for my Yosemite hike next weekend I loaded it up with everything I took on my Whitney trip first and weighed it on two different scales. Came in at 43 lbs.

So the 45 lbs I saw at the Whitney trailhead scale is pretty close. And there's always the chance the food isn't the exact combination or I missed something.

Still not sure why my pre-Whitney weight came in at 37 lbs when I was packing it. I did discover that my two 32 oz Gatorade bottles were 2 lbs heavier than the two 20oz bottles I had originally planned to take (the grocery store in Lone Pine only had 32 oz bottles in Glacier Cherry). smile

So that accounts for 2 lbs of the extra weight, but not sure about what the other 4-6 lbs was.

Well, I guess I'm able to carry more weight on my back than I thought I could. smile
