Very interesting readings. Thank you for the information and time to respond. On my last attempt at Whitney, a ranger pointed me to the creek flowing straight out of the mountain by outpost camp and said he never filters there. So I didn't either and was fine. I would be a bit more hesitant about the switch back water but it sounds like many people drink it and are fine. Like always, I will be wise about the look and area prior to drinking it. Excited for some fresh mountain water.
Thanks again,
Cody
