Lost water purifier at Obsidian Trail October 19-20 2013

[Miekje]

My boyfriend and I camped at the Obsidian trail in the weekend of 19 and 20 October. We think we left our water purifier at our camping spot. We camped along the climbers route to Middle sister, a couple of hundred yards from the crossing with PCT. On the right of where you cross the creek moving towards Middle Sister (just before the steep part to the 'saddle'), on a little outlook, right below the ridge below Arrow lake. It's clear from all the footprints that somebody camped there. Anyway, hope it makes sense. I hope anyone had found the water filter or maybe if you intended to hike there please have a look. It's in a black pouch, on the obsidian, probably the reason why we left it . Thanks! Happy hiking! Marieke
