Methow Valley Mystery LAKE Hike Number 1

Last weekend August 19, 2012 it was blazing hot, I mean triple digits hot temperature wise, but my youngest daughter was visiting me and we were excited about hiking somewhere in the North Cascades.  So we decided to go to a local Winthrop Washington favorite lake hike on this sweltering hot day.  The video has some hints for you of where this great little mountain lake is.  Can you guess where we were?
