I am just a hiker/backpacker, not a technical climber. I've heard that Middle Sister is a non-technical climb this time of year, can any one give me some info. about climbing from Obsidian TH, which I want to do next week? We will probably just take our time and camp up near Obsidian Cliffs somewhere, maybe Sunshine Meadow, and try to summit the next day. I have summited South Sister in the past and found it strenuous, but not bad really. I didn't have to walk on any snow, which I prefer since I have no cramp-ons. Any info. would be greatly appreciated. Thanks.
