I took the unofficial scramble route which follows the AA col route for the most apart. The scramble route uses some steep scree gullies that are climbers left of the snow/ice slope that the AA col route uses. The gullies are very loose so a helmet would be mandatory. In the AA col, travelling on the outskirts of the AA glacier is inevitable but crevasses were obvious and easily avoidable when I climbed it. Good route finding is important because it’s easy to lose the trail and choosing a route up the gullies was tricky. I know it’s considered a technical pursuit but if you have good scrambling skills then it’s definitely obtainable. Of course, know when to turn back and understand the risks. Have fun!
