Once on the glacier (Mer de Glace) it is several kilometres walk to some more ladders, to get off the glacier and up the path to the Courvercle Hut below the Aiguille du Moine. The glacier is ’dry’ this low down at this time of year so is mostly easy to walk on - you can see the objective dangers (crevasses) and avoid them. A refreshing cold breeze blows down the valley, otherwise it would be hot under the summer sun.

Way back when, a person could stop by Chris Wright’s place in Hot Springs and go through a bin with boulder opal rough. It was sold by the pound. That was okay because about 99.99% of it was ironstone matrix. I suspect that possibly as many as a dozen people have high-graded it before it got to the bin but every now and again Chris would put back a piece for that special person. Unfortunately, more often than not, I was usually not that person. (Author: Don Lum)
