Working out how to do it

Ventured a bit further afield today, about 100km to the north and a bit less then that to the south. Did a fair bit of back-tracking, seeing what works, what doesn't, and trying to identify the energy lines. The Andes are a very significant mountain range; about 100km from here is a peak of 7000 metres. We are really only fooling around in the foothills, little things of only 3000 metres or so high. But therein lies one of the difficulties of this place. A lot of the bits we are flying over look like hills; they are quite shallow and almost flat on top. The photo below taken at 8500 feet sort of demonstrates this:

It is quite tricky working over this sort of stuff. Mostly it is just anabatic lift so we are quite close to the terrain most of the time. It would be easy to become unstuck if you aren't paying attention. The whole task area is an eerie moonscape. It all looks utterly forbidding. I am treating it with great respect.

My oxygen bottle is still lost. I suspect I may never see it again. One of the locals has kindly lent me a bottle so we will get that fitted this evening. Otherwise, all good.
