This is typical disision at the field that so many unkown factors we could not prepare all! Our final goal is drilling 3-5m deep at potential permafrost side higher than 5300m. I already lost two diamond bits by hard rock. Hand drill is nice to light weight for high altitude clibming but hard to oprerate!! Peruvians everybody hate this sytem. So only the option also avalable at Arequipa town is back to electric drill. We can buy easy SDS-plus drill that I brought adapter from Alaska. For the generator, that is tricky because air is almost half in Fairbanks. 1kw generator can run at 5000m but also half or less power. So I brought Botch SDS-plus hammer drill (800W). We need more than 2kw generator. We decide to bring 5kw!!!! That is crazy almost 100kg(200lb) need lift up!

They are strong!

even for them, mission is not easy for many reason. One of them, we are not normal climbing route. No trail system makes 10 times (maybe 100 times) difficult to carrying up someting!

Tropical sun is stright to down! so this meas dark quickly! we should stop today.

The way back to the car, Misti already had beautiful moment!
