Snow was very hard, alpine ice at times, From the Teski refugio door to door it was a relaxing climb of about 10 hours. I would recommend a few pickets and screws, especially if all climbers only have one ice axe. Route up to the glacier is very straight forward. Make sure to check in with CONAF. Always helpful to show mountaineering club membership.These were the gear requirements in summer 2018..
Gorro (warm hat or hood)
Lentes (glacier glasses)
Botiquin (first aid kit)
Zapatos (boots, leathers will suffice)
Piolet (axe, at least one per person)
Cuerda dianm. (dynamic rope)
Got to see Puyehue erupting from the summit, which was cool
thought the stars had aligned when the one day I had to climb showed "sunny and clear" for the weather in an otherwise week of bad climbing weather. Hah! We made it to the top of the ski lift when the realization set in that this Eager Beaver probably wasn't going any higher today. Still, we spent a couple of hours in the "container" warming and waiting for that optimistic forecast. Qui audet adipiscitur? Hah! Dios Dice: No dice and back to Telski to warm the bones.
7am at the old ski resort parking lot, along with Ted and Toast (Ted's dog) saw our start to climbing Orsono. Hiked about 300m to glacier and out of our santa sacks came crampons, harness, helmet and rope. Snow/ice travel between 20-40 degrees until bergshrund. Crossing of bergshrund aided by snow bridge. Slope steepened to between 45-55 degrees to summit field (big enough to circle around the tree with the entire [extended] family!). Returned via the same route. Total climbing time around 4 hours.
Stayed at the refugio and finally got some beautiful weather after 2 weeks of rain. Pretty straight forward getting up, no crevasses on the direct normal route. Got within 50 m of the top when both crampons of one of our party spontaneously self-destructed. Ah well, views were great and was fun all the same. Hasta siguiente!
My brother and I were in the area and we had some Kahtoola crampons and running shoes, and light ice axes, so we decided to give this a try. Fairly straightforward, we got maybe 1-200m short of the top and judged it to be to steep to continue with our gear, so didn't summit. Took about 4 hours up, 2 down. Hard packed icy snow, the sun hits the route later in the day so probably want to start early.
Beautiful volcano. We took a variation from the normal route.
No powder snow and very icy.Beautiful views from the top.
