It's not the MOST epic, but definitely the most memorable. I was on one of my last days in Patagonia and I had two days to kill with good weather, so I went for a split mission to Refugio Frey. I couldn't find anyone to go with me so I decided to go it alone, which I now know was totally stupid. I split to some lines and lapped solo all day, but decided to exit early as I got my fill and the snow was going bad. The exit was not what I thought and I took the wrong route and ended up in some sticky rock climbing situations hiking with my split board on my shoulders. I made it out just before it was too late nearly missing some slide for life scenarios. In hindsight, this was actually the best thing I could have done as I learned important lessons about ego, backcountry travel, and what NOT to do. I did manage to ride a few life-changing lines that day...!
Going deep into the Crazy Mountains of Montana with Jeremy Jones and Mark Carter for TGR's Far Out is also right up there with my most memorable backcountry experiences. That was a wild adventure and I learned a lot!
