Climate Science from the Roof of the World: Hari Mix’s spring collecting data for ASC in the Himalaya

Hari Mix is a PhD Candidate at Stanford University and is climbing in the Himalaya as part of a team of researchers,TripleED, who are studying decision making in high altitude environments.  Hari is collecting snow samples and lichen for two ASC projects while attempting  to summit Lhotse and East Lobuche.

From Hari:

It all started with a coffee shop conversation…”Well, we’re looking to go to Everest this spring.” A few minutes later, I sort of needed to pinch myself back to reality, “Umm, you want me to go climbing?” As an earth scientist nearing the end of my PhD in Environmental Earth System Science at Stanford, I’ve been extremely lucky to travel for my degree. My research, which focuses on the evolution of topography, ecosystems and climate over the past 65 million years has taken me all over western North America and to Mongolia twice. But I’d just been offered the opportunity to climb Lhotse, the world’s fourth highest mountain, as a researcher with on a project studying the organizational behavior of commercial mountaineering expeditions. The Extreme Environments – Everyday Decisions ( research project focuses on how organizations operate in environments where the wrong decision endangers lives. As the high altitude member of our team, I spent the spring climbing embedded with a commercial Everest operation before making a summit attempt on nearby Lhotse without supplemental oxygen.

I’ve always been fascinated with the magnitude, beauty and balance of earth processes. This manifested most obviously in an obsession with big mountains that began when I encountered the Canadian Rockies as a child. So when I learned of Adventurers and Scientists for Conservation a year ago, it was a natural step for me. Passion for nature and stewardship of our wild places are inextricably linked. ASC plays a critical role as a matchmaker between scientists who desperately need data to better understand and monitor the natural world and those who love it most. Adventurers looking for a way to add learning and a sense of meaning to their trips need look no further—ASC’s helpful staff will make real scientific work an easy and integrated component of your next expedition.

That doesn’t mean collecting data in extreme environments will be easy—in my case, it meant hauling 15 1L Nalgene bottles up to an elevation as high as Denali, then rappelling off the lip of a crevasse at 20,000ft. As a participant in a project led by Natalie Kehrwald, I was tasked with collecting a time series of snow samples in order to track the history of dust deposition from the Indian subcontinent on high Himalayan glaciers. For another of Natalie’s projects, I fought through the pain of freezing fingers and willed myself to remove my down mitts just after dawn at Everest’s camp three (23,000ft) to collect a set of snow samples spanning a range of elevations on the classic Everest route. And possibly most interestingly, I managed to track down one of the highest plants in the world—a moss growing in a small granite crack near camp two (22,000ft) and collect a sample for a group of scientists studying symbiotic relationships at high altitudes.

In late may, I made a summit attempt on Lhotse, and managed to make it to camp four without supplemental oxygen. Despite feeling physically strong and headache-free at 7850m (25,700ft), high winds and snow thwarted my summit attempt. Nonetheless, it was a magical trip and great learning experience. Thanks again to ASC everyone who supported my expedition!
