First day of field testing. Weather is perfect – sunny, very few clouds with temperatures between -10 and -15C. All necessary equipment is carried on our backs up a hill to a frozen lake which informally goes by Lake Potentilla from where we get spectacular views of the surrounding area (even a glimpse of the glacier). At the lake, Seth, Jeff, Amy, and Sarah work on deploying sensors at various depths after successfully drilling through the ice to liquid water. At the same time, the rest of the team drill a “sniffer” hole and tap it off for gas to accumulate from a rock formation at the lakes edge. We then go for a short hike with Lisa to collect gas samples from few previously drilled sniffer holes in the vicinity of the lake. The day is a success and everyone is content.
