  • Andy marks the location of a moulin with the handheld GPS. I don't know why I asked him to do this - I'm just curious and thought it might be neat to track the velocity, size, and activity of a few of them. Maybe it could lead to a paper on surface hydrology.
  • Supraglacial stream.
  • The rocks to a good job at insulating the ice beneath while the ice around them melts. Eventually they fall over.

  • Wide surface stream near the edge of the northern moraine on the main trunk of the Black Rapids Glacier. That boulder was huge, as a climber, I wish I had brought my climbing shoes and a bouldering pad.

  • Cool little canyon.
  • Water disappears under snowpack. There must be a moulin too because there was no water coming out the other side. This greatly illustrates why you don't walk on isolated snow-patches on the glacier this time of year.

  • Channel gets deeper, faster, and harder to cross.
  • We finally crossed the stream at a wide, shallow, slow moving location.
  • Small pond on the north moraine of the glacier.
  • There are numerous small ponds on the northern moraine.

  • We were walking to a pressure sensor installed in a marginal lake that is also monitored by a time-lapse camera. We are still on the glacier here, it's just covered by debris.
  • This looked like this was just ice frozen beneath the water surface, which is weird since ice floats. Andy tried kicking it to see if it was or if this was glacier ice showing through the rocky moraine.

  • We made it to the lake that had drained a few weeks before we arrived.
  • bolt on a boulder in the lake that the pressure sensor is tethered too.
