Ground Truth Trekking

Open Lead

In March, most streams and rivers are frozen, but open water patches (open leads) can form where groundwater enters the stream. These photos were compiled for a project looking at open leads as evidence of groundwater flow near the Pebble Mine Prospect in southwest Alaska. Most photos from ground-level were taken in March 2008 during our long trek from Seattle to the Aleutians. The aerial images were taken during a survey flight on 11 March 2011.
