Ground Truth Trekking is based on the belief that expeditions to see what's on the ground help us learn about important issues. We combine that "ground truth" with "researched truth," using our scientific backgrounds along with our adventures to come up with something we hope will further the conversation about these issues in an entertaining and informative way.

In addition to our ongoing expeditions, we're working on a number of projects to spread information about natural resource issues in Alaska.  If you like what we're doing, please support our expeditions and our work!
