Two climbers chose an ambitious line to tackle. It’s long, logistically challenging and comes with plenty of unknowns. It also happens to be in a grove of trees. Directed by John Waller (who brought us Into Darkness in 2011), Treeverse features Brian French and Will Koomjian as they attempt a 1-kilometer transect through a grove of oak trees in northwest Oregon. The tree climbers eat, sleep and live among the branches as they move through the canopy — facing nasty weather, technical challenges and large gaps in the line as they pioneer a new method of getting from point A to B.
