The Diamond

The Diamond is the steep, high alpine face on Long’s Peak in Colorado’s Rocky Mountain National Park, and it is approached as an alpine big‑wall objective where mixed ice, snow and rock moves all intersect. Climbers come to the face for long, committing lines that require route‑finding, solid mixed‑technique and the ability to manage bivies and storm exposure on a high wall.

Push the Lines - Three friends. One winter line. Years in the making. follows Jesse Huey, Matt Segal and Quentin Roberts through several seasons of attempts on a single winter mixed free line on the Diamond. Shot and edited by Jon Glassberg, the film documents the team’s incremental progress: approach storms, high‑face bivies, intermittent success on mixed sequences, and the physiological toll of winter big‑wall work (the editors include repeated moments the team refers to as “screaming barfies”). The film frames their effort as a multi‑season commitment, showing how mixed tools, strap management and precise rock moves must all be combined to free a winter route on a high face.

What the film offers viewers is practical insight into the particular grind of winter alpine big‑wall climbing: how teams stage attempts, manage weather windows, and translate mixed‑technique training into on‑route progress. It’s a focused record of the logistics, route‑finding and team dynamics that shape a single, years‑long objective on one of North America’s most committed alpine walls.
