If you’re a climber then maybe you already know but, Val­ley Upris­ing, the new doc­u­men­tary from Sender Films has been select­ed to be the fea­ture film of the 9th annu­al REEL ROCK Film Tour — and for good reason.

The trail­er show­cas­es how the film uses dig­i­tal­ly remas­tered climb­ing footage from the days when Yvon Chouinard, Roy­al Rob­bins, and Lynn Hill were set­ting unprece­dent­ed new routes on some of the most icon­ic fea­tures in Yosemite Nation­al Park. It tells the sto­ry of these soci­etal out­casts and how they defined them­selves, and the sport, through their impres­sive feats.

It’s a doc­u­men­tary that cap­tures the leg­endary era and explains how it led to the mod­ern era of climb­ing in The Val­ley, where mod­ern ath­letes like Dean Pot­ter and Alex Hon­nold are con­tin­u­ing to push the lim­its of what’s pos­si­ble on the rock.
