Two climbers who are attempting one of the most difficult rockfaces yet to be scaled are two or three days away from reaching the top.

Tommy Caldwell and Kevin Jorgeson are nearing the top of the 900m unconquered side of El Captain in Yosemite National Park.

The climb's media manager, John Long, told Today there was a "huge crunch now" as network television from around the world had started "pouring in" to Yosemite National Park.
