Despite a perilous, unstable ice block hanging over a key trail on Mount Everest, and undeterred by high costs and increased permit fees, hundreds of climbers are pressing ahead with their ascent of the world's highest mountain.
Around 410 climbers and an equal number of Nepali guides are currently at base camp, preparing for their attempt on the nearly 8,850-metre (29,000-foot) peak this month, hoping to capitalise on a narrow window of favourable weather.
