The climb to the summit of Mount Everest in the Himalayas has always been a dangerous one, but the last week, embodied in one viral image, has been a particularly deadly stretch atop the world’s highest mountain.

In a photo (above) released by climber Nirmal Purja’s Project Possible expedition, dozens of bundled-up climbers line a ridge near Everest’s summit, huddled against the wind and cold awaiting a chance to stand atop the mountain’s highest point. It’s a startling sight for those familiar with Everest climbing — the lineup represents a treacherous trend atop the mountain.

This overcrowding, prompted by a brief window of good weather and a record number of government-issued climbing permits, has proven deadly. Robin Fisher, a British climber whose death was reported Saturday, was the 10th climber in a seven-day span to die near Everest’s overcrowded summit. American climber Don Cash, 55, was among those who perished atop the mountain in the past week.
