Ben Nevis Observatory snow depth

From 1883 to 1904 scientists lived and worked year round at the summit of Ben Nevis - observing the weather at 1,343metres (4,409 feet) above sea level was an extreme task. One winter activity consisted of digging snow holes in a competition to be the first to reach solid ground. The holes could reach 3.6m (12ft) in depth.
