Eight skiers have been found dead, and one is still missing, after an avalanche in the northern California mountains, authorities have said. The avalanche hit the Castle Peak area of Truckee in California about 10 miles (16km) north of Lake Tahoe, at around 11.30am local time on Tuesday. The cascade engulfed a group of backcountry skiers, with six people being rescued after they became trapped. Datawrapper This content is provided by Datawrapper , which may be using cookies and other
