ABUBUWAN DA ZA KU GUDU DAGA WANNAN LABARI:

In October park officials permanently closed one-third of Curry Village under Glacier Point after the equivalent of 570 dump trucks of rock hit 17 cabins and forced the evacuation of more than 150 youngsters on a field trip.
A series of falling rocks, some as large as microwave ovens, tumbled at least 100 feet from the base of the cliff and into the valet parking lot, where several cars were damaged, park spokesman Scott Gediman said.
Guests of the historic 125-room hotel were directed to the south lawn behind the hotel while geologists checked the stability and assessed the likelihood that more rocks would fall.
