US EditionPredicting deadly rockfall would have been impossible, say geologists
- A deadly rock slide occurred on Thursday near Bow Glacier Falls in Banff National Park, killing two hikers and injuring three others.
- The rock slide resulted from water seeping through rocks from a lake above the cliff, which has existed since 1955, eventually dislodging a boulder.
- Observers heard vibrations and saw rocks shifting before a large section of the mountain dislodged, causing boulders to tumble down onto hikers near a well-known trail in a picturesque location.
- Experts, including Clague and Shugar, said predicting exactly when or where rockfalls will occur is impossible and rock slides like this cannot be stopped.
- Officials and experts suggest posting notices warning hikers to minimize time spent in the area and avoid standing under slopes to reduce risk from unpredictable rockfalls.
