What can be done to prevent massive rockslides like the one that closed down a stretch of I-70 Thanksgiving morning?
Nothing say geologists.
They say the state's rocky, steep slopes make it dangerous for drivers to go through mountain passes. And they add chances of drivers being hit by falling rocks are more likely with more cars on the roads.
C-DOT spends about $1.5million every year in measures such as angling slopes less steeply and planting vegetation to catch falling rocks.
But the geologists say rockslides, although rare, are impossible to prevent.
