Micah Gammons, a licensed blaster with Caltrans, has gotten a lot of practice blowing up boulders recently.
Last year, there were the 300-ton granite boulders that rolled onto Highway 1 in San Luis Obispo County. Now, he’s busting sandstone boulders bigger than an SUV in Montecito.
“We usually do one to three blasts a year,” said Gammons, the District 5 maintenance superintendent. “This year…we’ve done well over 30.”
A dozen of those explosions have been in Montecito, where a Jan. 9 storm dumped 25% of its water in a single five-minute span. The deluge turned fire-ravaged hillsides into rivers of mud, trees and massive sandstone rock.
