PITTSFIELD — The task of clearing the snow from Berkshire Crossing, one of the largest retail center parking lots in Pittsfield, fell to two veteran snowplow drivers.

Armed with enormous Komatsu plows and an array of caffeinated beverages, the drivers from Bartlett’s Landscaping Design in Pittsfield began pushing snow Sunday morning and wrapped up about 24 hours later — just as another squall moved in.

Their towering piles of snow lined the parking lots.

Snowbanks lined the parking lots of stores at Berkshire Crossing Shopping Center in Pittsfield on Monday.

“We just keep on stacking them,” said Taylor Bartlett, owner of Bartlett’s Landscaping Design.

Bartlett said it takes careful arrangement to push the snow into piles.

It's like a "science," he said.

Berkshire Crossing houses nearly 20 stores — including big ones like Walmart, Market 32 and Home Depot — that, combined, comprise 447,307 square feet of indoor retail space. The parking lots take up far more space than that.

Bartlett's Landscaping Design tackled the 15 inches of snowfall across the Berkshire Crossing Shopping Center in Pittsfield with two large plows.

The storm kept would-be shoppers at bay, so the parking lots were much emptier than usual at least. Still, the lot needed to be clear in time for stores to open on Monday, some as early as 6 a.m.

The drivers for Bartlett’s are veterans of plowing the Berkshire Crossing lot.

“What better person to do it than someone who knows the parking lot?” said Jay, the driver of the other Bartlett's plow who declined to give his last name.

While plows pushed snow, Niko Martinelli, one of the retail employees, pushed a shopping cart filled with road salt. He threw salt over a few snowy parking spots and, occasionally, paused to shovel.

Taylor Bartlett, owner of Bartlett's Landscaping Design, shares his "secret" for pulling off a 24-hour snow plowing shift: a blast of caffeine from a Monster Energy drink.

Despite the conditions, Martinelli said he didn’t mind the task.

“I lived in Alaska,” Martinelli said. “I hate snow, but the cold doesn’t bother me.”

Several storefronts away, Jennifer Goodnow, an employee at one of the coffee shops, reflected on the difference in extreme weather between the Berkshires and her former home in Florida.

There, it was “hurricanes and rain,” Goodnow said. “Here, it’s snow and ice.”
