Lingering snow piles from the record-setting New England winter continue to plague the Boston area, even as the weather turns summer-like.

A 75-foot-high snow mound in Boston's Seaport District has been reduced to a three-story pile of dirt and trash — including bicycles, traffic cones and even half a $5 bill — that remains encrusted in solid ice.

Department of Public Works Commissioner Michael Dennehy tells The Boston Globe (http://bit.ly/1Brmvyd ) the vile pile is "a science experiment waiting to happen."

Crews have been working for six weeks to clean away the trash as it breaks free from the mound. So far, they have pulled out 85 tons of debris.

Dennehy says the pile will be around for weeks, even as the air temperature hits 80.
