Long, busy beach near Boston where harbour debris gets trapped and sea glass turns up in the pebble piles after rough weather.
Spectacle Island in Boston Harbor served as the city's rubbish tip for decades before it was capped and landscaped into a park. The sheltered harbour waters now wash a steady stream of old glass and ceramics out of the island's fill and onto its beaches. It is reached by a seasonal ferry from Long Wharf.
Plentiful glass, including pale green Depression-era pieces, along with willow-pattern china and cup handles. Many pieces are only lightly frosted because the harbour is calm.
