Seattle: Alki Beach glass drift

Where: West · North America · approx. 47.58, -122.41 (vicinity only)

Why this spot: Seattle's founding beach (1851) and century-old amusement shore, its Puget Sound drift still recycling city glass onto the sand

What turns up: craft-grade frosted whites, browns, Coke-bottle greens, insulator blue, rare lavender, sea pottery, agates

Access: Open / legal.

Public city beach: surface-picking sea glass is fine, no digging into banks; note the offshore cove is a WDFW marine preserve for marine life, glass picking on the beach itself is unaffected
