If you go: How to find sea glass
Where to look in Maryland
Head east. The Chesapeake Bay's eastern beaches are better than those on the west side, but local collectors have found good pieces where the Potomac River empties into the bay.
Do research. Check with local historical societies to find towns, ports or docks that were active 50-100+ years ago.
Pay attention to prevailing winds. Shorelines that receive those winds will normally produce the best sea glass.
Check nautical charts. Find where shipping channels come close to shore or where small boat traffic is active.
When to look
Between late fall and early spring, when the sun is closer to Earth than it is during hot summer months, which increases gravitational effects and more dramatic tidal changes.
Generally, low tide and especially the first low tide after a storm that has on-shore winds of at least 15-20 knots. When on-shore winds peak during a high tide that coincides with a full moon or new moon, the surface area of the beach covered by water will be at its highest level. This is a "spring tide," and the high tide will be much higher than usual and the low tide much lower than usual. To determine the next spring tide and other lunar influences, go to noaa.gov.
What to bring
Warm clothes. The weather at shoreline can be considerably colder because of wind, so dress in layers.
Containers. Bring something to hold what you find. My sister uses leftover Cool Whip containers because they're sturdy and the white background picks up pastel tints. I use two zipper plastic bags, one for "special" pieces.
Gloves. On cold days, I take thin vinyl gloves, which fit over knit gloves and allow me to sift through sand and pick up pieces without getting my hands wet and sandy.
