#DYK 🍂 Leaves and yard waste DO NOT belong in landfills or incinerators! Compost, mulch, recycle, or use your town’s collection program. Keep leaves out of streets to prevent clogged storm drains and flooding. Pro tip: Leave some leaves on your lawn to naturally enrich the soil!

King Tides at new and full moons not only bring extreme high tides, they cause super low tides that are perfect for strolling the tidal flats. For more about King Tides, see: bit.ly/48oOV46

On October 7 on Nantucket, the Massachusetts Board of Underwater Archaeological Resources (BUAR) tagged the first shipwreck remains as part of their new Shipwreck Tagging Archaeological Management Program (STAMP). For more on STAMP, see: mass.gov/BUAR/STAMP

Through STAMP, the public can help document and monitor shipwreck sites and track remains redeposited along the coast. So, if you see timbers with a STAMP tag, please scan the QR code, fill out the form that pops up, and add a photo to record your find.

Other shipwreck remains can be reported through BUAR’s Shoreline Heritage Identification Partnerships Strategy (SHIPS) program. And while everyone is welcome to visit these exciting finds, it is illegal to disturb, destroy, or collect material. mass.gov/info-details/buar-s…

Remember the shipwreck that washed up on the south shore of Nantucket during the nor’easter? Some experts initially thought the fragments were part of the 1884 cargo ship the Warren Sawyer. Turns out, they were wrong.

If you find shipwreck remains, please report them at mass.gov/BUAR/SHIPS
Replying to @NECN
Massachuetts’ Underwater Archaeologist, David Robinson told @danreidyreports the wreckage measurements don’t match the Warren Sawyer. And from what he can tell, this newly found piece is a portion of the side of a shipping barge mostly made of hard yellow pine.

Strong wind and waves can be very dangerous, so carefully monitor your surroundings and stay safe when taking photos. And never drive or walk through flood waters! Photos you can safely submit of road flooding at high tide are particularly helpful for informing storm response.

In addition, photos of coastal erosion are also important for assessing damage and making management decisions. As always, safety first! Beware of the winds and waves at the coast, along with potential storm surge when taking photos. And thank you for your participation!
