“On the west side of Market Street, Route 136, near the Swansea-Warren line may be found King’s Rock on Sachem’s Knoll where Indians from all over New England used to celebrate their victories in tribal wars and talk about their peace treaties.” [from The Swansea Stage Coach, 1976] Geologists Otter Brown and Dan Lanier from the Rehoboth Land Trust decided to get a closer look on January 30, 2024.

(Above) Otter and Dan first examined King’s Rock on the west side of Route 136, a large bedrock outcropping at the top of a rise just south of Johnson’s Roadside Farm Market that features a descriptive marker placed in 2023.

(Above) Otter examines a rock at the southern end of King’s Rock to see if it might be part the same rock before crossing the street where he and Dan examined the glacial erratic boulder that sits atop another bedrock outcropping called Sachem’s Knoll.

(Above) After examining the boulder and determining that it is made of puddingstone, a type of sedimentary rock which was formed millions of years ago when silt was compressed with smaller rocks and pebbles embedded within, Otter and Dan examined a large rock outcropping just south of the D’Allesandro Farm that appears to be part of the same line of outcropping rocks.
