The Abner Concklin House (also known as Old Yellow House) is a historic house located at Closter Road in Palisades, Rockland County, New York.

Concklin-Sneden House is located in Rockleigh, Bergen County, New Jersey, United States. The house was built in 1796 and was added to the National Register of Historic Places on January 10, 1983. Built about 1796 by Jacob Concklin, Jr., a "wheelwright", the house is an example of Dutch Colonial architecture. Erected on the site of an earlier Conklin homestead, it stands on a 166 ½ acre farm purchased in 1748 by Jacob Conklin, Sr. Later owners, all descendants of Conklin's, were the Samuel Sneden and Samuel Beasley families who lived here until 1902. The house since has been enlarged and remodeled. The dwelling is a spacious, rectangular, five-bay, 1½ story gambrel-roof sandstone structure. The architectural style is "Dutch Colonial" with a gambrel roof. The side and rear walls are the original. The exterior sandstone front wall was refaced circa 1961. A small one-story sandstone wing on the south side of the main structure houses the present-day kitchen. A similar sandstone wing on the north side has been converted into a garage.The front door opens into a center hall which traverses the dwelling to a rear door. There were one or two rooms on each side of the center hall. The main floor includes living room, dining room and small rear chamber. The garret above is finished into four bedrooms and two baths. The house has its original floorboards. Above the eaves the gable ends are clapboard. The large open garret was divided into rooms. Later alterations include front dormers, additional windows on the front facade, exterior chimney, and a full-length rear shed dormer.The cellar, fully excavated, was another large, open space and at each end were stone arches to support the weight of the fireplaces and chimneys above. Access to the cellar, for storage of crops, was by way of two outside hatchways (since removed) built into the front foundation.The present south wing is a modern addition that partially stands over a previous smaller wing (possibly dating to circa 1750) of which only he cellar excavation remains. The original small wing may have served as the kitchen for the main house. This small wing also may have been the older original structure before the main house was built circa 1796. Sited in an easterly direction on two acres of land on the west side of lower Rockleigh Road, the dwelling is in good condition. In recent times, the facade was altered by placing three windows at each side of the entrance. In addition, the sandstone wall was refaced, probably "in situ", from the usual smooth dressed stone to what is now "rock-faced". Roof dormers were added as well as a rear addition which widened the original structure.

The Tappan Zee (; also Tappan Sea or Tappaan Zee) is a natural widening of the Hudson River, about 3 miles (4.8 km) across at its widest, in southeastern New York. It stretches about 10 miles (16 km) along the boundary between Rockland and Westchester counties, downstream from Croton Point to Irvington. It derives its name from the Tappan Native American sub-tribe of the Delaware/Lenni Lenape, and the Dutch word zee [zeː], meaning a sea.Flanked to the west by high steep bluffs of the Palisades, it forms something of a natural lake on the Hudson about 10 miles (16 km) north of Manhattan. Communities along the Tappan Zee include Nyack on the western side as well as Ossining and Tarrytown on the eastern side. It was formerly crossed by the Governor Malcolm Wilson Tappan Zee Bridge, opened in 1955 and about 3.1 miles (5.0 km) long, connecting Nyack and Tarrytown. Today, it is crossed by the new Tappan Zee Bridge (officially the Governor Mario M. Cuomo Bridge), which opened in 2017 (north or westbound span) and 2018 (south or eastbound span) at about the same length as the old bridge. On September 14, 1609, the explorer Henry Hudson entered the Tappan Zee while sailing upstream from New York Harbor. At first, Hudson believed the widening of the river indicated that he had found the Northwest Passage. He proceeded upstream as far as present-day Troy before concluding that no such strait existed there. The Tappan Zee is mentioned several times in Washington Irving's famous short story, "The Legend of Sleepy Hollow." The tale is set in the vicinity of Tarrytown, in the area near Irving's own home at Sunnyside. In Frederik Pohl's 1977 Hugo award-winning novel Gateway, the main character Robinette Broadhead has "a summer apartment overlooking the Tappan Sea and The Palisades Dam." Pohl lived in the area while writing the book. Jazz pianist Bob James named one of the tracks from his 1977 album BJ4, in addition to his record label he founded, after the Tappan Zee.
