Peenpack, (Paan, Paen, Pien, Penn) is given, _traditionally,_ as the name of a "Small knoll or rise of ground, some fifty or sixty rods long, ten wide, and about twenty feet high above the level of" Neversink River, "on and around which the settlers of the Maghaghkamik Patent first located their cabins." It has been preserved for many generations as the name of what is known as the Peen-pach Valley, the long narrow flats on the Neversink. Apparently it is corrupt Dutch from _Paan-pacht,_ "Low, soft land," or leased land. The same name is met in _Paan-paach,_ Troy, N. Y., and in _Penpack,_ Somerset County, N. J. The places bearing it were primary Dutch settlements on low lands. (See Paanpaach.) Doubtfully a substitution for Algonquian from a root meaning, "To fall from a height" (Abn., _Paⁿna;_ Len. _Pange_), as in Abn. _Panaⁿk'i,_ "Fall of land," the downward slope of a mountain, suggested by the slope of the Shawongunk Mountain range, which here runs southwest to northeast and falls off on the west until it meets the narrow flats spoken of. The same feature is met at Troy.
Tehannek, traditionally the name of a small stream on the east side of the Peenpack Knoll, probably means "Cold stream," from _Ta_ or _Te,_ "cold," and _-hannek,_ "stream." It is a mountain brook.
Sokapach, traditionally the name of a spring in Deerpark, means, "A spring." It is an equivalent of _Sókapeék,_ "A spring or pool."
Neversink, the name quoted as that of the stream flowing to the Delaware at Carpenter's Point, is not a river name. It is a corruption of Lenape _Newás,_ "A promontory," and _-ink,_ locative, meaning "At the promontory." The particular promontory referred to seems to have been what is now known as Neversink Point, in Sullivan County, which rises 3,300 feet. The name is generic and is met in several places, notably in Neversink, N. J. (See Maghaghkameck.)
Seneyaughquan, given as the name of an Indian bridge which crossed the Neversink, may have its equivalent in "_Tayachquano,_ bridge--a dry passage over a stream." (Heckewelder.) The bridge was a log and the location said to have been above the junction of the stream with the Mamacottin.
Saukhekemeck, otherwise _Maghawam,_ so entered in the Schuyler Patent, 1697, apparently refer to one and the same place. The locative has not been ascertained. The patent covered lands now in New Jersey. The tract is described in the patent: "Situated upon a river called Mennissincks, before a certain island called Menagnock, which is adjacent to or near a tract of land called by the natives Maghaghkamek." (See Menagnock.)
