Input: Question: Were the Creek and the Esopus both from the Hudson Valley? Passage:The creek, originally known as the "Esopus Kill", takes its name from the Esopus tribe of the Lenape, who were the Native American residents of the lower Esopus when the Dutch first explored and settled the Hudson Valley in the early 17th century. The creek's wide valley made it an ideal trading route for the Esopus and other Lenape who harvested the beaver pelts the European traders desired. Later, under the English, it became the beginning point for contentious land claims in the mountains. After independence, the Esopus corridor became the main route into the Catskills, first by road then later by the Ulster and Delaware Railroad, for forest-product industries like logging, tanning and charcoal-making. Those industries declined in the late 19th century, shortly before the creation of the Forest Preserve and the Catskill Park made the region more attractive for resorts and recreation, particularly trout fishing. The renewed Esopus also attracted the attention of fast-growing New York City, which was able to acquire land and build the reservoir and tunnel after overcoming local political opposition.
