This site was presumably located one and one-half miles northeast of Lowell in Kearney County and for a time served as a relay station for the Pony Express. 

Even though Bishop and Henderson list Kearney Station separately from Hook Station,  a number of authors use a variety of names to describe the same station including Hook's, Hook's Station, Hook's Ranch, Kearney Station, Dogtown, Valley City, Valley Station, Junction City, Hinshaw's Ranch, and Omaha Junction.  Whichever name is associated with this station, M. H. Hook managed the station operations at the site. This station was the last one under the jurisdiction of St. Joseph-Fort Kearney Division Superintendent E. A. Lewis.
