L.C. Bishop and Paul Henderson named and mapped Louis as a station between Troy and Kennekuk.  Lewin suggests that Lewis (also spelled Louis) was possibly the same as the Cold Spring Ranch Station. The Lewis Station and Cold Spring Station were located the same distance between Troy and Kennekuk. Lewin identifies the station as part of the Cold Spring Ranch near Syracuse.  However, one local history resource placed the station on North Independence Creek.  According to Raymond and Mary Settle, a mother and her four children lived at the relay station as cooks and stock tenders.  Several other sources give yet another location for this station. "Chain Pump" and "Valley Home/House" may be other names for the site as well.
