Approximate location 4 miles north of Granada  

Sources identify Log Chain as a Pony Express relay station and a stop on the overland stage route.  Noble H. Rising, the stationkeeper, maintained a twenty four by forty foot log house and seventy foot barn.  Log Chain Station stood near Locknane Creek, also called Locklane and Muddy Creek on some maps. The origin of the name "Log Chain" is uncertain. Stories exist about pulling wagons across the creek's sandy bed with log chains, which may be one reason for its name. The station's name may also be a corruption of Locklane, the creek's name.

Over the years, Log Chain Station was altered to an unknown extent, perhaps with clapboard siding, but it still may stand on its original location. A marker of unknown nature has been placed above the front porch, indicating its connection with the Pony Express. 

It should be noted that some people have confused nearby Granada as a Pony Express station with the station at Log Chain.  Mattes and Henderson favor the station at Log Chain, four miles north of Granada, as the next stop. They believe that other authors' identification of the Granada station is "erroneous."  http://www.nps.gov/parkhistory/online_books/poex/hrs/hrs4b.htm
