Carson Sink/Sink of the Carson Station (N39 16 48.7 W118 47 40.6) 

In March of 1860, Bolivar Roberts, J.G. Kelly and others built this station. Today very little remains of this once busy station. 2 adobe walls of the corral are visible, but they are rapidly melting back into the alkali. In 1960, Walt Mulcahy found faint ruins of 4 – maybe live – buildings beside the corral. He said all of them faced north with 3 in a small flat just north of the dunes and 2 partially in the dunes.  http://www.expeditionutah.com/featured-trails/pony-express-trail/nevada-pony-express-stations/ 

CARSON SINK/SINK OF THE CARSON STATION 

Sources generally agree on the identity of this station, known as Carson Sink or Sink of the Carson.  Townley suggests the station, which had a good source of water nearby, began as a few brush shelters on George Chorpenning's mail route in 1859.  In March 1860, Bolivar Roberts, J. G. Kelly, and their crew built an adobe station and made other improvements there. When Richard Burton visited Carson Sink on October 17, 1860, he found a "frame house inside an adobe enclosure," inhabited by at least one grumpy, half-asleep station tender.  After the end of the Pony Express, the station functioned as a rest stop for travelers in the 1860s, and then as a hay ranch until its abandonment before the turn of the century.  Portions of the corral's adobe walls remain visible in 1979.51
