The Antelope Island bar thus affords a tolerably complete record from 
1847 to 1865, but fails to give any later details. It happens, however, that 
the hiatus is filled at another locality. Stansbury Island is joined to the 
mainland by a similar bar, which was entirely above water at the time of 
Captain Stansbury’s survey, and so continued for many years. In 1866, 
the year following that in which the Antelope bar became unfordable, the 
water for the first time covered the Stansbury bar, and its subsequent 
advance and recession have so aftected the pursuits of the citizens of Grants- 
ville, who used the island for a winter herd ground, that it will not be 
difficult to obtain a full record by compiling their forced observations. 
Since undertaking the inquiry I have had no opportunity to visit that town, 
but the following facts have been elicited by correspondence. Since the 
first flooding of the bar the depth of water has never been less than 1 foot, 
and it has never been so great as to prevent fording in winter. But in the 
summers of 1872, 1873, and 1874, during the flood stage of the annual tide, 
there was no access except by boat, and in those years the lake level 
attained its greatest height. In the spring of 1869 the depth was 44 feet, 
and in the autumn of 1877, 24 feet. 
The last item shows that the Stansbury bar is 7 feet higher than the 
Antelope, and serves to connect the two series of observations. 
Further inquiries will probably render the record more complete and
