LA CROSSE COUNTY HISTORICAL SKETCHES

of these expeditions that he gathered the following data on the vicinity
of La Crosse.
Nicollet, I. (Joseph) N. Report Intended To Illustrate a Map of the Hydro-
    graphical Basin of the Upper Mississippi. Washington. 1841.
    P. 122. "Mouth of the Prairie de la Crosse river:
             3 miles north from the mouth of the Hokah (Root) River.
             2,004 miles from the mouth of the Mississippi.
             North latitude, 43 degrees, 49 minutes.
             Longitude, 91 degrees, 14 minutes west.
     "Black River (Sappah), old mouth:
             683 feet altitude above the Gulf of Mexico.
             31 [an error; 10 mi.] miles from the mouth of the La
                  Crosse River.
             2,035 miles from the mouth of the Mississippi.
             North latitude, 43 degrees, 57 minutes, 14 seconds.
     "Dividing ridge between LaCrosse and Black Rivers:
             6 miles east of the Mississippi and 1,103 feet altitude
                  above the Gulf."
     No exact date is given for these observations, but it is probable
that they were taken between 1836 and 1839, since Nicollet made sim-
ilar observations, he says, between St. Louis and St. Peter's during those
years.

of La Crosse were examined and found to contain no mention of the
place.
