John Le Conte, is given in
the _Overland Monthly_, being the result of some physical observations
made by the author at Lake Tahoe, in 1873. Lake Tahoe, also called Lake
Bigler, is situated at an altitude of 6,247 feet in the Sierra Nevada
Mountains, partly in California, partly in Nevada. The lake has a length
of 22 and a width of 12 miles. As regards its origin, the author regards
it as a "plication hollow," or a trough produced by the formation of two
mountain ridges, afterward modified by glacial agency. The depth of the
lake is remarkable; the observations taken at ten stations along the
length of the lake gave the following depths in feet: 900, 1,385, 1,495,
1,500, 1,506, 1,540, 1,504, 1,600, 1,640, 1645. This depth exceeds that
of the Swiss lakes proper--Lake Geneva, for example, has a maximum depth
of 1,096 feet--but is considerably less than that of Lakes Maggiore and
Como, on the Italian side of the Alps. A series of observations of the
temperature of the water were taken between the 11th and 18th of August.
