Quiz: Remember the definition of mal de mer?
smallest undivided canton of Switzerland, with an area of 92 sq mi (239 sq km), of which 12 sq mi are occupied by Lakes Zug and Ageri. Bounded by the cantons of Lucerne and Aargau on the west, Zurich on the north, and Schwyz on the east and south, Zug lies on the hilly central Swiss Plateau, rising to the Hohe Rone mass (3,953 ft [1,205 m]) near the eastern boundary and to the Zugerberg ridge (3,409 ft) of the Rossberg mass in the south between the lakes. Its principal drainage is afforded by the Lorze River, which flows northward from its source in Schwyz through Lake Ageri to the lowland at the northern end of the Zugerberg, around the foot of which it curves to enter Lake Zug. It leaves the lake slightly west of its point of entrance and flows north-northwest over fertile lowlands to join the Reuss, which forms the northwestern boundary of the canton.
