The range of the _Rocky or Chippewan Mountains_ divides the waters which flow east into the Missouri and Mississippi, from those which flow west into the Pacific Ocean, and are a continuation of the Cordilleras of Mexico. Their longitude is about one hundred and twelve west, and they terminate in about seventy north latitude. Along the coast of the Pacific is another range which seems to form a step to the Rocky Mountains. It extends from the Cape of California along the coast to Cook’s Inlet, generally rising to no great height in the southern portion. In the northern part, La Perouse states that it is ten thousand feet high, and at its northern extremity is Mount Elias, eighteen thousand feet high, and the loftiest peak of North America. The _White Mountains_ in New England, largely considered, are the principal ranges running north-east and south-west, projecting from the main ridge that forms the boundary of the United States, and separates the waters of the St. Lawrence from those that run south through the Northern States. The highest ridge is that called the White Mountain Ridge in New Hampshire, running from south to north, the loftiest summits of which are Monadnock, a hill of an abrupt and striking character, Sunapee, Kearsarge, Carr’s Mountain, and Moosehillock. Towards the north of the state, these eminences rise to a much higher elevation, and are known specifically by the name of the White Mountains. Illustration: White Mountains. Illustration: White Mountains. These are the loftiest mountains in the United States, east of the Mississippi. They lie between the Connecticut and Androscoggin rivers on the north-east and west, and the head-waters of the Merrimack on the south sixty or seventy miles from the coast; yet their white summits are visible from many miles at sea. They extend about twenty miles from south-west to north-east, and their base is eight or ten miles broad.
