Mohave County is located in the northwestern corner of the U.S. state of Arizona. As of 2007, its population was estimated to be 194,944, an increase of 39,912 people since the 2000 census count of 155,032. The county seat is Kingman. The largest city is Lake Havasu City.
Mohave County contains parts of Grand Canyon National Park and Lake Mead National Recreation Area and all of the Grand Canyon-Parashant National Monument. The Kaibab, Fort Mojave and Hualapai Indian Reservations also lie within the county.
Mohave County was the one of four original Arizona Counties created by the 1st Arizona Territorial Legislature. The county territory was originally defined as being west of latitude 113° 20' and north of the Bill Williams River. Pah-Ute County was created from it in 1865 and was merged back into Mohave County in 1871 when much of its territory was ceded to Nevada in 1866. The county's present boundaries were established in 1881.
According to the U.S. Census Bureau, the county has a total area of 13,470 square miles (34,886 km), of which, 13,312 square miles (34,477 km) of it is land and 158 square miles (409 km) of it (1.17%) is water. The county is the fifth largest U.S. county in area (excluding boroughs and census areas in Alaska), exceeded in size only by adjacent San Bernardino County, California (20,053 square miles), adjacent Coconino County (18,617 square miles), and the Nevada counties of Nye (18,147 square miles) and Elko (17,179 square miles).
The Colorado River forms most of the county's western boundary, and California, Nevada and Utah all border it. The river also runs east to west through Mohave County, dividing it between two of Arizona's geographic regions, the Arizona Strip in the north and the Mojave Desert in the south.

This county is created out of the northwestern part of the Territory,
and is surrounded on the west by the Colorado River. The remarks
heretofore made of the river valley in Yuma County will apply to this
county. The county lying east of the Colorado River is generally
rolling and hilly, covered with nutritious grasses and an abundance of
wood and timber. Stock thrives the year through without prepared food.
There is a free pasturage in this county alone, yet unoccupied, for
immense herds, and many valleys of excellent agricultural lands.
It has been known since the society of the Territory, that nearly all
the mountains in this county contained lodes of gold, silver, copper
and lead, and, in 1863, an attempt was made to developed and work some
of these lodes; some machinery was erected and considerable money
expended, but as has been the case in nearly all new mining counties,
hostility of Indians, extravagance, want of experience, etc., the
investments proved disastrous, and the mining interest has been
paralyzed, until within the past few months. Recently a few practical
miners undertook the task of giving new life to this abandoned and
almost forgotten field. Upon development, a number of lodes of gold and
silver have been found, rich and extensive. A population of about five
hundred miners has already accumulated in the Wallapai mining district.
Machinery is being erected, roads built, and mines developed with a
good prospect of excellent returns.
The inhabited places of the county are Mohave City, located on the
Colorado River; Hardyville, six miles above, and the Wallapai mining
district.
All merchandise are principally shipped up the Colorado River, and
landed either at Mohave or Hardyville, although wagon trains are
constantly running from Los Angeles with goods for this section and the
interior.
