The Palouse Region

The rolling hills that characterise the Palouse are made of silt that has been shaped into dunes by the wind.

The Palouse is one of the world’s most productive farming regions, and America’s lentil producing capital.

The Grande Ronde Aquifer that lies under the Palouse contains enough water to fill Sydney Harbour 26 times.

Large-scale farming began in the Palouse in the 1880s, when white settlers first arrived in Washington.

The Grande Ronde Aquifer is the sole source of drinking water for 50,000 people in the Palouse Region.

The silt that makes up the Palouse Hills contains high levels of volcanic ash, deposited after eruptions from the nearby Cascade Mountains.
