Back in 1989, Land Rover mounted an expedition to trek across the toughest lands the United States had to offer: the expansive Great Divide. The geological entity stretched from Colorado down to New Mexico and hosted numerous old mining towns established in the 1860s. Land Rover used the Great Divide Expedition to launch the then-new 1990 Range Rover. The SUVs used for the expedition were completely stock, save for more aggressive tires, bumper-mounted winches, and roof racks. Over 12 days the expedition moved south through the Great Divide while conquering unpaved or non-road surfaces during more than 75 percent of the distance.
