House Bill 2119 passed through the Senate 46-3 Tuesday. It would designate Palouse Falls in southeastern Washington as the official state waterfall.
The measure passed through the House unanimously in February after the idea was suggested by elementary students in the nearby Washtucna School District.
Palouse Falls is located within Palouse Falls State Park about 69 miles northeast of Pasco. The falls drop about 200 feet from an upper to lower falls in a 377-foot canyon.
The falls and canyon were created by ice age floods from Lake Missoula that swept across eastern Washington 15,000 years ago, according to information from the Washington State Parks and Recreation Commission. The falls were eventually named Palouse Falls to commemorate the Palouse Native American culture.
