The impact of these floods covers 16,000 square miles thousands (41,440 km2) in the Pacific Northwest. This large area iniclude parts of Montana, Idaho, Washington and Oregon. Today the efforts of many public and private groups support better understanding and appriciation for the unique Ice Age Floods features.
