Marker Name: From The Beginning Marker Type: City Marker Text: Riggins’ Geologic History, Flora and Fauna Before recorded history, the area we know as Riggins was on the west coast of the North American Continent. Thousands of miles to the west was the Pacific Plate, covered by ocean with only a few high points rising above the water. This plate was moving east at a rate of about six inches a year. About 100 million years ago, the Pacific Plate and the North American Continent collided in the area from Hells Canyon east to French Creek, about 20 miles up the Salmon River. The resulting heat and pressure changed the igneous stone in the impact zone from basalts and granites to metamorphic stone in which pockets of gold, silver, copper, and crystals were formed. This change is first visible in the greenstone outcrops and the large schist boulders with bands of quartz about five miles south of town and can be seen north to White Bird and east to French Creek along the Salmon RIver.
