They had all gathered at Celilo…gathered for the time of fishing and trading. The Warm Springs, Wascopum, Wasco, Tenino, Umatilla and Cayuse to the south, Yakama, Walla Walla, Palouse and Wanapum to the north, Nez Perce to the east. And more. Tribes from across the Northwest gathered each year for thousands of years at Celilo…where the salmon ran plenty and the water whorled down the gut.
