The people of the Umatilla, Walla Walla and Cayuse Tribes have lived in this area for thousands of years. They greeted the Lewis & Clark Expedition, traded with trappers, and helped emigrants along the Oregon Trail. Their spirit of hospitality continues as do their colorful pageantry and meaningful traditions. The Tribal people were an integral component to the very first Pendleton Round-Up and they continue to participate in the annual event with dancing and drumming competitions, and the nightly Happy Canyon Indian Pageant. The Tribes' influence and culture impacts the region year 'round and they welcome visitors to their home which now includes Wildhorse Resort & Casino, Tamastslikt Cultural Institute, a golf course, a business park and plans for more development, all infused with the same tradition passed down from generation to generation.
