Less than 20 miles west of Portland, the city of Hillsboro is located in the Tualatin Valley of Washington County, Oregon, and is the fifth largest city in the state. Before becoming the city known as Hillsboro today, prior to the arrival of pioneer settlers, this area was a suitable region for many indigenous tribes commonly known as Tualatin Indians who settled here and traded their nomadic lives for fishing, hunting, foraging and developing agriculture. Some of the monuments still exist and pay tribute to the tribes who lived in this area in the past, and when you book an RV in Hillsboro, you may find some quaint rocks and boulders arranged in a very curious way, clearly indicating that a human hand arranged them! Also, a more recent homage to the Native American tribes is the Chief Kno-Tah wooden statue located in Shute Park, the oldest park in the city.
