Hoyt Arboretum
Hoyt Arboretum is sited on steep slopes, straddling the SW Fairview Boulevard ridge above the Oregon Zoo and the Portland Japanese Garden. The elevation of the arboretum ranges from 650 feet to 900 feet, and there are several ravines within the arboretum. The hilly terrain of the arboretum was once in private hands. The United States government had granted land to American pioneers through the Donation Land Claim Act of 1850 for farming and logging, but the homesteads failed; by 1865, the land was owned by Multnomah County. In 1889, the area was ravaged by a forest fire, and part of the burned land was used to build the 160-acre (65-hectare) Multnomah County Poor Farm Hillside Farm west of Washington Park.
