Crapo Park (85 acres, 34 hectares) is a city park with arboretum and botanical garden, alongside the Mississippi River at Parkway Drive, Burlington, Iowa. Those who are not familiar with the park often mispronounce it as "crap-oh" Park, with the correct pronunciation being (/ˈkreɪpoʊ/ KRAY-poh) Park. It is reputed to be the site where the American flag was first raised on Iowa's soil, by Zebulon Pike in 1805.
The park includes an arboretum containing more than 200 varieties of trees and shrubs, as well as botanical gardens of annuals and perennials. As of 2003, the following park trees were on Iowa's statewide "Big Tree" list: Arizona cypress (Cupressus arizonica), black hickory (Carya glabra), pawpaw (Asimina triloba), and black walnut (Juglans nigra).(Wikipedia)
