Goose Hollow is a neighborhood in southwest Portland, Oregon, United States. It acquired its distinctive name through early residents' practice of letting their geese run free in Tanner Creek Gulch and near the wooded ravine in the Tualatin Mountains known as the Tanner Creek Canyon. Tanner Creek Gulch was a 20-block-long, 50-foot-deep (15 m) gulch (or hollow) that started around SW 17th and Jefferson and carried the waters of Tanner Creek into Couch Lake (now the site of Old Town/Chinatown and the Pearl District). Over a century ago, Tanner Creek was buried 50 feet (15 m) underground (where it still drains the West Hills), and the Tanner Creek Gulch was infilled.
