Blazed Alder Creek is a tributary, about 4 miles (6 km) long, of the Bull Run River in the U.S. state of Oregon.[3] Part of the system that provides drinking water to the city of Portland, it flows generally north through a protected part of the Mount Hood National Forest in Clackamas and Multnomah counties. The creek is named after a 24-inch (61 cm) blazed (marked) alder tree that was used as a benchmark during early watershed surveys.[2]
