Tryon Creek
Tryon Creek is a 4.85-mile tributary of the Willamette River in the U.S. state of Oregon. The creek flows southeast from the Tualatin Mountains through the Multnomah Village neighborhood of Portland and the Tryon Creek State Natural Area. The bedrock under the watershed includes part of the last exotic terrane, a chain of seamounts acquired by the North American Plate as it moved west during the Eocene.
About Tryon Creek in brief
Tryon Creek is a 4. 85-mile tributary of the Willamette River in the U.S. state of Oregon. The creek flows southeast from the Tualatin Mountains through the Multnomah Village neighborhood of Portland and the Tryon Creek State Natural Area. The bedrock under the watershed includes part of the last exotic terrane, a chain of seamounts, acquired by the North American Plate as it moved west during the Eocene. Efforts to establish a large park in the watershed began in the 1950s and succeeded in 1975 when the state park was formally established. As of 2005, about 37 percent of the watershed was wooded and supported more than 60 species of birds as well as small mammals, amphibians, and fish. Two dormant volcanoes from the Boring Lava Field are in the tryon Creek watershed and are named for a mid-19th-century settler, Socrates Hotchkiss Tryon, Sr. The creek runs through forests of cedar and fir that were later logged by the Oregon Iron Company and others through the mid-20th century. The main stem runs through three closely spaced culverts with a combined length of 260 feet then flows on the surface before entering another culvert, 160 feet long under Southwest 30th Avenue at river mile 4. 56 or river kilometer 7. 34. It then flows out into the city of Lake Oswego and into the Portland and Clackamas County drainage basin of the Columbia River, where it is a tributaries of Falling Creek and Palatine Hill Creek.
It is named for the late-18th century settler Socrates HotChkiss tryon, Jr., who was a member of the Oregon Company of Iron and Steel, which was founded in the late 1800s and was responsible for the construction of the Iron Mountain Bridge and other structures in the area. It was named after a local resident, Socrates Tryon Sr., who died in the early 1900s and is buried in a shallow grave near the mouth of the creek. It flows through a series of rock pools and steps known as the Marshall Cascade from RM 3. 48 to RM 28. Arnold Creek, which is Tryon creek’s largestTributary, enters from the right 2. 68 miles from the mouth. Shortly thereafter, the creek passes under the Red Fox Bridge, which carries the Old Man Park Trail, which runs roughly 40 miles to the creek’s confluence with the river. Shortly after the confluence, the river flows out to the Nettle Creek Trail which runs about 0. 40 miles from the creek to the river’s mouth and then on to the South Creek Trail. In this stretch, the Middle Creek Trail parallels the stream along the right bank but crosses to the left bank at the bridge. At this point, the Fourth Avenue Trail runs parallel to the waterway along the leftbank. The waterway then flows to the Lewis and Clark Trail which merges with the creek along theleft bank.
