Bonneville Dam

Bonneville is an unincorporated community in Multnomah County, Oregon, United States, on Interstate 84 and the Columbia River. Bonneville is best known as the site of Bonneville Dam. North Bonneville, Washington is across the river. For decades before the dam was built, Bonneville was popular as a picnic spot for people living along the Columbia River between Portland and The Dalles, and the railroad company maintained an "eating house" for travelers there. Bonneville railroad station was named for explorer Benjamin Bonneville. The name "Bonneville" did not appear on maps until the late 1880s. Bonneville post office was established in 1900.

Tanner Creek is a creek located in the Columbia River Gorge in Multnomah County, Oregon, United States, that is a tributary of the Columbia River.

Fort Raines (spelled "Rains" on interpretive signs) was a United States Army blockhouse built in October 1855 to protect the portage road around the Cascades Rapids. It is located on the Washington side of the Columbia River, west of the Bridge of the Gods, at the "middle cascades." It was abandoned by 1857. The interpretive sign at the former site states that the post was "damp and lonely." Fort Raines was named for Brigadier General Gabriel J. Raines, who created anti-personnel mines for the Confederacy. Fort Raines had withstood the Cascades Massacre in 1856; but it was later destroyed in 1876. The only thing to remember Fort Raines was the Memorial Blockhouse that was erected near the original location in 1927. That too was destroyed and now there are only two informational signs near the site. Fort Raines was one of several of forts built to protect this portage road. Others included Fort Cascades, located near present-day North Bonneville, Washington, and Fort Lugenbeel.

Fort Cascades was a United States Army fort constructed in 1855 to protect the portage road around the final section of the Cascades Rapids, known as the "lower cascades." It was built on the Washington side of the Columbia River, between the present site of North Bonneville and the Bonneville Dam in Skamania County. It was burned in 1856, then rebuilt, but abandoned in 1861. A small community, Cascades, formed around the fort, but the largest flood of the Columbia River in recorded history passed over both the townsite and the fort site in 1894. Cascades served as the county seat of Skamania County prior to 1893, when the county records were moved to Stevenson, In 1867, decades before the disastrous floods, famed photographer Carleton Eugene Watkins arrived on the scene. Watkins took a commission from the Oregon Steam Ship Navigation Company to document areas of the Columbia River, with "Cascades" featuring prominently in his Pacific Coast stereoviews collection. Approximately 50 Watkins stereoscopic images of the Cascades area are known to exist, ranging from serials 1250-1302. Labeled "Upper Cascades," "Cascades" and "Lower Cascades," these photographs feature river view landscapes as well as images of the town and fort blockhouses. Aside from capturing scenery, Watkins documents saw mills, as well as train and riverboat traffic vital to the local economy at that time. A few of the images provide a glimpse of salmon fishing before the rapids were submerged by the construction of the Bonneville Dam. Although his negatives were destroyed in the great 1906 San Francisco earthquake, many of his printed images can be found in museums and private collections around the world.Fort Cascades is now on the National Register of Historic Places. There is a self-guided tour through what remains of the fort and the townsite. The trail the tour follows is approximately 1.5 miles (2.4 km) long. There is also a replica of a rock covered with petroglyphs that was originally located at the site but has since been moved to Stevenson. Fort Cascades is one of several forts built to protect the portage around the Cascade Rapids. Others are Fort Raines and Fort Lugenbeel.

North Bonneville is a city in the Columbia River Gorge National Scenic Area along the Columbia River in Skamania County, Washington, United States. The population was 593 at the 2000 census and 956 at the 2010 census.

Wahclella Falls is a waterfall along Tanner Creek, a tributary of the Columbia River, Multnomah County, Oregon, United States. It enters the river within the Columbia River Gorge.

The Bridge of the Gods was a natural dam created by the Bonneville Slide, a major landslide that dammed the Columbia River near present-day Cascade Locks, Oregon in the Pacific Northwest of the United States. The river eventually breached the bridge and washed much of it away, but the event is remembered in local legends of the Native Americans as the Bridge of the Gods. The Bridge of the Gods is also the name of a modern manmade bridge, across the Columbia River between Oregon and Washington.

The Oregon Portage Railroad was the first railroad in the U.S. state of Oregon. It was located on the south bank of the Cascades canal of the Columbia River.The railroad originally ran 4.5 miles (7.2 km) from Tanner Creek (near where Bonneville Dam was later built) to the Cascade Locks, which were under construction in the later years of the railroad's operation. It was later extended to a length of 15 miles (24 km).Although the Oregon Portage was the first railroad in Oregon, it was not the first along the Columbia River. Francis A. Chenoweth operated a rail line on the river's north bank in present-day Washington in 1851.

Sheridan State Scenic Corridor is a state park in the Columbia River Gorge, west of Cascade Locks, Oregon. The 11-acre (4.5 ha) property, containing an old-growth forest, is located on the south side of Interstate 84 at approximately milepoint 42.5, and was not accessible by motor vehicle since I-84 was built in 1960. However, with the opening of the Eagle Creek-Cascade Locks segment of the Historic Columbia River Highway State Trail in 1998, it has become easily accessible by foot or bicycle. The park is on a triangular lot, surrounded by I-84 and the Mount Hood National Forest. The park was acquired in 1923 from the Oregon-Washington Railroad and Navigation Company by the Parks Division of the State Highway Department, which named it for Philip H. Sheridan. It served as a wayside on US 30 - the Historic Columbia River Highway - until 1960, when the new I-84 freeway replaced the old road, cutting off access except through the national forest. As part of the restoration of the old highway, the Federal Highway Administration rebuilt the abandoned Eagle Creek-Cascade Locks for non-motorized traffic in the 1990s, to be managed by the State Parks and Recreation Department. An interpretive sign was installed at the site in 2007.Just to the east of the park, within the national forest the trail passes under I-84 in a 150-foot (50 m) long precast concrete rock-faced tunnel (45.6501°N 121.9107°W / 45.6501; -121.9107). The $500,000 structure was built as part of the restoration project, and was required to connect the park to another intact piece of road, located north of I-84 at the west Cascade Locks interchange.

Elowah Falls, also called McCord Creek Falls, is a 213-foot waterfall on the Columbia River Gorge, Multnomah County, Oregon, United States. Elowah Falls is one of several waterfalls along McCord Creek. The Creek and the waterfall are within the limits of the John B. Yeon State Scenic Corridor. The name of the waterfall carried the name of the creek that forms it: McCord Falls. In 1915 the Mazamas successfully had the falls renamed to Elowah. The meaning of the term is unknown.

Wahe Falls, also called Moffett Creek Falls, is an 80-foot waterfall on the Columbia River Gorge, Multnomah County, Oregon, United States. Wahe Falls is the last of several waterfalls along Moffett Creek. The mouth of the Creek is within the limits of the John B. Yeon State Scenic Corridor.

The Eagle Creek Fire was a destructive wildfire in the Columbia River Gorge, largely in the U.S. state of Oregon, with smaller spot-fires in Washington. The fire was started on September 2, 2017, by a 15-year-old boy igniting fireworks during a burn ban. The fire burned 50,000 acres, and burned for three months, before being declared completely contained. As late as May 29, 2018, it was still found smoldering in some areas.
