Table Mountain (Skamania County, Washington)

Greenleaf Peak is a mountain in the Cascade Range in the U.S. state of Washington, located on the north side of the Columbia River near Table Mountain, in the Columbia River Gorge. The peak lies within the Columbia River Gorge National Scenic Area near Bonneville Dam. It is 3,424 feet (1,044 m) in elevation. Botanist David Douglas climbed to the summit in September 1825, making this the first recorded mountain ascent in what is now Washington state. Just south of the summit of Greenleaf Peak there is a dramatic escarpment called Red Bluffs, which connects Greenleaf Peak and Table Mountain. Approximately 1,300 feet (400 m) of the Eagle Creek formation are exposed at Red Bluffs. The Red Bluffs escarpment was created by the repeated collapse of Greenleaf Peak and Table Mountain. Massive landslides have fallen from the mountains, creating a 12-to-14-square-mile (31 to 36 km2) area of debris called the Cascade Landslide Complex. The largest and most studied landslide is known as the Bonneville Slide, which created the Bridge of the Gods and Cascade Rapids The topography of the landslide complex is uneven with roughly rolling hills and abrupt slopes. The whole area is inclined south toward and beyond the Columbia River. There may have been a cinder cone between Greenleaf Peak and Table Mountain which collapsed during the Bonneville Slide. The propensity of the area south of Greenleaf Peak and Table Mountain to collapse in landslides is due to the Eagle Creek formation. The rocks of the formation cover approximately 30 miles (48 km) of the Columbia River Gorge east of Cape Horn and consist of a mixture of past landslides, volcanic mud flows and ash falls. The formation is topped with basalt. Water can percolate through the basalt and saturate the Eagle Creek formation. In places where the formation is relatively close to the surface and inclined downslope, such as near Greenleaf Peak and Table Mountain, water saturation can cause the formation's material to slide away, carrying the overlying basalt with it.Between Greenleaf Peak and Table Mountain, and above the Red Bluffs, lies Greenleaf Basin. The basin averages 2,040 feet (620 m) in elevation and is covered with forested wetlands. Greenleaf Creek flows south through the basin before plunging as a waterfall over the Red Bluffs escarpment. In the winter of 2007-2008, there was a large landslide on the south slope of Greenleaf Peak, in the state-owned Table Mountain Natural Resources Conservation Area. Some 3 to 5 acres (12,000 to 20,000 m2) of a timbered rocky cliff slid, burying approximately 30 acres (120,000 m2) of forest under rubble. The slide was estimated to be about 750 feet (230 m) wide and 0.5 miles (0.80 km) long.

Beacon Rock State Park is a geologic preserve and public recreation area on Route 14 in the Columbia River Gorge National Scenic Area in Skamania County, Washington, United States. The park takes its name from Beacon Rock, an 848-foot (258 m) basalt volcanic plug on the north shore of the Columbia River 32 miles (51 km) east of Vancouver. On October 31, 1805, the Lewis and Clark Expedition arrived here and first measured tides on the river, indicating that they were nearing the ocean.

Cannabis Corner is the first city-owned cannabis shop with its first location at 420 Evergreen Drive, North Bonneville, Washington, USA. As of 2020, the main storefront is located in Stevenson, Washington.

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.

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.

Hamilton Creek is a tributary stream of the Columbia River in Skamania County, in the U.S. state of Washington.

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.

The Pierce National Wildlife Refuge is in southwest Washington within the Columbia River Gorge National Scenic Area. It encompasses wetlands and uplands along the north shore of the Columbia River west of the town of North Bonneville. Refuge habitats include wetlands, Columbia River riparian corridor blocks, transitional woodlands from willows to cottonwood/ash to white oak to Douglas fir, improved pastures with some native grasses, and numerous creeks, seeps, and springs.Hardy Creek, which bisects the refuge from east to west, supports one of the last remaining runs of chum salmon on the Columbia River. The creek also supports small remnant runs of coho salmon, steelhead, and Chinook salmon as well as a variety of native species of freshwater fish. The refuge headquarters also serves as the main office for Steigerwald Lake and Franz Lake National Wildlife Refuges. Visitor opportunities are limited to arranged group tours and viewing from the summit of Beacon Rock and the Hamilton Mountain Trail (both located in Beacon Rock State Park).

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.

Bonneville Lock and Dam consists of several run-of-the-river dam structures that together complete a span of the Columbia River between the U.S. states of Oregon and Washington at River Mile 146.1. The dam is located 40 miles (64 km) east of Portland, Oregon, in the Columbia River Gorge. The primary functions of Bonneville Lock and Dam are electrical power generation and river navigation. The dam was built and is managed by the United States Army Corps of Engineers. At the time of its construction in the 1930s it was the largest water impoundment project of its type in the nation, able to withstand flooding on an unprecedented scale. Electrical power generated at Bonneville is distributed by the Bonneville Power Administration. Bonneville Dam is named for Army Capt. Benjamin Bonneville, an early explorer credited with charting much of the Oregon Trail. The Bonneville Dam Historic District was designated a National Historic Landmark District in 1987.

John B. Yeon State Scenic Corridor is a state park in the U.S. state of Oregon, administered by the Oregon Parks and Recreation Department. It is located about 35 miles east of Portland in the Columbia Gorge. It is named in honor of John B. Yeon, one of the principal financiers of the Historic Columbia River Highway U.S. Route 30 which was constructed between 1913 and 1922. Located in the Columbia River Gorge National Scenic Area, the park features hiking trails that access some of the nearby waterfalls, including Elowah Falls.

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.
